CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202111335122.2, filed on November 11, 2021, and Chinese Patent Application No. 202221824546.5, filed on July 15, 2022, the contents of each of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure generally relates to information prompting, and more particularly, relates to systems and methods for prompting abnormal conditions of medical systems.

BACKGROUND

A medical system always includes a high technology content and a complex structure. Therefore, when the medical system includes an abnormal condition, a user cannot solve the abnormal condition. At this point, the user needs to contact a service engineer responsible for the medical system. However, since the service engineer needs to maintain a large area of medical systems, the service engineer is often not on site where the abnormal condition of the medical system occurs. In addition, different abnormal conditions of the medical system may require the service engineer to carry different repair equipment. Therefore, if the service engineer can obtain abnormal information of the medical system in advance, the service engineer can rush to the scene with the corresponding repair equipment. Alternatively, the service engineer can remotely control or instruct the user to solve the abnormal condition.

Therefore, it is desirable to provide systems and methods for prompting the abnormal condition of the medical system, which can efficiently and accurately provide prompt information for prompting the abnormal information of the medical system.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant disclosure. However, it should be apparent to those skilled in the art that the present disclosure may be practiced without such details. In other instances, well-known methods, procedures, systems, components, and/or circuitry have been described at a relatively high level, without detail, in order to avoid unnecessarily obscuring aspects of the present disclosure. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the present disclosure is not limited to the embodiments shown, but to be accorded the widest scope consistent with the claims.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a, ” “an, ” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprise, ” “comprises, ” and/or “comprising, ” “include, ” “includes, ” and/or “including, ” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be understood that when a unit, engine, module, or block is referred to as being “on, ” “connected to, ” or “coupled to, ” another unit, engine, module, or block, it may be directly on, connected or coupled to, or communicate with the other unit, engine, module, or block, or an intervening unit, engine, module, or block may be present, unless the context clearly indicates otherwise. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

These and other features, and characteristics of the present disclosure, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, may become more apparent upon consideration of the following description with reference to the accompanying drawings, all of which form a part of this disclosure. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended to limit the scope of the present disclosure. It is understood that the drawings are not to scale.

An aspect of the present disclosure relates to systems and methods for prompting. The method may include determining, based on operational data of a medical system, abnormal information of the medical system. Further, the method may include generating prompt information for prompting the abnormal information of the medical system. The prompt information may include image data encoding at least one of the abnormal information or system information of the medical system. By encoding the abnormal information in the image data, enough information may be provided to the target user to determine the abnormal condition of the medical system when the target user does not arrive on site. In addition, the prompt information may be generated through an encoding manner, which can reduce a possibility that the prompt information is lost during the transmission, thereby improving the accuracy of the prompt information during the transmission.

Another aspect of the present disclosure relates to a rod source phantom irrigation system. The rod source phantom irrigation system may include a source liquid production module, a conveying module, a rod source module, and a control module. The rod source phantom may be automatically generated without a manual operation (e.g., a manual injection of the radioactive source and/or the solvent, a manual mixture, etc. ) , which can avoid a contact of a user with the radioactive source, thereby reducing the irradiation of the radioactive source to the user, reducing the damage to the user, and improve the safety during the rod source irrigation. In addition, by automatically generating the rod source phantom, the rod source phantom irrigation system may improve the efficiency of the generation of the rod source phantom.

Still another aspect of the present disclosure, the systems and methods for prompting may be applied to the rod source phantom irrigation system. Therefore, when the rod source phantom irrigation system includes an abnormal condition, the prompt information may be generated and/or transmitted automatically, which needs no contact between the user and the rod source phantom irrigation system, thereby reducing the irradiation of the radioactive source to the user and the damage to the user.

The control module may be in communication with the source liquid production module and the conveying module, respectively. In some embodiments, the control module may be configured to control the source liquid production module to generate the mixed solution and the conveying module to transmit the mixed solution. More descriptions regarding the rod source phantom irrigation system may be found elsewhere in the present disclosure (e.g., FIGs. 2-11 and the descriptions thereof) .

The network 120 may include any suitable network that can facilitate the exchange of information and/or data for the prompting system 100. In some embodiments, one or more components (e.g., the medical system 110, the terminal 130, the processing device 140, the storage device 150, etc. ) of the prompting system 100 may communicate information and/or data with one or more other components of the prompting system 100 via the network 120.

FIG. 2 is a schematic diagram illustrating an exemplary rod source phantom irrigation system 200 according to some embodiments of the present disclosure.

PET-CT device is a scanning device configured to obtain an organ function and/or a metabolism condition of a subject, which can be widely used in fields, e.g., detection and/or diagnosis of a tumor, a brain, a heart, etc. In order to ensure scanning accuracy and detection efficiency of the PET-CT device, the PET-CT device needs to be performed a quality detection. During the quality detection, a rod source phantom including a radioactive source is caused to rotate uniformly around an axis of the PET-CT device to uniformly irradiate detection units of the PET-CT device.

Conventionally, the rod source phantom may be prepared manually. For example, a user injects a radioactive source (e.g., a fluorodeoxyglucose (FDG) source) and a solvent into a rod source phantom according to a proportion between the radioactive source and the solvent, and shakes the rod source phantom to uniformly mix the radioactive source and the solvent. However, during the preparation of the rod source phantom, the user may be continuously irradiated by the radioactive source, which can damage the user. Therefore, the rod source phantom irrigation system 200 may be provided to automatically prepare the rod source phantom.

As shown in FIG. 2, the rod source phantom irrigation system 200 may include a source liquid production module 210, a conveying module 220, a rod source module 230, and a control module 240. The rod source module 230 may include a rod source phantom 232. The source liquid production module 210 may be connected to the conveying module 220. The conveying module 220 may be connected to the rod source phantom 232 in the rod source module 230. The control module 240 may be in communication with the source liquid production module 210 and the conveying module 220, respectively.

The source liquid production module 210 may be configured to generate, based on a first instruction sent by the control module 240, a mixed solution by mixing an injected radioactive source and a solvent with a preset ratio. The conveying module 220 may be configured to transmit, based on a second instruction sent by the control module 240, the mixed solution from the source liquid production module 210 to the rod source phantom 232 in the rod source module 230. The control module 240 may be configured to control the source liquid production module 210 to generate the mixed solution and the conveying module 220 to transmit the mixed solution.

In some embodiments, the radioactive source and the solvent may be injected into the source liquid production module 210 manually. For example, the user may extract the radioactive source and the solvent with the preset ratio, and inject the radioactive source and the solvent into the source liquid production module 210. In some embodiments, the radioactive source and the solvent may be injected into the source liquid production module 210 automatically. For example, the source liquid production module 210 may be connected to a first container storing the radioactive source and a second container storing the solvent, respectively. The radioactive source and the solvent with the preset ratio may be automatically flowed into the source liquid production module 210. Alternatively, a first amount of the radioactive source may be automatically output by controlling the first container, and a second amount of the solvent may be automatically output by controlling the second container, thereby injecting the radioactive source and the solvent with the preset ratio into the source liquid production module 210.

In some embodiments, the rod source phantom irrigation system 200 may further include a source irrigation module (not shown) . The source irrigation module may be configured to inject the radioactive source and the solvent with the preset ratio into the source liquid production module 210. For example, after the source irrigation module receives an irrigation instruction sent by the control module 240, the source irrigation module may automatically inject the radioactive source and the solvent with the preset ratio to the rod source phantom 232 in the source liquid production module 210.

In some embodiments, after the radioactive source and the solvent with the preset ratio are injected into the source liquid production module 210, the source liquid production module 210 may be configured to uniformly mix the radioactive source and the solvent. In some embodiments, in response to a trigger operation of the user, the control module 240 may send the first instruction to the liquid production module 210 for mixing the radioactive source and the solvent. Alternatively, in response to determining that the radioactive source and the solvent with the preset ratio are injected into the source liquid production module 210, the control module 240 may send the first instruction to the liquid production module 210 for mixing the radioactive source and the solvent.

