Description

  The present invention relates to a chemical solution injector that injects a chemical solution to a subject whose fluoroscopic image data is captured, and more particularly to a chemical solution injector that functions as part of a fluoroscopic imaging system.

  Currently, as a fluoroscopic imaging apparatus that captures a tomographic image that is a fluoroscopic image data of a subject, a CT (Computed Tomography) scanner, an MRI (Magnetic Resonance Imaging) apparatus, a PET (Positron Emission Tomography) apparatus, an ultrasonic diagnostic apparatus, and the like is there. In addition, as a fluoroscopic imaging apparatus that captures a blood vessel image that is a fluoroscopic image data of a subject, there are a CT angio apparatus, an MRA (MR Angio) apparatus, and the like.

  When using the fluoroscopic imaging apparatus as described above, a chemical solution such as a contrast medium or physiological saline may be injected into a subject, and a chemical solution injection apparatus that automatically executes this injection has also been put into practical use. A general chemical solution injection device holds a chemical solution syringe filled with a chemical solution, and injects a chemical solution into a subject by press-fitting a piston member into the cylinder member.

  Although the fluoroscopic imaging device functions as a stand-alone, normally, a fluoroscopic imaging system including part of the fluoroscopic imaging device is constructed. Such a fluoroscopic imaging system includes, for example, a chart management device, an imaging management device, a fluoroscopic imaging device, a data storage device, an image browsing device, and the like.

  The medical chart management apparatus is generally called a HIS (Hospital Information System) or the like, and manages a so-called electronic medical chart. This electronic medical record is created for each subject.

  For example, when fluoroscopic image data is imaged from a subject, imaging order data is created by the medical record management device based on the electronic medical record of the subject. This imaging order data is generated for each imaging operation in which fluoroscopic image data is imaged from the subject.

  More specifically, the imaging order data includes, for example, imaging work ID (Identity) which is unique identification information, identification information of the fluoroscopic imaging device, identification information of the subject, date and time of imaging start and end, and the like.

  Such imaging order data is supplied from the chart management apparatus to the imaging management apparatus. The imaging management apparatus is generally called RIS (Radiology Information System) or the like, and manages imaging order data for imaging fluoroscopic image data from a subject.

  The fluoroscopic imaging apparatus acquires imaging order data from the imaging management apparatus and executes an imaging operation. In that case, in the fluoroscopic imaging apparatus, fluoroscopic image data is captured from the subject corresponding to the imaging order data. The fluoroscopic image data is output with at least a part of the imaging order data by the fluoroscopic imaging device to the data storage device.

  This data storage device is generally called a PACS (Picture Archive and Communication System) or the like, and stores fluoroscopic image data to which imaging order data is added.

  An image browsing device generally called a viewer is connected to the data storage device. For example, the image browsing apparatus reads the fluoroscopic image data using the imaging order data as a search key, and displays the fluoroscopic image data.

  However, the imaging management apparatus normally manages a plurality of imaging order data. For this reason, it is necessary to selectively provide one to the fluoroscopic imaging device from a plurality of imaging order data managed by the imaging management device. Therefore, there are types of imaging management apparatuses called push type and pull type.

  The push-type imaging management device selects one from a plurality of managed imaging order data, for example, by manual operation of an operator. When the push-type imaging management apparatus receives an acquisition request for imaging order data from the fluoroscopic imaging apparatus, it returns one selected imaging order data.

  The pull-type imaging management apparatus transmits an order search key together with an acquisition request for imaging order data from the fluoroscopic imaging apparatus. The order search key is made up of, for example, an imaging work ID of imaging order data.

  Therefore, the imaging management apparatus searches the imaging order data with the order search key, and returns the searched imaging order data to the fluoroscopic imaging apparatus. When one appropriate imaging order data is returned, the fluoroscopic imaging apparatus captures fluoroscopic image data from the subject corresponding to the imaging order data.

  On the other hand, when a plurality of imaging order data is retrieved and returned, the fluoroscopic imaging apparatus selects one of the received plurality of imaging order data by, for example, a manual operation by an operator.

  Note that, when the imaging order data transmitted from the imaging management apparatus as described above is determined by the fluoroscopic imaging apparatus, this is notified to the imaging management apparatus. For this reason, even in the pull-type imaging management apparatus, one imaging order data used for imaging fluoroscopic image data by the fluoroscopic imaging apparatus is specified.

There are various proposals for the fluoroscopic imaging system as described above (see, for example, Patent Documents 1 and 2).

  More specifically, in the liquid injector 400, “head, chest, abdomen, legs” are defined as a plurality of body sections, and schematic images corresponding to each of these are registered in the computer unit 405. Yes.