Merely by way of example, in response to determining that the radioactive source and the solvent with the preset ratio are injected into the source liquid production module 210, the source liquid production module 210 may send an instruction that the radioactive source and the solvent have been injected, so as to cause the control module 240 to output the first instruction. Alternatively, the control module 240 may be connected to the first container storing the radioactive source and the second container storing the solvent, respectively. The control module 240 may receive an instruction that the radioactive source has been injected into the source liquid production module 210 from the first container, and receive an instruction that the solvent has been injected into the source liquid production module 210 from the second container. Accordingly, the control module 240 may send the first instruction to the source liquid production module 210. In some embodiments, the control module 240 may be further connected to a detection component. After the detection component determines that the radioactive source and the solvent have been injected, the detection component may send an instruction that the radioactive source and the solvent have been injected, so as to cause the control module 240 to output the first instruction. It should be noted that a manner that the control module 240 determines whether the radioactive source and the solvent with the preset ratio have been injected into the source liquid production module 210 is not limited herein. In addition, a manner that the control module 240 outputs the first instruction may not be limited herein.

In some embodiments, after the source liquid production module 210 receives the first instruction sent by the control module 240, the source liquid production module 210 may generate, based on the first instruction, the mixed solution by mixing the injected radioactive source and the solvent with the preset ratio. In some embodiments, the source liquid production module 210 may mix the injected radioactive source and the solvent through a mixture manner, e.g., rapid rotation, rapid movement, rapid stirring, or the like, or any combination thereof. In some embodiments, the solvent may include water, ethanol, or the like, or any combination thereof. For example, the solvent may be determined based on actual requirements (e.g., a type of the mixed solution) .

In some embodiments, the first instruction may further include a mixture time. For example, the source liquid production module 210 may mix the injected radioactive source and the solvent from a start time to an end time, and a time period between the start time and the end time may be the mixture time. In some embodiments, after the control module 240 sends the first instruction to the source liquid production module 210, the control module 240 may send a mixture stopping instruction to the source liquid production module 210 until the mixture time arrives. The source liquid production module 210 may receive the mixture stopping instruction, and stop the mixing of the radioactive source and the solvent. In some embodiments, a mixture operation of the source liquid production module 210 may be an operation with an operation time. For example, the source liquid production module 210 may stop the mixing of the radioactive source and the solvent after the mixture operation with the operation time is performed. In some embodiments, the time period of the mixture time may be determined based on a system default setting or set manually by the user. For example, the time period of the mixture time may be a default time period. As another example, the time period of the mixture time may be determined based on a total volume of the mixed solution. As still another example, the time period of the mixture time may be set based on an input of the user. For instance, the user may manually adjust the time period of the mixture time. In some embodiments, the user may stop the mixing. For example, the user may trigger a stop button to stop the mixing. Accordingly, after the control module 240 determines that the stop button is triggered by the user, the control module 240 may send the mixture stopping instruction to the source liquid production module 210, so as to cause the source liquid production module 210 to stop the mixing of the radioactive source and the solvent.

In some embodiments, after the source liquid production module 210 generates the mixed solution by mixing the radioactive source and the solvent, the source liquid production module 210 may send a mixing completion instruction to the control module 240. The control module 240 may determine, based on the mixing completion instruction, that the mixed solution has been generated. And then, the control module 240 may send the second instruction to the conveying module 220. After the conveying module 220 receives the second instruction, the conveying module 220 may transmit the mixed solution from the source liquid production module 210 to the rod source phantom 232 in the rod source module 230.

In some embodiments, the source liquid production module 210 may be connected to the conveying module 220. A connection between the source liquid production module 210 and the conveying module 220 may be disposed with a conveying switch. Alternatively, the conveying switch may be disposed on the conveying module 220. It should be noted that, a position and/or a type of the conveying switch may not be limited herein, as long as the conveying switch can be used to control the flow of the mixed solution. In some embodiments, the source liquid production module 210 may be connected to the conveying module 220 in any manner, which is not limited herein. For example, the conveying module 220 may be connected to the source liquid production module 210 through a bottom portion of the source liquid production module 210. As another example, the conveying module 220 may be connected to the source liquid production module 210 by extending from a top portion of the source liquid production module 210 to the inside of the source liquid production module 210. As still another example, the conveying module 220 may be connected to the source liquid production module 210 through another portion of the source liquid production module 210.

The rod source phantom irrigation system 300 may be an embodiment of the rod source phantom irrigation system 200 described in FIG. 2. As shown in FIG. 3, a conveying module 320 may be connected to a source liquid production module 310 through a bottom portion of the source liquid production module 310. A conveying switch 322 may be disposed on the conveying module 320. When the conveying module 320 receives a second instruction sent by a control module (e.g., the control module 240) , the conveying module 320 may be caused to open the conveying switch 322, so as to automatically transmit a mixed solution from the source liquid production module 310 to a rod source phantom 332 in a rod source module (e.g., the rod source module 230) .

As another example, referring to FIG. 4, FIG. 4 is a schematic diagram illustrating an exemplary rod source phantom irrigation system 400 according to some embodiments of the present disclosure. The rod source phantom irrigation system 400 may be an embodiment of the rod source phantom irrigation system 400 described in FIG. 4. As shown in FIG. 4, a conveying module 420 may be connected to a source liquid production module 410 by extending from a top portion of the source liquid production module 410 to the inside or a bottom portion of the source liquid production module 410. A conveying switch 422 may be disposed on the conveying module 420. When the conveying module 420 receives a second instruction sent by a control module (e.g., the control module 240) , the conveying module 420 may be caused to open the conveying switch 422, so as to transmit, through a pumping manner, the mixed solution from the source liquid production module 410 to a rod source phantom 432 in a rod source module (e.g., the rod source module 230) .

It should be noted that, the descriptions of the connection between the conveying module and the source liquid production component are merely provided for illustration, and not intended to limit the scope of the present disclosure. For example, the connection between the conveying module and the source liquid production component may include no conveying switch. For instance, when the conveying module is connected to the source liquid production component by extending from the top portion of the source liquid production component to the inside or the bottom portion of the source liquid production component, and the conveying module receives the second instruction sent by the control module, the conveying module may transmit, through the pumping manner, the mixed solution from the source liquid production module to the rod source phantom in the rod source module.

In some embodiments, the rod source module 230 may include a rod source phantom fixing unit 234 (e.g., a groove structure as shown in FIG. 5) . The rod source phantom fixing unit 234 may be configured to fix the rod source phantom 232. In some embodiments, the rod source phantom fixing unit 234 may include a slot, a groove, a clamp, etc. The slot may be a slot with a fixed size or a slot with a variable size. When the slot is a slot with a fixed size, the rod source module 230 may include one or more slots with fixed sizes for fixing rod source phantoms 232 with different sizes. The displacement of the groove may be similar to the displacement of the slot, which is not repeated herein. The clamp may be a clamp with a variable size for fixing rod source phantoms 232 with different sizes. It should be noted that, a shape of the rod source phantom fixing unit 234 of the rod source phantom 232 is not limited in the present disclosure.

Merely by way of example, referring to FIG. 5, FIG. 5 is a schematic diagram illustrating exemplary structures of rod source phantom fixing units according to some embodiments of the present disclosure. A count of rod source phantom fixing units 234 may be multiple. For example, as shown in FIG. 5, a rod source phantom irrigation system may include three rod source phantom fixing units 234. Each of the three rod source phantom fixing units 234 may include a fixing base with a groove 236. The groove 236 may be used for fixing the rod source phantom 232. A size of each groove may be different from sizes of other grooves. The grooves with different sizes may be used to fix rod source phantoms 232 with different sizes. In some embodiments, a size of each fixing base may be the same as sizes of other fixing bases. When rod source phantoms 232 with different sizes are irrigated, each of the rod source phantoms 232 may be matched with a rod source phantom fixing unit 234 based on the size of the rod source phantom 232 and the size of the rod source phantom fixing unit 234. For example, when a size of a rod source phantom 232 is the same as or similar to a size of a rod source phantom fixing unit 234, the rod source phantom 232 may be determined to match with the rod source phantom fixing unit 234. After the rod source phantom 232 is fixed by the rod source phantom fixing unit 234, the rod source phantom fixing unit 234 may be fixed on a fixing position of the rod source module 230. A size of the fixing position may be matched with the size of the fixing base. For example, the size of the fixing position may be the same as or similar to the size of the fixing base.

Therefore, the user (e.g., an operator) may fix the rod source phantoms 232 with different types and/or different sizes on the fixing position of the rod source module 230. For example, an end of the conveying module 220 may be connected to the rod source phantom 232 manually. Therefore, the conveying module 220 may transmit, under a control of the control module 240, the mixed solution from the source liquid production module 210 to the rod source phantom 232 in the rod source module 230. In some embodiments, the conveying module 220 may be connected to the rod source phantom 232 automatically. For example, the conveying module 220 may be automatically connected to the rod source phantom 232 under a control of the control module 240, and automatically disconnected to the rod source phantom 232 after the conveying module 220 transmits the mixed solution from the source liquid production module 210 to the rod source phantom 232 in the rod source module 230.

In some embodiments, the rod source module 230 may further include a pressure sensor (not shown) . The pressure sensor may be in communication with the control module. In some embodiments, the pressure sensor may be configured to detect a pressure on the rod source phantom fixing unit 234 and transmit the detected pressure to the control module 240. After the control module 240 receives the detected pressure, the control module 240 may determine, based on the detected pressure, a type of the rod source phantom 232. For example, different rod source phantoms may correspond to different pressures, and the control module 240 may determine the type of the rod source phantom 232 based on the detected pressure. In some embodiments, the control module 240 may further determine, based on the type of the rod source phantom, at least one operational parameter of the rod source phantom irrigation system 200. Exemplary operational parameters may include a first operational parameter of a cover opening module, a second operational parameter of a liquid level detection module, a third operational parameter (e.g., the mixture manner, the mixture time, etc. ) of the source liquid production module 210, or the like, or any combination thereof.

In some embodiments, after the rod source phantom 232 is fixed on the rod source module 230, the rod source phantom irrigation system 200 may be initiated to cause the control module 240 of the rod source phantom irrigation system 200 to operate. In some embodiments, the rod source phantom irrigation system 200 may be disposed with an initiation button. After the control module 240 determines that the initiation button is triggered, the control module 240 may start to operate. In some embodiments, the rod source phantom irrigation system 200 may include a display component (e.g., a user interaction module 1070 as shown in FIG. 10) . The display component may include an initiation key. After the control module 240 determines that the initiation key is triggered, the control module 240 may start to operate. In some embodiments, the rod source phantom irrigation system 200 may further include a communication component. The control module 240 may receive an instruction (e.g., the first instruction, the second instruction, etc. ) sent by an external component through the communication component. That is, the control module 240 may be remotely controlled through the external component. When the control module 240 receives an initiation instruction sent by the external component, the control module 240 may start to operate. It should be noted that, the initiation manner of the control module 240 is not limited in the present disclosure.

In some embodiments, the rod source phantom irrigation system 200 may include an output module. The output module may be configured to output, under the control of the control module 240, a completion instruction after the rod source phantom is irrigated. The output module may include a buzzer, a speaker, a voice broadcast component, an indicator light, or the like, or any combination thereof.

In some embodiments, the source phantom irrigation system 200 may include a detection module. The detection module may be configured to detect each component of the rod source phantom irrigation system 200. For example, after a detection instruction is received, the detection module may obtain a current value of the at least one operational parameter of the rod source phantom irrigation system 200 by detecting each component of the rod source phantom irrigation system 200, and then abnormal information of the rod source phantom irrigation system 200 may be determined.

According to some embodiments of the present disclosure, the rod source phantom irrigation system 200 may generate the mixed solution by automatically mixing the radioactive source and the solvent, and obtain the rod source phantom including uniform radioactive substances by automatically irrigating the mixed solution into the rod source phantom. Further, the rod source phantom may be used for quality detection of a PET-CT device. The rod source phantom may be automatically generated without a manual operation (e.g., a manual injection of the radioactive source and/or the solvent, a manual mixture, etc. ) , which can avoid a contact of the user with the radioactive source, thereby reducing the irradiation of the radioactive source to the user, reducing the damage to the user, and improve the safety during the rod source irrigation. In addition, by automatically generating the rod source phantom, the rod source phantom irrigation system 200 may improve the efficiency of the generation of the rod source phantom.

It should be noted that the rod source phantom irrigation systems are provided for illustration purposes, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure.

FIG. 6 is a schematic diagram illustrating an exemplary rod source phantom irrigation system 600 according to some embodiments of the present disclosure. The rod source phantom irrigation system 600 may be an embodiment of the rod source phantom irrigation system 200 described in FIG. 2.

The control module 640 may be in communication with the stirring unit 614 and the conveying control unit 624, respectively.

The stirring unit 614 may be configured to receive a first instruction sent by the control module 640, and generate, based on the first instruction, a mixed solution by mixing a radioactive source and a solvent with a preset ratio that are injected into the liquid container 612. The conveying module 620 may be configured to receive a second instruction sent by the control module 640 after the mixed solution is generated, and transmit, based on the second instruction, the mixed solution from the liquid container 612 to the rod source phantom 632 in the rod source module 630.

In some embodiments, the liquid container 612 may be a closed container, an opened container, or a semi-closed container that can be opened or closed. In some embodiments, a shape of the liquid container 612 may include a spherical container, a cylindrical container, a conical flask, or the like, or any combination thereof. It should be noted that a structure, a shape, a size, a material, etc., of the liquid container 612 are not limited.

In some embodiments, the stirring unit 614 disposed in the liquid container 612 may include a rotatable stirring rod. The stirring rod may be controlled to rotate to obtain the mixed solution. In some embodiments, a structure of the stirring rod may include a straight structure, a screw structure, a jagged structure, or the like, or any combination thereof. It should be noted that a structure, a material, a length, etc., of the stirring rod are not limited.

In some embodiments, the stirring unit 614 may include a mixer. The mixer may include one or more blades. For example, the mixer may be disposed in the liquid container 612 through a connecting rod. As another example, the mixer may be disposed on a bottom portion of the liquid container 612 through a connecting member. The mixed solution may be obtained by controlling a rapid rotation of the mixer. It should be noted that a structure, a shape, a shape, a material, a fixing position, a fixing manner, etc., of the mixer are not limited.

In some embodiments, after the radioactive source and the solvent with the preset ratio are injected into the liquid container 612, the control module 640 may send the first instruction to the stirring unit 614. After the first instruction is received, the stirring unit 614 may start to operate, so as to generate the mixed solution by mixing the radioactive source and the solvent with the preset ratio that are injected into the liquid container 612. In some embodiments, the stirring unit 614 may receive an instruction for stopping stirring sent by the control module 640, and stop the mixing of the radioactive source and the solvent based on the instruction for stopping stirring.

Merely by way of example, referring to FIG. 7, FIG. 7 is a schematic diagram illustrating an exemplary source liquid production module 700 according to some embodiments of the present disclosure. The source liquid production module 700 may be an embodiment of the source liquid production module 610 described in FIG. 6. As shown in FIG. 7, the source liquid production module 700 may include a liquid container 710 and a stirring unit 720. The stirring unit 720 may include a first driving unit 722 and a stirring rod 724. The first driving unit 722 may be configured to receive a first instruction, and control the stirring rod 724 to rotate based on the first instruction.