  Therefore, when a predetermined operation is performed on the chemical solution injector 400, a schematic image of “head, chest, abdomen, legs” is displayed and output on the upper part of the screen of the touch panel 403 as shown in FIG. The

  In addition, in the schematic image of the “head” that is the above-described body classification, schematic images such as “brain part, jaw part, and neck part” are registered in association with each other as a plurality of imaging parts. Similarly, the “chest” image is “heart, lung”, the “abdomen” image is “stomach, liver,…”, and the “leg” image is “upper, lower”. ”And the like are registered in association with each other.

  Therefore, when one of the schematic images of the plurality of body ranges displayed and output on the touch panel 403 in the form of a human body is manually operated, the schematic image of the scanner mechanism is displayed and output only above the one schematic image, and is manually operated. Only one schematic image turns bright and the other schematic image turns dark (not shown).

  At the same time, a schematic image of a plurality of related imaging parts is displayed and output at the lower part. Therefore, when one of the schematic images of the plurality of imaging parts displayed and output is manually operated, as shown in FIG. 9, only the one schematic image is turned bright and the other schematic images are turned dark.

  The condition storage unit 441 stores operation condition data of the syringe drive mechanisms 411 and 412 for each of a large number of imaging parts of the human body.

  The medicinal solution storage unit 443 stores the content concentration of iodine, which is a contained component, as a medicinal solution item related to imaging of fluoroscopic image data for each product name that is a type of a plurality of contrast agents. That is, the chemical solution injection device 400 can use a plurality of types of contrast agents, but the contrast concentrations of the contrast agents differ for each product.

  When injecting a contrast medium into a subject and imaging fluoroscopic image data, the contrast level is different if the iodine concentration is different. Therefore, in the chemical solution injector 400, the iodine concentration is registered for each product name of the contrast medium.

  The chemical liquid display unit 452 displays and outputs the product names of a plurality of contrast agents stored in the chemical liquid storage unit 443. The drug solution input unit 453 receives an input operation for selecting one of the types of contrast medium displayed and output by the drug solution display unit 452 as an input operation for one injection condition data. The chemical liquid reading unit 454 reads the iodine concentration corresponding to the type of contrast agent selected by the chemical liquid input unit 453, and sets it in the injection control unit 422 as a part of the injection condition data.

  More specifically, when the imaging region is selected by manual operation of the schematic image as described above and the operation icon “condition” is manually operated, the weight, the product name of the contrast medium, the injection volume, and the injection It will be in the state where input operation such as time can be performed.

  Therefore, in such a state, a numerical value of weight is input and a product name is selected from a pull-down menu. Then, as shown in FIG. 10, these are displayed and set as part of the injection condition data.

  The start instructing unit 421 receives an input operation for injecting the injection using the touch panel 403 of the injection control unit 401 or the like in a state where the injection condition data is set as described above. When the injection start is input as described above, the injection control unit 422 controls the operation of the syringe drive mechanisms 411 and 412 corresponding to the set injection condition data.

  The above-described units 446 to 453 are used when manually inputting all of the injection condition data as described above. However, the chemical injection device 400 of the present embodiment can automatically input a part or all of the injection condition data by the following units 423 to 427 and the like.

  More specifically, the acquisition instruction unit 423 of the chemical liquid injector 400 accepts an input operation of an injection condition data acquisition request. The setting acquisition unit 424 transmits an acquisition operation that has been input to the control box 500, and acquires a part of the imaging order data returned from the control box 500 as condition setting data. The injection setting unit 427 sets a part of the condition setting data acquired as described above in the injection control unit 422 as injection condition data.

  More specifically, as shown in FIG. 8, on the touch panel 403 of the injection control unit 401, for example, a schematic diagram of the front image of the human body and “i” on the upper left of the initial screen of the input operation of the injection condition data. The operation icon for the acquisition request consisting of is displayed and output.

  Therefore, when the operation icon for this acquisition request is input, a part of the imaging order data is acquired as condition setting data via the control box 500. Then, from this condition setting data, the imaging region, the body weight, the type of contrast agent, and the like are set in the injection control unit 422 as at least part of the injection condition data.

  At this time, if the imaging site is included in the injection condition data as described above, the injection setting unit 427 causes the operation reading unit 449 to read out the operation condition data, and as a part of the injection condition data, the injection control unit 422 is set.

  The confirmation instructing unit 428 receives a final confirmation input operation immediately before the injection by the final confirmation switch 414 of the injection execution head 410. The confirmation acquisition unit 429 acquires condition setting data from the RIS 100 again when the final confirmation is input.

  The coincidence confirmation unit 431 confirms the coincidence between the condition setting data acquired again and the condition setting data set in the injection control unit 422. The injection restricting unit 432 prohibits the operation control of the syringe drive mechanisms 411 and 412 by the injection control unit 422 until this coincidence is confirmed.

  That is, in the state where the injection condition data is set in the injection control unit 422 by manual operation as described above, the syringe drive mechanisms 411 and 412 start to be driven when an input of injection start is performed.