As another example, referring to FIG. 8, FIG. 8 is a schematic diagram illustrating an exemplary source liquid production module 800 according to some embodiments of the present disclosure. The source liquid production module 800 may be an embodiment of the source liquid production module 610 described in FIG. 6. As shown in FIG. 8, the source liquid production module 800 may include a liquid container 810 and a stirring unit 820. The stirring unit 820 may include a second driving unit 822, a connecting member 824, and one or more stirring blades 826. The one or more stirring blades 826 may be disposed on an end of the connecting member 824 near a bottom portion of the liquid container 810. The second driving unit 822 may be configured to receive a first instruction, and control the one or more stirring blades 826 to rotate based on the first instruction. In some embodiments, the one or more stirring blades 826 may be fixedly connected to the connecting member 824. When the one or more stirring blades 826 rotate, the one or more stirring blades 826 may rotate together with the connecting member 824. In some embodiments, the one or more stirring blades 826 may be movably connected to the connecting member 824. When the one or more stirring blades 826 rotate, the connecting member 824 may not rotate together with the one or more stirring blades 826. In some embodiments, the connecting member 824 may include a connecting rod, a connecting tube, or the like, or any combination thereof. In some embodiments, the second driving unit 822 may be disposed at one end of the connecting member 824 away from the bottom portion of the liquid container 810. The second driving unit 822 may drive the one or more stirring blades 826 to rotate by controlling a rotation of the connecting member 824. Alternatively, the second driving unit 822 may directly control the one or more stirring blades 826 to rotate.

In some embodiments, the first end of the conveying pipe 622 may be fixedly connected with the liquid container 612. For example, the first end of the conveying pipe 622 may be fixedly connected with the bottom portion of the liquid container 612. As another example, the first end of the conveying pipe 622 may extend from the top portion of the liquid container 612 to the bottom portion of the liquid container 612. As still another example, the first end of the conveying pipe 622 may be fixedly connected with a side portion of the liquid container 612.

In some embodiments, a flow of the mixed solution may be controlled through the conveying control unit 624. For example, when the mixed solution needs to be transmitted to the rod source phantom 632 in the rod source module 630, the conveying pipe 622 may be opened through the conveying control unit 624. As another example, when no mixed solution needs to be transmitted to the rod source phantom 632, the conveying pipe 622 may be closed through the conveying control unit 624.

In some embodiments, the second end of the conveying pipe 622 may be movably connected with the rod source phantom 632. For example, when the rod source phantom 632 needs to be irrigated (i.e., the conveying control unit 624 receives the second instruction sent by the control module 640) , the conveying control unit 624 may control the second end of the conveying pipe 622 to extend into the inside of the rod source phantom 632 and be connected with the rod source phantom 632. After the source phantom 1032 has be irrigated, the conveying control unit 624 may control the second end of the conveying pipe 622 to move from the inside of the rod source phantom 632 to a position outside the rod source phantom 632. In some embodiments, a portion of the conveying pipe 622 near the second end of the conveying pipe 622 may be a retractable conduit. Alternatively, the portion of the conveying pipe 622 near the second end of the conveying pipe 622 may be connected with other portions of the conveying pipe 622 through a movable connecting member. The movable connecting member may control the portion of the conveying pipe 622 near the second end of the conveying pipe 622 to move up and down and/or move left and right.

According to some embodiments of the present disclosure, the rod source phantom irrigation system 600 may be provided for automatically generating the mixed solution and irrigating the rod source phantom, which can improve the realizability and the efficiency of the generation of the rod source phantom.

FIG. 9 is a schematic diagram illustrating an exemplary rod source phantom irrigation system 900 according to some embodiments of the present disclosure. The rod source phantom irrigation system 900 may be an embodiment of the rod source phantom irrigation system 200 described in FIG. 2.

As shown in FIG. 9, the rod source phantom irrigation system 900 may include a source liquid production module 910, a conveying module 920, a rod source module 930, a control module 940, a cover opening module 950, and a liquid level detection module 960.

The source liquid production module 910 may include a liquid container 912 and a stirring unit 914. The stirring unit 914 may be disposed in the liquid container 912. The conveying module 920 may include a conveying pipe 922 and a conveying control unit 924. The rod source module 930 may include a rod source phantom 932. The cover opening module 950 may be in communication with the control module 940. The liquid level detection module 960 may be in communication with the control module 940.

The cover opening module 950 may be configured to receive a third instruction sent by the control module 940 before the conveying module 920 transmits a mixed solution, and open a cover of the rod source phantom 932 based on the third instruction. In some embodiments, the cover opening module 950 may be configured to receive a fourth instruction sent by the control module 940 after the mixed solution has been transmitted, and close the cover of the rod source phantom 932 based on the fourth instruction.

In some embodiments, when the cover opening module 950 receives the third instruction sent by the control module 940, the cover opening module 950 may be moved to a position corresponding to the cover of the rod source phantom 932, and control to open the cover of the rod source phantom 932. After the cover of the rod source phantom 932 is opened, the cover opening module 950 may be moved to another position until the cover opening module 950 receives an instruction (e.g., the fourth instruction) . When the cover opening module 950 receives the fourth instruction, the cover opening module 950 may be moved to the position corresponding to the cover of the rod source phantom 932, and close the cover of the rod source phantom 932 based on the fourth instruction. It should be noted that an opening and/or closing manner that the cover opening module 950 opens and/or closes the cover of the rod source phantom 932 may be associated with a cover structure of the cover. That is, different cover structures may correspond to different manners. In some embodiments, the manner that the cover opening module 950 opens and/or closes the cover of the rod source phantom 932 may be matched with the cover structure of the cover of the rod source phantom 932.

Merely by way of example, a cover structure of the cover of the rod source phantom 932 may be a nut structure. Accordingly, the cover opening module 950 may include an automatic nut screwing device based on the nut structure. Therefore, the automatic nut screwing device may automatically open and/or close the cover (i.e., the nut structure) of the rod source phantom 932. In some embodiments, the automatic nut screwing device may be connected with a motor. After the automatic nut screwing device is matched with the cover of the rod source phantom 932, the automatic nut screwing device may be driven to rotate through a rotation of the motor. Therefore, the nut may be screwed out from the rod source phantom 932, thereby opening the cover of the rod source phantom 932. Alternatively, the nut may be tightened to the rod source phantom 932, thereby closing the cover of the rod source phantom 932.

In some embodiments, the third instruction and/or the fourth instruction may be associated with a first operational parameter of the cover opening module 950. In some embodiments, the first operational parameter of the cover opening module 950 may be determined based on a type of the rod source phantom. Exemplary first operational parameters may include an opening and/or closing state of the rod source phantom 932, the opening and/or closing manner of the cover opening module 950, the cover structure of the cover of the rod source phantom 932, etc.

In some embodiments, the liquid level detection module 960 may be configured to receive a fifth instruction sent by the control module 940 when the conveying module 920 transmits the mixed solution, detect a height of a liquid level in the rod source phantom 932 based on the fifth instruction, and send the height of the liquid level to the control module 940. In response to determining that the height of the liquid level exceeds a preset liquid level threshold, the control module 940 may send a sixth instruction to the conveying module 920. The sixth instruction may be used to cause the conveying module 920 to stop the transmission of the mixed solution from the source liquid production module 910 to the rod source phantom 932 in the rod source module 930.

In some embodiments, the liquid level detection module 960 may be disposed at an upper portion of the rod source phantom 932. Therefore, when the cover of the rod source phantom 932 is opened, the liquid level detection module 960 may detect the height of the liquid level in the rod source phantom 932. In some embodiments, the liquid level detection module 960 may include a contact liquid level sensor or a non-contact liquid level sensor. Exemplary liquid level sensors may include an ultrasonic liquid level sensor, a capacitive liquid level sensor, a radar liquid level sensor, or the like, or any combination thereof.

In some embodiments, when the cover of the rod source phantom 932 is opened, the control module 940 may send the fifth instruction to the liquid level detection module 960. In some embodiments, when the rod source phantom 932 is irrigated by the conveying module 920 (i.e., the conveying module 920 transmits the mixed solution from the liquid container 912 to the rod source phantom 932) , the control module 940 may send the fifth instruction to the liquid level detection module 960. In some embodiments, the control module 940 may send the fifth instruction to the liquid level detection component 960 after a preset time period when the irrigation starts. The preset time period may be less than a total time period of the irrigation.