  However, when the injection condition data is automatically set from the imaging order data as described above, the driving of the syringe drive mechanisms 411 and 412 is prohibited, and this prohibition includes the set condition setting data and the condition setting data acquired again. It will not be released unless the match is confirmed.

  The history generation unit 433 of the chemical solution injection device 400 corresponds to a function of the computer unit 405 executing a predetermined process corresponding to a computer program, and generates injection history data in which a history of chemical solution injection is recorded.

  The injection history data generated in this way is, for example, text data such as an injection work ID that is unique identification information for each injection work, one of the horizontal axis and the vertical axis is elapsed time, and the other is the time of injection speed. Consists of graph image data.

  In the above-described injection history data, it is also recorded whether all of the injection condition data is set by manual operation or part of the acquired imaging order data is set. Further, when a part of the injection condition data is set by the imaging order data, the date and time when the imaging order data was acquired and the date and time when it was acquired and confirmed again are recorded.

  The history output unit 434 of the chemical solution injector 400 corresponds to a function of the computer unit 405 performing data communication by the communication I / F 406 and transmits the generated injection history data to the control box 500.

  As shown in FIG. 3, the control box 500 according to the present embodiment includes a computer unit 501, a communication I / F 502, and the like on which a dedicated computer program is mounted.

  Also in the control box 500, the computer unit 501 executes various processes corresponding to the computer program. Therefore, in the control box 500, as shown in FIG. 2, each unit such as the acquisition mediation unit 511 and the history transfer unit 514 is logically realized as various functions.

  In response to the acquisition request received from the chemical liquid injector 400, the acquisition mediation unit 511 acquires imaging order data from the RIS 100, and the chemical liquid injector 400 uses a part of the acquired imaging order data as part of the injection condition data. Reply to The history transfer unit 514 receives the injection history data from the chemical solution injection device 400 and transfers it to the PACS 300.

  Therefore, the PACS 300 according to the present embodiment not only stores the fluoroscopic image data received from the CT scanner 200 as described above, but also stores the injection history data received from the control box 500 as described above.

  As described above, the imaging order data is assigned to the fluoroscopic image data, and the imaging work ID of the imaging order data is assigned to the injection history data. Therefore, the imaging order data and the injection history data are stored in the PACS 300 in a state where they are associated with each other by the imaging work ID.

  The image browsing apparatus 600 according to the present embodiment is also a computer apparatus in which a dedicated computer program is installed. As shown in FIG. 3, the image browsing apparatus 600 includes a computer unit 601, a display unit 602, a controller unit 603, a communication I / F 604, and the like.

  The image browsing apparatus 600 includes a data reading unit 611 and a data display unit 612 as shown in FIG. 2 when the computer unit 601 executes various processes corresponding to the computer program.

  The data reading unit 611 corresponds to, for example, a function in which the computer unit 601 accesses the PACS 300 from the communication I / F 604 corresponding to the computer program and input data to the controller unit 603, and is associated with the imaging work ID. The fluoroscopic image data and the injection history data are read from the PACS 300.

  The data display unit 612 corresponds to a function of causing the display unit 602 to display the received data of the communication I / F 604 on the computer unit 601 and displays the read fluoroscopic image data and injection history data.

  Note that the computer program of the RIS 100 as described above manages, for example, imaging order data for imaging fluoroscopic image data from a subject with unique identification information, and a plurality of imaging orders corresponding to an operator's input operation. It is described as software for causing the RIS 100 to select one of the data, return one selected imaging order data in response to an acquisition request received from the CT scanner 200 or the control box 500, and the like. Has been.

  Further, the computer program of the CT scanner 200 transmits, for example, an imaging order data acquisition request to the RIS 100 in response to an input operation by the operator, receives imaging order data returned from the RIS 100, and receives the received imaging. The operation of the fluoroscopic imaging unit 201 is controlled according to the order data, the imaging order data is added to the fluoroscopic image data captured by the fluoroscopic imaging unit 201, and the fluoroscopic image data with the imaging order data is transmitted to the PACS 300. The software is described as software for causing the imaging control unit 210 to execute.

  Further, the computer program of the chemical solution injector 400, for example, causes a schematic image of a plurality of registered body sections to be displayed and output on the touch panel 403 corresponding to the shape of the human body, and from the plurality of body sections displayed as images. Receiving an input operation to the touch panel 403 for selecting one, displaying and outputting a schematic image of at least one imaging region corresponding to the selected body segment, and an input operation for selecting the imaging region displayed as the image , Reading operation condition data corresponding to the selected imaging region, accepting input operations such as body weight and type of contrast medium, and operating condition data, body weight and type of contrast medium as injection condition data Set, accepting an input operation for starting injection, set when an input operation is performed for starting injection Controlling the operation of the syringe drive mechanisms 411 and 412 in response to the injection condition data, causing the operation icon for the acquisition request to be displayed on the touch panel 403, and transmitting the acquisition request to the control box 500 when the operation icon is input. Setting condition setting data consisting of a part of the imaging order data returned from the control box 500 in response to the acquisition request as a part of the injection condition data, and using the acquired imaging order data as the injection condition data Is set, the operation control of the syringe drive mechanisms 411 and 412 is prohibited, and the final confirmation input operation immediately before the injection by the final confirmation switch 414 is accepted with the injection condition data set in the acquired imaging order data. When the final confirmation is input, the condition setting data can be acquired again. Confirming the match between the acquired condition setting data and the set condition setting data, canceling the prohibition of the operation control of the syringe drive mechanisms 411 and 412 when this match is confirmed, Thus, it is described as software for causing the computer unit 405 to execute injection history data including a time-lapse graph, to transmit the generated injection history data to the control box 500, and the like.