After the liquid level detection component 960 receives the fifth instruction sent by the control module 940, the liquid level detection component 960 may initiate to detect the height of the liquid level, obtain the height of the liquid level of the mixed solution in the liquid container 912, and send the obtained height of the liquid level of the mixed solution to the control module 940 in real time. Therefore, the control module 940 may determine, based on the height of the liquid level and the preset liquid level threshold, whether the height of the liquid level exceeds the preset liquid level threshold. In some embodiments, the preset liquid level threshold may be associated with a size of the rod source phantom 932. That is, rod source phantoms with different sizes may correspond to different preset liquid level thresholds. For example, a corresponding relationship (e.g., a table) between rod source phantoms with different sizes and different preset liquid level thresholds may be stored in the control module 940. Before the rod source phantom 932 is irrigated, a type or a size of the rod source phantom 932 may be input. The control module 940 may determine, based on the input type or size of the rod source phantom 932 and the corresponding relationship, a preset liquid level threshold corresponding to the rod source phantom 932. In some embodiments, the size of the rod source phantom 932 may be determined based on the type of the rod source phantom 932. In some embodiments, the preset liquid level threshold may be determined based on an input of a user. That is, the user may directly determine the height of the liquid level of the mixed solution in the rod source phantom 932.

In some embodiments, the fifth instruction may be associated with a second operational parameter of the liquid level detection component 960. In some embodiments, the second operational parameter of the liquid level detection component 960 may be determined based on the type of the rod source phantom. Exemplary second operational parameters may include a type of the liquid level detection component 960, a detection time, etc.

According to some embodiments of the present disclosure, the rod source phantom irrigation system 900 may be used to automatically open and/or close the cover of the rod source phantom 932. Therefore, no user needs to open and/or close the cover of the rod source phantom 932, which can reduce the irradiation of the radioactive source to the user, reducing the damage to the user, and improve the safety during the rod source irrigation. In addition, the height of the liquid level of the mixed solution in the rod source phantom 932 may be detected in real time, and the irrigation may be automatically stopped based on the height of the liquid level, which can improve the intellectuality of the rod source phantom irrigation system 900. Besides, different preset liquid level thresholds may be used for rod source phantoms with different types and/or sizes, which can improve the accuracy of the automatic irrigation for different types and/or sizes of rod source phantoms, enrich functions of the rod source phantom irrigation system 900, and improve an applicable scope of the rod source phantom irrigation system 900.

The user interaction module 1070 may be in communication with the control module 1040. In some embodiments, the user interaction module 1070 may be configured to obtain a user instruction, and/or display operational data of the rod source phantom irrigation system 1000 and/or prompt information for prompting abnormal information of the rod source phantom irrigation system 1000 to a user. For example, the prompt information may include image data, a code corresponding to the abnormal information, a text describing the abnormal information, or the like, or any combination thereof. The image data may include a barcode, a two-dimensional (2D) code, a compressed image, or the like, or any combination thereof. More descriptions regarding the prompt information may be found elsewhere in the present disclosure (e.g., FIGs. 14-15 and the descriptions thereof) .

In some embodiments, the user interaction module 1070 may include a display screen. Exemplary display screens may include a liquid crystal display (LCD) , an electronic ink display, or the like, or any combination thereof. In some embodiments, the user may control the rod source phantom irrigation system 1400 through the user interaction module 1070. For example, the user may control the source liquid production module 1010, the conveying module 1020, the cover opening module 1050, the liquid level detection module 1060, etc., of the rod source phantom irrigation system 1000 through the user interaction module 1070. For instance, the user may pause and/or stop the mixing by the source liquid production module 1010, pause and/or stop the transmission by the conveying module 1020, etc.

In some embodiments, the user may input a type of the rod source phantom 1032, a preset liquid level height threshold, etc., through the user interaction module 1070. In some embodiments, the user interaction module 1070 may be used to output information for prompting the completion of the irrigation. In some embodiments, the user interaction module 1070 may be used to implement other interactive functions, which are not limited herein.

According to some embodiments of the present disclosure, the rod source phantom irrigation system 1000 may include the user interaction module 1070. The user interaction module 1070 may be in communication with the control module 1040. The interaction between the rod source phantom irrigation system 1000 and the user may be realized through the user interaction module 1070, which can improve the operation convenience of the rod source phantom irrigation system 1000, thereby improving the user experience.

In 1204, a type of the rod source phantom may be selected through a user interaction module.

In 1206, a solvent may be injected into a liquid container.

In 1208, a radioactive source may be injected into the liquid container.

In 1210, the radioactive source and the water may be automatically mixed to obtain a mixed solution.

In 1212, a nut of the rod source phantom may be automatically opened.

In 1214, a liquid level detection module may be moved to a preset position (e.g., an upper portion of the rod source phantom) .

In 1216, a conveying pipe may be controlled to extend into the rod source phantom.

In 1218, the mixed solution may be automatically irrigated into the rod source phantom.

In 1220, the control component may determine whether a height of a liquid level exceeds a preset liquid level threshold. In response to determining that the height of the liquid level does not exceed the preset liquid level threshold, operation 1216 may be proceeded. That is, the mixed solution may be continued to irrigate into the rod source phantom. In response to determining that the height of the liquid level exceeds the preset liquid level threshold, operation 1222 may be proceeded. That is, the irrigation of the mixed solution may be stopped.

In 1224, the conveying pipe may be automatically moved away from the preset position.

In 1226, the nut may be automatically tightened.

In 1228, the completion of the irrigation may be prompted to a user.

It should be noted that the description of the process 1200 is provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the teaching of the present disclosure. However, those variations and modifications may not depart from the protection of the present disclosure.

FIG. 13 is a block diagram illustrating an exemplary processing device 140 according to some embodiments of the present disclosure. In some embodiments, the modules illustrated in FIG. 13 may be implemented on the processing device 140. In some embodiments, the processing device 140 may be in communication with a computer-readable storage medium (e.g., the storage device 150 illustrated in FIG. 1) and may execute instructions stored in the computer-readable storage medium. The processing device 140 may include a determination module 1310 and a generation module 1320.

The determination module 1310 may be configured to determine, based on operational data of a medical system, abnormal information of the medical system. More descriptions regarding the determination of the abnormal information may be found elsewhere in the present disclosure. See, e.g., operation 1402 and relevant descriptions thereof.

The generation module 1320 may be configured to generate prompt information for prompting the abnormal information of the medical system. The prompt information may include image data encoding at least one of the abnormal information or system information of the medical system. More descriptions regarding the generation of the prompt information may be found elsewhere in the present disclosure. See, e.g., operation 1404 and relevant descriptions thereof.

The modules in the processing device 140 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN) , a Wide Area Network (WAN) , a Bluetooth, a ZigBee, a Near Field Communication (NFC) , or the like, or any combination thereof.

It should be noted that the above descriptions of the processing device 140 are provided for the purposes of illustration, and are not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. In some embodiments, the processing device 140 may include one or more other modules. For example, the processing device 140 may include a storage module to store data generated by the modules in the processing device 140. In some embodiments, any two of the modules may be combined as a single module, and any one of the modules may be divided into two or more units.

FIG. 14 is a flowchart illustrating an exemplary process 1400 for prompting an abnormal condition of a medical system according to some embodiments of the present disclosure. Process 1400 may be implemented in the prompting system 100 illustrated in FIG. 1. For example, the process 1400 may be stored in the storage device 150 in the form of instructions (e.g., an application) , and invoked and/or executed by the processing device 140. The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 300 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 1400 as illustrated in FIG. 14 and described below is not intended to be limiting.