  In the chemical solution injection device 400, resources used for the computer program as described above are also registered. This resource includes, for example, a data file that associates a schematic image of a plurality of body segments of a human body with a schematic image of a large number of imaging regions, and operating condition data of syringe drive mechanisms 411 and 412 for each of a large number of imaging regions of a human body. It consists of a data file, a data file of iodine concentration for each product name of a plurality of contrast agents, and the like.

  Further, the computer program of the control box 500 receives, for example, injection history data from the chemical injection device 400, transmits an imaging order data acquisition request to the RIS 100 when the injection history data is received, and is returned from the RIS 100. Receiving imaging order data, giving imaging work ID, which is individual identification information of imaging order data, to injection history data, outputting injection history data assigned with imaging work ID to PACS 300, etc. It is described as software for causing the computer unit 501 to execute.

  The computer program of the PACS 300 receives, for example, the fluoroscopic image data to which the imaging order data is assigned from the CT scanner 200 and stores it, and the injection history data to which the imaging work ID of the imaging order data is assigned to the control box 500. The software is described as software for causing the PACS 300 to execute reception and storage from the PACS 300.

  Then, for example, the computer program of the image browsing apparatus 600 reads the fluoroscopic image data and the injection history data associated with the imaging work ID from the PACS 300, and displays the read fluoroscopic image data and the injection history data. And the like are described as software for causing the computer unit 601 to execute the above.

  A method for imaging fluoroscopic image data from a subject using the fluoroscopic imaging system 1000 of the present embodiment in the configuration as described above will be described in order below. First, the operator registers imaging order data in the RIS 100 in advance.

  The imaging order data includes, for example, text data such as an imaging work ID, identification information of the CT scanner 200, imaging start and end dates and times, an imaging part, and the like. This imaging order data is usually created based on an electronic medical record for each subject.

  Therefore, identification information, name, weight, and the like of the subject are registered in the imaging order data. Furthermore, in the present embodiment, the name and product number of the contrast agent to be used, the type and size of the injection needle used for the injection of the contrast agent, and the like are also registered.

  However, the imaging order data is composed of various data necessary for the imaging operation with the CT scanner 200. For this reason, the data which can specify the injection | pouring operation | work of the chemical | medical solution injection apparatus 400 are not included.

  When an imaging operation is executed in a state where such imaging order data is registered in the RIS 100, one imaging order data corresponding to the imaging operation is selected by the operator manually operating the RIS 100.

  On the other hand, in the field of imaging work, as shown in FIG. 4, a chemical solution injector 400 is disposed in the vicinity of the fluoroscopic imaging unit 201 of the CT scanner 200. A chemical syringe 430 is connected to a subject (not shown) located in the fluoroscopic imaging unit 201 with an extension tube, and the chemical syringe 430 is loaded into the injection execution head 410 of the chemical injector 400.

  Next, as shown in FIG. 13, when the operator activates the chemical injection device 400 by an input operation of the main operation unit 402 of the injection control unit 401 (step S1), as shown in FIG. A schematic image of a plurality of body sections is displayed corresponding to the human body shape (step S2).

  In the chemical injection device 400 of the present embodiment, operation control of the syringe drive mechanisms 411 and 412 based on the injection condition data is prohibited in the initial state where the injection condition data is not set.

  And the chemical | medical solution injection | pouring apparatus 400 can also set all of injection | pouring condition data manually with the initial screen displayed as mentioned above, and can also set the one part automatically from imaging order data.

  In the case of manual setting, the operator presses one of the schematic images of the plurality of body sections displayed on the touch panel 403 with a finger. Then, only the schematic image of the selected body section is highlighted and the other schematic images are darkened, and the schematic image of the scanner mechanism is displayed above the schematic image of the selected body section.

  At the same time, schematic images of a plurality of imaging regions related to the selected body section are read out below and displayed on the selection screen. Therefore, when the operator performs an input operation with one finger or the like, as shown in FIG. 9, only the selected one schematic image is highlighted and the other schematic images are darkened.

  When an imaging region is selected as described above, in the chemical solution injector 400, operation condition data corresponding to the imaging region is read and set as injection condition data. Further, the operator's body weight, chemical identification information, injection speed, total injection amount, injection time, etc. are input to the main operation unit 402 by the operator as injection condition data (step S4).