In some embodiments, when an abnormal condition of a medical system occurs, a user cannot solve the abnormal condition. Therefore, the user needs to contact a service engineer responsible for the medical system. The service engineer can obtain abnormal information of the medical system provided by the user, so that the service engineer can rush to the scene with repair equipment corresponding to the abnormal condition. Alternatively, the service engineer can remotely control or instruct the user to solve the abnormal condition.

Conventionally, the abnormal information of the medical system may be prompted through a code corresponding to the abnormal information and/or a text describing the abnormal information. However, the text may include related technical terms or types of the abnormal conditions that the user roughly knows, while the code may include only a sequence code corresponding to the abnormal information that the user does not know the meaning of the code. Therefore, the text and the code only can provide insufficient abnormal information for the service engineer. The service engineer needs to perform multiple complex detection procedures on the medical system based on the text description and the code to determine the abnormal condition of the medical system, which prolongs a repair time. In addition, the text and the code are easy to be mistaken, and are difficult to read when transmitted through photography.

In some embodiments, the abnormal information of the medical system can be provided to the service engineer by displaying in text, which partially solves the problem of the insufficient abnormal information. However, a large amount of text may cause confusion and a psychological burden to the user. The large amount of text is easy to be mistaken, and is difficult to read when transmitted through photography. In addition, a size of a display screen of the medical system is required to display the large amount of text, which increases the cost of the medical system. Therefore, the process 300 may be performed to efficiently and accurately prompt the abnormal information of the medical system.

In 1402, the processing device 140 (e.g., the determination module 1310) may determine, based on operational data of a medical system, abnormal information of the medical system.

The operational data may refer to data and/or information of the medical system when the medical system is operating. In some embodiments, the operational data may include a temperature, a humidity, etc., of the medical system (e.g., each component of the medical system 110) , an environmental temperature, an environmental humidity, etc., of a location where the medical system is located, operational efficiency of the medical system, or the like, or any combination thereof. Merely by way of example, if the medical system includes a rod source phantom irrigation system (e.g., the rod source phantom irrigation system 200, the rod source phantom irrigation system 600, the rod source phantom irrigation system 900, the rod source phantom irrigation system 1000, the rod source phantom irrigation system 1100, etc. ) , the operational data may include a first operational parameter of a cover opening module, a second operational parameter of a liquid level detection module, a height of a liquid level obtained by the liquid level detection module, a type and a dose of a radioactive source injected by a source irrigation module into a source liquid production module, a type and a dose of a solvent, a third operational parameter of the source liquid production module, or the like, or any combination thereof.

In some embodiments, the processing device 140 may obtain the operational data of the medical system continuously or intermittently (e.g., periodically) . For example, the medical system 110 (or one or more sensors mounted on the medical system 110) may collect the operational data of the medical system 110 in real-time when the medical system 110 is operating, and the processing device 140 may obtain the operational data of the medical system 110 from the medical system 110 (or the one or more sensors) continuously or intermittently. As another example, the processing device 140 may obtain the operational data of the medical system 110 from a storage device (e.g., the storage device 150, a database, or an external storage device) that stores the operational data of the medical system 110.

The abnormal information may refer to information reflecting that an abnormal condition of the medical system occurs.

In some embodiments, the processing device 140 may determine whether a portion of the operational data of the medical system satisfies a first condition. The first condition may refer to a condition that a portion of the operational data of the medical system is abnormal. In some embodiments, the first condition may include that the temperature of the medical system (or each component of the medical system) exceeds a first temperature threshold, the humidity of the medical system exceeds a first humidity threshold, the environmental temperature exceeds a second temperature threshold, the environmental humidity exceeds a second humidity threshold, the operational efficiency of the medical system does not exceed an efficiency threshold, or the like, or any combination thereof. The first temperature threshold, the first humidity threshold, the second temperature threshold, the second humidity threshold, and/or the efficiency threshold may be determined based on a system default setting or set manually by a user (e.g., a doctor, a technician) .

Merely by way of example, if the medical system includes a rod source phantom irrigation system (e.g., the rod source phantom irrigation system 200, the rod source phantom irrigation system 600, the rod source phantom irrigation system 900, the rod source phantom irrigation system 1000, the rod source phantom irrigation system 1100, etc. ) , the first condition may further include that the first operational parameter exceeds a first operational threshold, the height of the liquid level exceeds a height threshold, the type of the radioactive source does not matched with a preset type of the radioactive source, the dose of the radioactive source does not exceed a preset dose threshold, the second operational parameter exceeds a second operational threshold, the third operational parameter exceeds a third operational threshold, etc.

In some embodiments, in response to determining that a portion of the operational data of the medical system satisfies the first condition, the processing device 140 may determine the portion of the operational data as the abnormal information of the medical system. For example, in response to determining that the temperature of the medical system exceeds the first temperature threshold, the humidity of the medical system exceeds the first humidity threshold, the environmental temperature does not exceed the second temperature threshold, the environmental humidity does not exceed the second humidity threshold, and the operational efficiency of the medical system exceeds the efficiency threshold, the processing device 140 may determine the temperature of the medical system, the humidity of the medical system, and the operational efficiency of the medical system as the abnormal information of the medical system.

In 1404, the processing device 140 (e.g., the generation module 1320) may generate prompt information for prompting the abnormal information of the medical system. The prompt information may include image data encoding at least one of the abnormal information or system information of the medical system.

In some embodiments, the prompt information may include the image data, a code corresponding to the abnormal information, a text describing the abnormal information, or the like, or any combination thereof. The image data may include a barcode, a two-dimensional (2D) code, a compressed image, or the like, or any combination thereof. For example, the 2D code may include a statical 2D code and/or a dynamic 2D code. As another example, the 2D code may include a data matrix, a maxi code, Aztec, a quick response (QR) code, Vericode, PDF417, Ultracode, Code 49, Code 16K, or the like, or any combination thereof.

In some embodiments, the abnormal information may be encoded in the image data. In some embodiments, the 2D code may be generated based on JavaScript Object Notation (JSON) data, which can reduce a count of bytes required to describe same information. Alternatively or additionally, the 2D code may include information encoded based on a preset encoding manner. Exemplary preset encoding manners may include an American standard code for information interchange (ASCII) manner, a Unicode encoding manner (e.g., a GB2312 encoding manner, a GBK encoding manner, a Unicode transformation format (UTF-8) encoding manner, etc. ) , or the like, or any combination thereof.

In some embodiments, the prompt information needs include enough information for a target user (e.g., a service engineer) to determine the abnormal condition of the medical system. For example, information entropy of the image date in the prompt information may exceed a preset bit threshold. The information entropy may refer to information entropy in Shannon’s “Information Theory. ” In some embodiments, if a count of the possibility corresponding to the image data is “N, ” the information entropy of the image date may be “log ₂N. ”

In some embodiments, the preset bit threshold may be determined based on a system default setting or set manually by the user. For example, the preset bit threshold may be 1024 bits. When the preset bit threshold is 1024 bits, a transmission efficiency of the image date in the prompt information may be larger than a transmission efficiency of the text describing the abnormal information. For instance, 1024 bits may correspond to 64 Chinese characters, which can improve an amount of the prompt information. It should be noted that, setting the preset bit threshold as 1024 bits is an example, and 1024 bits is a minimum value of the preset bit threshold.

Merely by way of example, when the image data is a 2D code, the image data may include 500 Chinese characters, which can be enough to provide the prompt information. In some embodiments, when the prompt information is encoded based on the preset encoding manner, the amount of the prompt information may be improved.

As another example, the processing device 140 may determine a count of bits corresponding to the prompt information. In response to determining that the count of bits corresponding to the prompt information is less than a capacity of a static 2D code, the processing device 140 may encode the prompt information in the static 2D code. In response to determining that the count of bits corresponding to the prompt information is equal to or larger than the capacity of the static 2D code, the processing device 140 may encode the prompt information in the dynamic 2D code.

In some embodiments, system information of the medical system may be encoded in the image data. For example, the system information of the medical system may be encoded in the image data based on the preset encoding manner. In some embodiments, the preset encoding manner corresponding to the system information of the medical system may be the same as or similar to the preset encoding manner corresponding to the abnormal information.