  When the setting of the injection condition data is completed by the input operation as described above (steps S5 and S6), it becomes possible to input the start of injection by the touch panel 403. Accordingly, when this injection start is input (step S7), the syringe drive mechanisms 411 and 412 are controlled in response to the set injection condition data, so that the subject can be contrasted with saline and physiological saline. Is injected properly.

  In the fluoroscopic imaging system 1000 of the present embodiment, the injection condition data can be automatically set in addition to being manually set in the chemical liquid injector 400 as described above. More specifically, in the chemical injection device 400 of the present embodiment, as shown in FIG. 8, an operation icon for an acquisition request is also displayed on the upper left of the initial screen of the injection operation.

  Therefore, when the operation icon for the acquisition request is manually operated (step S3), the acquisition request is transmitted to the control box 500 as shown in FIG. The control box 500 transfers the acquisition request received from the chemical liquid injector 400 to the RIS 100.

  Then, the RIS 100 returns one imaging order data selected as described above to the control box 500. When receiving the imaging order data from the RIS 100, the control box 500 returns a part of the imaging order data to the drug solution injector 400 as at least a part of the injection condition data.

  More specifically, as described above, the imaging order data includes the imaging work ID, the identification information of the CT scanner 200, the date and time of imaging start and end, the identification information and name and weight of the subject, the body classification or imaging region, and the contrast The product name and product number of the agent, the type and size of the injection needle, etc.

  Therefore, the control box 500 determines the imaging work ID, the identification information and name and weight of the subject, the body classification or imaging part, the product name and product number of the contrast agent, the type and size of the injection needle, etc. from the acquired imaging order data. This is extracted, and this is sent back to the chemical injection device 400 as condition setting data.

  In the chemical injection device 400, the condition setting data acquired from the control box 500 in response to the acquisition request (step S8) is displayed and output on the touch panel 403 as shown in FIGS. 11 and 12 (step S9).

  At this time, the name and sex of the subject not used as the injection condition data are also displayed and output as the condition setting data, so that the operator confirms the consistency between the condition setting data and the actual subject.

  In addition to the condition setting data displayed and output as described above, the touch panel 403 also displays and outputs an operation icon for setting instructions for using or not using the condition setting data as injection condition data.

  Therefore, when the condition setting data confirmed by the operator is used as the injection condition data, an operation operation of “use” is input. Then, in the chemical solution injection device 400 that detects this (step S10), the condition setting data is set as the injection condition data (step S11).

  At this time, as shown in FIG. 11, when the imaging part is registered in the condition setting data, but the body weight or the product name of the contrast agent is not registered, only the imaging part is selected as shown in FIG. It becomes a state.

  In this case, for example, default values are automatically set for the body weight and the like, and the setting of the injection condition data is completed by inputting the product name of the contrast medium (steps S12 to S14).

  On the other hand, as shown in FIG. 12, when the condition setting data is registered as necessary and sufficient, the setting of the injection condition data is completed with the condition setting data as shown in FIG. The injection condition data set by the condition setting data as described above (steps S11 to S14) can also be corrected by the operator's input operation (steps S12 and S13).

  Even if the condition setting data is acquired from the imaging order data and the setting of the injection condition data is completed (steps S8 to S14), the chemical injection device 400 according to the present embodiment starts the chemical injection in this state. Cannot be ready.

  Therefore, when the setting of the injection condition data is completed as described above (step S14), the operator performs a final confirmation such as whether or not bubbles are mixed in the extension tube, and when this final confirmation is completed, the injection execution head is completed. The final confirmation switch 414 of 410 is input.

  Then, the chemical injection device 400 that has detected this (step S15) releases the operation lock of the chemical injection assuming that the final confirmation has been executed. However, in the chemical injection device 400 according to the present embodiment, even when the final confirmation is executed in this way and the operation lock is released, the chemical injection cannot be executed by itself.

  That is, when the final confirmation switch 414 is input as described above (step S15), the chemical injection device 400 causes the control box 500 to acquire the imaging order data from the RIS 100 again as in the first time, and a part thereof Is acquired again from the control box 500 as condition setting data (step S16).

  Then, the condition setting data set as the injection condition data is compared with the condition setting data acquired again (step S17). If the condition setting data do not match (step S17-N), for example, together with an error guidance of a confirmation warning such as “imaging order has been changed, please confirm” (step S18), the first and confirmation The acquisition date and time, a list of matched and unmatched items, non-matching data contents, and the like are displayed and output on the touch panel 403 (not shown).

  In this case, for example, when confirmation completion is input to the touch panel 403, the initial state is restored (step S3). For this reason, the injection operation is not started in a state where the imaging order data is changed.

  On the other hand, when it is confirmed that the condition setting data set as the injection condition data matches the condition setting data acquired again (step S17-Y), the touch panel 403 can input the start of injection.

  Therefore, when this injection start is input (step S19), the syringe drive mechanisms 411 and 412 are controlled in response to the set injection condition data (step S20). Saline is infused appropriately.

  At this time, the elapsed time is measured in real time and the actual injection speed is also detected, so that the operations of the syringe drive mechanisms 411 and 412 are feedback-controlled so that the injection speed matches the injection condition data.

  Further, a time-lapse graph including the actual injection speed is generated in real time and displayed on the touch panel 403 together with the injection condition data, for example. When the injection operation is completed, injection history data including a time-dependent graph of the actual injection speed is generated.

  The injection history data generated in this way includes, for example, an injection operation ID that is unique identification information for each injection operation, actual injection start and end dates and times, identification information of the chemical injection device 400, injection condition data, and injection thereof Information on whether all of the condition data has been manually input or partly acquired from the imaging order data, and if acquired from the imaging order data, from the text data such as the acquisition date and time of the first and confirmation, and the image data of the time-lapse graph Become.

  In addition, when the injection operation is completed, the chemical injection device 400 generates completion notification data that is assigned at least an injection operation ID and notifies the completion. Therefore, the chemical injection device 400 that has completed the injection operation transmits completion notification data and imaging order data to the control box 500.

  Then, the control box 500 transfers the completion notification data received from the chemical solution injector 400 to the RIS 100. The RIS 100 stores the received completion notification data in a state associated with the imaging order data by the injection work ID.

  In addition, the control box 500 transfers the injection history data received from the chemical solution injector 400 to the PACS 300. The PACS 300 stores the received injection history data in a state managed by the imaging work ID.

  In a normal operation, the imaging operation by the CT scanner 200 is started before and after the injection operation by the chemical injection device 400 is completed as described above. In this case, the operator inputs an operation to start imaging to the imaging control unit 210 of the CT scanner 200.

  Then, the imaging control unit 210 of the CT scanner 200 transmits an imaging order data acquisition request to the RIS 100. Then, the RIS 100 returns one imaging order data selected as described above to the CT scanner 200.

  Therefore, in the CT scanner 200, the fluoroscopic imaging unit 201 is controlled in accordance with the imaging order data received by the imaging control unit 210, whereby the imaging operation of the fluoroscopic image data is executed.

  When the fluoroscopic image data is captured from the subject by the fluoroscopic imaging unit 201, the imaging control unit 210 adds imaging order data to the fluoroscopic image data. Next, in the imaging control unit 210, the fluoroscopic image data to which the imaging order data is added is transmitted to the PACS 300.

  The PACS 300 stores the received fluoroscopic image data in a state managed by the imaging work ID of the imaging order data. When the operator browses the fluoroscopic image data, for example, the fluoroscopic image data is read from the PACS 300 by a manual operation of the image browsing device 600.

  In that case, for example, when the imaging work ID is input as a search key, the fluoroscopic image data of the imaging work ID is read from the PACS 300 and displayed on the display unit 602 of the image browsing apparatus 600.

  At this time, since the injection history data is also read from the PACS 300 by the imaging work ID, it is displayed on the display unit 602 of the image browsing apparatus 600 as necessary. According to the injection history data displayed in this way, whether all of the injection condition data of the injection work has been manually input or partially acquired from the imaging order data, or if acquired from the imaging order data, the first and confirmation The date and time are also confirmed.

  In the fluoroscopic imaging system 1000 according to the present embodiment, an acquisition request input to the chemical injection device 400 is transmitted to the control box 500 as described above. Then, in response to the acquisition request, the control box 500 acquires imaging order data from the RIS 100 and the CT scanner 200.

  A part of the imaging order data is transferred from the control box 500 to the chemical solution injector 400 as condition setting data. In this chemical injection device 400, a part of the condition setting data is set as a part of the injection condition data.

  For this reason, it is possible to reduce the work load for the operator to input the injection condition data, and to prevent erroneous input of the injection condition data. Nevertheless, the imaging order data is already existing and essential for the CT scanner 200. For this reason, at least a part of the injection condition data can be automatically set without requiring creation of new data.

  Moreover, the condition setting data is obtained again from the RIS 100 immediately before the injection, and the chemical solution injection based on the injection condition data is not executed unless the condition setting data matches the initial condition setting data. For this reason, it is possible to easily and reliably prevent the injection operation from being executed with the inappropriate injection condition data.

  For example, when the imaging schedule is suddenly changed and the imaging order data is corrected or deleted, the injection operation is not started corresponding to the first imaging order data.

  In addition, since the chemical solution injection device 400 notifies the operator that the imaging order data does not match, the operator can surely recognize and confirm the change of the imaging order data.

  In a general injection operation using the chemical injection device 400, the injection condition data is set by the injection control unit 401 separated from the injection execution head 410 as described above. The liquid syringe 430 and the condition of the subject are finally confirmed at the position.