In some embodiments, the system information may include a serial number of the medical system, an information prompting time, a current software version of the medical system, a calibration time of the medical system, a current state of the medical system, log information of the medical system in a preset time period, code information related to the abnormal information, turn-on information of the medical system, turn-off information of the medical system, or the like, or any combination thereof.

The serial number of the medical system may refer to an identify number of the medical system. Each medical system may correspond to a unique serial number. Therefore, the medical system including the abnormal condition may be determined based on the serial number of the medical system.

The information prompting time may refer to a time when the prompt information is generated. For example, when the prompt information is generated, the information prompting time may be determined.

The current software version of the medical system may refer to a software version of an application operated on the medical system.

The calibration time of the medical system may refer to a time when the medical system is calibrated previously. For example, when the medical system is calibrated, the calibration time of the medical system may be updated.

The current state of the medical system may refer to a state of the medical system when the abnormal condition of the medical system occurs. For example, if the medical system is imaging a subject when the abnormal condition of the medical system occurs, the current state of the medical system may be determined as an operating state. As another example, if the medical system is pending when the abnormal condition of the medical system occurs, the current state of the medical system may be determined as a pending state. As still another example, if the medical system is shutdown when the abnormal condition of the medical system occurs, the current state of the medical system may be determined as a shutdown state.

The log information of the medical system in the preset time period may refer to information of one or more operations that the medical system performed in the preset time period. The preset time period may be determined based on a system default setting or set manually by the user, e.g., a time period from ten minutes before the abnormal condition occurs to a time point when the abnormal condition occurs.

The code information related to the abnormal information may refer to descriptions of the code corresponding to the abnormal information. In some embodiments, the code information related to the abnormal information may include a text describing the abnormal information, a solution for processing the abnormal condition, or the like, or any combination thereof. The solution for processing the abnormal condition may include an analysis of the abnormal condition, a candidate tool for processing the abnormal condition, a processing operation, or the like, or any combination thereof. In some embodiments, the solution for processing the abnormal condition may be stored in a storage, and the processing device 140 may obtain the solution by retrieving the storage. For example, different candidate solutions may be determined for different abnormal conditions (or different abnormal information) , and the processing device 140 may determine the solution from the candidate solutions based on the abnormal condition (or the abnormal information) . As another example, the processing device 140 may determine the solution based on the abnormal condition (or the abnormal information) and historical data including historical abnormal conditions and historical solutions.

The turn-on information of the medical system may refer to information relating to a turn-on operation of the medical system. In some embodiments, the turn-on information may include a last time point when the medical system is turned on, a time period that the medical system spent on the last turn-on operation, etc.

The turn-off information of the medical system may refer to information relating to a turn-off operation of the medical system. In some embodiments, the turn-off information may include a last time point when the medical system is turned off, a time period that the medical system spent on the last turn-off operation, a last time point when the medical system is power-off, etc.

In some embodiments, the prompt information may further include the code corresponding to abnormal information and/or the text describing the abnormal information. The code corresponding to the abnormal information may include a sequence code representing the abnormal information. For example, a corresponding relationship (e.g., a table) between a plurality of codes and abnormal information. The text may describe the abnormal information. For example, the text may include related technical terms or types of the abnormal conditions.

Since the abnormal information and/or the system information of the medical system are encoded in the image data, the user may obtain the abnormal information and/or the system information of the medical system through a decoder (e.g., a mobile phone) . Alternatively, the user may transmit the abnormal information and/or the system information of the medical system through a photography device (e.g., a camera) . By providing the code corresponding to abnormal information and/or the text describing the abnormal information, the prompt information may be provided to the user visually. Therefore, the user may provide a portion of the prompt information without the decoder or the photography device.

Merely by way of example, referring to FIG. 15, FIG. 15 is a schematic diagram illustrating an exemplary prompt information according to some embodiments of the present disclosure.

As shown in FIG. 15, prompt information may include a 2D code 402, a code 1504 corresponding to abnormal information, and a text 1506 describing the abnormal information. For example, when a medical system detects that a humidity of the medical system exceeds the first humidity threshold, prompt information may be generated. The prompt information may include the 2D code 1502, the code 1504 (i.e., “P00001” ) corresponding to the abnormal information, and the text 1506 that prompts “Humidity of the medical system exceeds the first humidity threshold, please detect the environmental humidity. ”

In some embodiments, the system information may include fixed information and variable information. The fixed information may refer to information that is fixedly encoded in the image data. The variable information may refer to information that is variably encoded in the image data.

In some embodiments, a portion of the system information may be described in a little amount of text and be helpful for the analysis of the abnormal condition. Therefore, the portion of the system information may be determined as a fixed content (i.e., the fixed information) of the image data. Exemplary fixed information may include the serial number of the medical system, the information prompting time, the current software version, the calibration time of the medical system, the code information, the turn-on information of the medical system, the turn-off information of the medical system, or the like, or any combination thereof.

In some embodiments, a portion of the system information may be described in a large amount of content, and not all the portion of the system information may be helpful for the analysis of the abnormal condition. Therefore, the portion of the system information may be determined as a variable content (i.e., the variable information) of the image data. Exemplary variable information may include the current state of the medical system and/or the log information of the medical system in the preset time period.

Since the amount of the image data is fixed, the processing device 140 may determine the variable information before the prompt information is generated by encoding the abnormal information and/or the system information.

In some embodiments, the processing device 140 may determine, based on the abnormal information, the variable information. For example, the processing device 140 may determine, based on the abnormal information, an error reporting component of the medical system. The error reporting component may refer to a component including an abnormal condition. For example, in response to determining that a temperature of a component in the medical system exceeds the first temperature threshold, the processing device 140 may determine the component as the error reporting component of the medical system. Further, the processing device 140 may determine, based on information of the error reporting component, the variable information. The information of the error reporting component may include log information of the error reporting component, a current state of the error reporting component, or the like, or any combination thereof. For instance, the processing device 140 may designate the information of the error reporting component as a portion of the variable information.

As another example, the processing device 140 may determine an associated component of the error reporting component in the medical system based on the abnormal information. The associated component may be a component associated with the error reporting component. For instance, the associated component may include a component connected to the error reporting component, a component around the error reporting component, or the like, or any combination thereof. The processing device 140 may determine, based on information of the associated component, the variable information. The information of the associated component may include log information of the associated component, a current state of the associated component, or the like, or any combination thereof. For instance, the processing device 140 may designate the information of the associated component as a portion of the variable information.

In some embodiments, the processing device 140 may determine the variable information using an importance degree prediction model. For example, the processing device 140 may obtain candidate variable information including the current state of the medical system and the log information of the medical system in the preset time period. The processing device 140 may determine, based on the abnormal information, an importance degree of the candidate variable information using the importance degree prediction model. The importance degree prediction model may be a machine learning model. Further, the processing device 140 may select, based on the importance degree, the variable information from the candidate variable information. More descriptions regarding the determination of the variable information using the importance degree prediction model may be found elsewhere in the present disclosure (e.g., FIG. 16 and the descriptions thereof) .

In some embodiments, the processing device 140 may encode the fixed information and the variable information in the image data. For example, the fixed information and the variable information may be encoded in the image data based on a preset encoding manner.

In some embodiments, the processing device 140 may receive an information acquisition instruction for requesting specific information of the medical system. The specific information may be used for the analysis of the abnormal condition. In some embodiments, the user may input the information acquisition instruction through a user interface. For example, the user may input the information acquisition instruction, through a keyboard, a mouse, a touch screen, etc.

In some embodiments, the processing device 140 may generate, based on the information acquisition instruction, the image data to encode the requested specific information of the medical system. For example, the processing device 140 may determine, based on the information acquisition instruction, the requested specific information of the medical system from the abnormal information and/or the system information, and generate the image data by encoding the requested specific information of the medical system.

In some embodiments, the processing device 140 may display the prompt information through a user interface of the medical system (e.g., a user interface module 1070) .

In some embodiments, the prompt information may be transmitted to a target user (e.g., a service engineer) . For example, the processing device 140 may transmit the prompt information to a terminal of the target user, and the target user may obtain the prompt information through a user interface of the terminal. As another example, the user may acquire an image including the prompt information through photography, and transmit the image to the target user (e.g., a terminal of the target user) . By obtaining the image including the prompt information, the prompt information may be retained in the image, which can reduce a difficulty of the transmission of the prompt information. In some embodiments, a portion of the prompt information may be used for error correction, which can reduce a possibility that the prompt information is lost during the transmission.

In some embodiments, the photography may refer to a manner of copying with light (or electromagnetic waves) as an intermediary. The photography may include shooting, scanning, copying, etc., that can reproduce a content of the prompt information but may distort the prompt information during the copying process.

In some embodiments, before the prompt information is transmitted to the target user, the processing device 140 may determine the target user from one or more candidate users. For example, the processing device 140 may determine the target user from one or more candidate users based on the prompt information. For instance, when the prompt information corresponds to a seriously and urgently abnormal condition of the medical system, the processing device 140 may determine a candidate user who has time to process the abnormal condition immediately as the target user. When the prompt information corresponds to a non-urgently abnormal condition, the processing device 140 may determine a candidate user who is good at processing the abnormal condition as the target user. In some embodiments, the processing device 140 may directly transmit the prompt information to the target user when the abnormal condition of the medical system is serious and urgent.

In some embodiments, after the target user obtains the prompt information, the target user may decode the prompt information to obtain the abnormal information and/or the system information. For example, the prompt information may be decoded through a decoder. In some embodiments, the decoding manner may correspond to the encoding manner. For example, if the abnormal information and/or the system information are encoded through a Unicode encoding manner, the prompt information may be decoded through a Unicode decoding manner.

In some embodiments, the decoder may be the same as or different from the terminal of the target user. For example, the target user may obtain the prompt information and decode the prompt information through a mobile phone. As another example, the target user may obtain the prompt information through a computer, and decode the prompt information through a mobile phone.

According to some embodiments of the present disclosure, the abnormal information of the medical system may be determined based on the operational data of the medical system, and the prompt information for prompting the abnormal information of the medical system may be generated, which can provide enough information for the target user to determine the abnormal condition of the medical system when the target user does not arrive on site, thereby improving the accuracy and efficiency of the determination of the abnormal condition. By determining the abnormal condition of the medical system, the target user may arrive at the scene with repair equipment corresponding to the abnormal condition. Alternatively, the target user may remotely control or instruct the user to solve the abnormal condition, which can improve the accuracy and efficiency of the solving of the abnormal condition. In addition, the prompt information may be generated through an encoding manner, which can reduce a possibility that the prompt information is lost during the transmission, thereby improving the accuracy of the prompt information during the transmission.

It should be noted that the description of the process 1400 is provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the teaching of the present disclosure. However, those variations and modifications may not depart from the protection of the present disclosure.

FIG. 16 is a flowchart illustrating an exemplary process 1600 for selecting variable information from candidate variable information according to some embodiments of the present disclosure. In some embodiments, the process 1600 may be performed to achieve at least part of operation 1404 as described in connection with FIG. 14.

In 1602, the processing device 140 (e.g., the determination module 1310) may obtain candidate variable information including a current state of a medical system and log information of the medical system in a preset time period.

The candidate variable information may refer to information that is described in a large amount of content, and cannot be helpful for the analysis of an abnormal condition of the medical system. In some embodiments, the processing device 140 may obtain the current state of the medical system and the log information of the medical system in the preset time period as the candidate variable information.

In some embodiments, the processing device 140 may obtain the current state of the medical system and the log information of the medical system in the preset time period from the medical system 110 or a storage device (e.g., the storage device 150, a database, or an external storage device) that stores the current state of the medical system and the log information of the medical system in the preset time period. Accordingly, the processing device 140 may determine the current state of the medical system and the log information of the medical system in the preset time period as the candidate variable information.

In 1604, the processing device 140 (e.g., the determination module 1310) may determine, based on abnormal information, an importance degree of the candidate variable information using an importance degree prediction model. The importance degree prediction model may be a machine learning model.

The importance degree may refer to a degree of influence of the candidate variable information on analyzing the abnormal condition of the medical system. The larger the importance degree, the higher the degree of influence of the candidate variable information on analyzing the abnormal condition of the medical system.

In some embodiments, the candidate variable information may be input into the importance degree prediction model, and the importance degree prediction model may output the importance degree of the candidate variable information.

In some embodiments, the importance degree prediction model may include an embedding layer and an importance degree determination layer.

In some embodiments, a first input of the embedding layer may include the candidate variable information, and a first output of the embedding layer may include at least one information segment of the candidate variable information. An information segment of the candidate variable information may refer to a portion of information obtained by segmented the candidate variable information according to a dividing standard (e.g., a content of the candidate variable information, a time of the candidate variable information, a type of the candidate variable information, etc. ) . For example, the current state of the medical system may be segmented into at least one information segment based on information types. As another example, the log information of the medical system in the preset time period may be segmented into at least one information segment based on different components of the medical system.

A second input of the importance degree determination layer may include code information and the at least one information segment, and a second output of the importance degree determination layer may include an importance degree of each of the at least one information segment. For example, the importance degree determination layer may determine a relevance degree between each of the at least one information segment and the code information, and designate the relevance degree of each of the at least one information segment as the importance degree of each of the at least one information segment.

In some embodiments, the importance degree prediction model may be obtained by training an initial model based on a plurality of training samples. In some embodiments, each of the plurality of training samples may include a sample current state of a sample medical system, sample log information of the sample medical system in the preset time period, and sample code information as an input of the initial model, and a sample importance degree of each of at least one sample information segment of the sample current state and the sample log information as a label. In some embodiments, the sample importance degree may be manually labelled. For the sample current state, the sample importance degree may be labelled on each information type of the sample current state. For the sample log information, the sample importance degree may be labelled on each portion of the sample log information corresponding to each component of the sample medical system.

The obtaining of the sample current state of the sample medical system, the sample log information of the sample medical system in the preset time period, and the sample code information may be similar to the obtaining of the system information described in operation 1404. In some embodiments, the processing device 140 may obtain the plurality of training samples by retrieving (e.g., through a data interface) a database or a storage device.

During the training of the initial model, the plurality of training samples may be input to the initial model, and parameter (s) of the initial model may be updated through one or more iterations. For example, the processing device 140 may input the sample current state of the sample medical system, the sample log information of the sample medical system in the preset time period, and the sample code information of each training sample into the initial model, and obtain a prediction result. The processing device 140 may determine a loss function based on the prediction result and the label (i.e., the sample importance degree of each of the at least one sample information segment of the sample current state and the sample log information) of each training sample. The loss function may be associated with a difference between the prediction result and the label. The processing device 140 may adjust the parameter (s) of the initial model based on the loss function to reduce the difference between the prediction result and the label, for example, by continuously adjusting the parameter (s) of the initial model to reduce or minimize the loss function.

In some embodiments, the loss function may be a perceptual loss function, a squared loss function, a logistic regression loss function, etc.

In some embodiments, the importance degree prediction model may also be obtained according to other training manners. For example, the importance degree prediction model may be obtained based on an initial learning rate (e.g., 0.1) and/or an attenuation strategy using the plurality of training samples.

In 1606, the processing device 140 (e.g., the determination module 1310) may select, based on the importance degree, variable information from the candidate variable information.

For example, the processing device 140 may rank the at least one information segment based on the importance degree, and select top N information segments from the candidate variable information as the variable information.

According to some embodiments, the variable information may be selected from the candidate variable information using the importance degree prediction model, which can improve the efficiency of the determination of the variable information, thereby improving the efficiency of the generation of the prompting information.