  And in the chemical | medical solution injection device 400 of this Embodiment, as mentioned above, the final confirmation switch 414 for acquiring imaging order data again immediately before injection | pouring and confirming a match is arrange | positioned at the injection | pouring execution head 410. FIG.

  For this reason, it is possible to perform an input operation for acquiring the imaging order data again and confirming the coincidence at the final confirmation at the position of the injection execution head 410 that has been conventionally required. Particularly, in this chemical solution injection device 400, the operation lock of the chemical solution injection is not released unless the final confirmation is executed and the final confirmation switch 414 is input.

  For this reason, both the unlocking of the injection operation and the reconfirmation of the imaging order data by the input of the completion of the final confirmation can be executed only by inputting one final confirmation switch 414.

  Furthermore, in the chemical injection device 400 of the present embodiment, when the injection condition data is set by acquiring the imaging order data, the injection operation cannot be started unless the imaging order data is acquired and confirmed again.

  However, when all of the injection condition data is manually input, the injection operation can be started when the setting of the injection condition data is completed. For this reason, it is possible to appropriately control the prohibition and banning of the injection operation under simple conditions.

  Moreover, in the chemical injection device 400 of the present embodiment, when a part of the imaging order data is acquired as the condition setting data as described above, the condition setting data is displayed and output to the operator by the chemical injection device 400. . For this reason, the operator can confirm whether the condition setting data is appropriate.

  In particular, the names and sexes of subjects who are not used as injection condition data are also displayed and output as condition setting data. For this reason, the operator can easily and reliably confirm the matching between the condition setting data and the actual subject.

  In addition to the condition setting data displayed and output as described above, an operation icon for setting an instruction to use or not use this as injection condition data is also displayed and output. For this reason, the operator can easily input whether to use the condition setting data after confirming the condition setting data.

  Moreover, in the fluoroscopic imaging system 1000 of the present embodiment, the injection history data is also stored in association with the fluoroscopic image data stored as described above. For this reason, for example, injection history data can also be confirmed when viewing fluoroscopic image data. Therefore, an operator viewing the fluoroscopic image data can check how the chemical solution is injected into the subject when the fluoroscopic image data is captured.

  In particular, in the injection history data, all of the injection condition data is manually input or partly acquired from the imaging order data, or if it is acquired from the imaging order data, the initial date / time and the confirmation date / time are also recorded. .

  For this reason, it is possible to confirm from the injection history data how injection condition data is set, when the imaging order data is acquired and confirmed. Therefore, even when the imaging order data is corrected and the injection operation is executed, the details can be confirmed.

  In addition, as described above, the fluoroscopic image data and the injection history data are related by the imaging work ID, and the imaging work ID is acquired by the liquid injector 400 as imaging order data when the injection condition data is automatically set. The

  That is, the imaging order data acquired from the RIS 100 via the control box 500 to the chemical solution injector 400 can be used for both automatic setting of injection condition data and generation of injection history data.

  In addition, even if there is a doubt about the contrast agent injection operation, the injection history data can be confirmed together with the fluoroscopic image data, so that the injection history data can be used as evidence.

  In particular, the various apparatuses 100 to 600 of the fluoroscopic imaging system 1000 of the present embodiment mutually communicate various data according to DICOM rules. Since DICOM communication data is difficult to falsify, the evidence history of injection history data is high.

  Furthermore, even when fluoroscopic image data is imaged again from the same subject, the previous injection history data can be referred to. For this reason, accurate injection condition data can be easily input to the chemical solution injection device 400.

  In particular, even when fluoroscopic image data is re-captured from a subject whose weight has changed due to progression of a medical condition, the chemical injection device 400 can be accurately identified by referring to the previous fluoroscopic image data and injection history data. Simple injection condition data can be input easily.

  In addition, in the present embodiment, a temporal graph is included in the injection history data. Therefore, even complicated injection condition data that varies the injection speed can be easily input to the chemical solution injection device 400.

  Further, in the fluoroscopic imaging system 1000 of the present embodiment, injection history data including text data such as injection condition data is stored in the PACS 300. For this reason, for example, various statistical data related to chemical injection can be generated from a large number of accumulated injection history data.

  In particular, since the injection history data is stored together with the imaging order data, various statistical data related to the chemical solution injection can be generated together with the imaging conditions included in the imaging order data.

  In addition, the completion notification data of the injection operation is stored in the RIS 100 from the chemical injection device 400 via the control box 500. In the RIS 100, since the completion notification data is managed in association with the imaging order data, for example, the start time and end time of the chemical solution injection can be notified from the RIS 100 to the CT scanner 200 together with the imaging order data.

  In this case, since the operator who operates the CT scanner 200 can refer to the start time and end time of the chemical injection, the start time of image capturing can be adjusted according to the time.

  In addition, this invention is not limited to the said form, A various deformation | transformation is accept | permitted in the range which does not deviate from the summary. For example, in the above embodiment, when the imaging order data is acquired and the injection condition data is set, when the final confirmation is input, the imaging order data is acquired again and the match is confirmed. Exemplified that

  However, when the imaging order data is acquired and the injection condition data is set, when the injection start is input, the imaging order data is acquired again and the match is confirmed. If the match is not confirmed, the chemical injection starts. Instead, when the match is confirmed, the chemical injection may be started.

  In the above embodiment, all of the imaging order data managed by the RIS 100 is acquired in the control box 500, and a part of the imaging order data is acquired as condition setting data from the control box 500 to the drug solution injector 400. An example is shown in which a part of the setting data is set by the chemical liquid injector 400 as a part of the injection condition data.

  However, all of the imaging order data may be acquired by the chemical injection device 400 as condition setting data. Further, all of the condition setting data may be set as part of the injection condition data, or part of the condition setting data may be set as all of the injection condition data.

  Furthermore, in the said form, it illustrated that the control box 500 transfers the imaging order data acquired from RIS100 to the chemical | medical solution injection apparatus 400 as a part of injection condition data.

  However, the control box 500 may transfer all of the imaging order data to the chemical injection device 400, and select a part of the imaging order data received by the chemical injection device 400 as injection condition data.

  Moreover, in the said form, RIS100 was a push type | mold and it illustrated that control box 500 acquires appropriate imaging order data by timing. However, the RIS 100 may be a pull type.

  In that case, the CT scanner 200 transmits an imaging order data acquisition request to the RIS 100 together with at least one order search key. Then, the RIS 100 selects and returns one of the plurality of imaging order data corresponding to the acquisition request and the order search key received from the CT scanner 200.

  When receiving the acquisition request, the control box 500 transmits an acquisition request for imaging order data to the RIS 100. Then, the RIS 100 returns one imaging order data selected corresponding to the acquisition request received from the control box 500.

  Alternatively, the RIS 100 returns a plurality of imaging order data in response to the acquisition request received from the CT scanner 200. In this case, the CT scanner 200 receives an operation for selecting one of the returned plurality of imaging order data, and notifies the RIS 100 of the selected imaging order data.

  Alternatively, the RIS 100 searches for a part from a plurality of imaging order data in response to the acquisition request received from the CT scanner 200 and the order search key, and sends back a part. The CT scanner 200 accepts an operation for selecting one of the returned imaging order data, and notifies the RIS 100 of the selected imaging order data.

  Therefore, when the control box 500 transfers the acquisition request for the imaging order data to the RIS 100, the RIS 100 returns one imaging order data notified from the CT scanner 200 in response to the acquisition request received from the control box 500. .

  By doing as described above, even when the RIS 100 is a pull type, the control box 500 can acquire appropriate imaging order data, and can give imaging work ID and the like to the injection history data.

  Moreover, in the said form, it illustrated that the control box 500 acquires the imaging order data provided from RIS100 unconditionally. However, the control box 500 may transmit an imaging order data acquisition request to the RIS 100 together with at least one order search key.

  In this case, the RIS 100 searches for a part from a plurality of imaging order data corresponding to the order search key received from the control box 500, and the CT scanner 200 notifies the searched part of the imaging order data. Reply if there is one. As described above, the control box 500 can acquire appropriate imaging order data more reliably.

  In the above case, for example, the chemical injection device 400 transmits at least part of the input injection condition data as an order search key to the control box 500 together with the acquisition request, and the control box 500 receives the received acquisition. The request and the order search key may be transferred to the RIS 100.

  Furthermore, in the said form, it illustrated that the control box 500 acquires imaging order data from RIS100. However, the RIS 100 and the CT scanner 200 may be connected via the control box 500, and the control box 500 may acquire imaging order data transmitted from the RIS 100 to the CT scanner 200.

  Further, the control box 500 may be connected to the CT scanner 200 without being connected to the RIS 100, and the control box 500 may acquire imaging order data from the CT scanner 200.

  In this case, for example, the control box 500 transfers an acquisition request received from the chemical solution injector 400 to the CT scanner 200, and the CT scanner 200 returns imaging order data in response to the acquisition request received from the control box 500. That's fine.

  Alternatively, the CT scanner 200 may accept an operation for selecting one of a plurality of imaging order data returned from the pull-type RIS 100 and transfer the selected imaging order data to the control box 500.

  Further, the control box 500 may be connected to the RIS 100 and the CT scanner 200, the first imaging order data may be acquired from the RIS 100, and the confirmation imaging order data may be acquired from the CT scanner 200.

  Further, in the above embodiment, the injection history data generated by the chemical solution injection device 400 is stored in the PACS 300 together with the fluoroscopic image data generated by the CT scanner 200.

  However, the injection history data may be transmitted from the chemical solution injection device 400 to the RIS 100 via the control box 500, and the injection history data may be stored in the RIS 100. In this case, the RIS 100 can manage the imaging order data and the injection history data in association with the work ID.

  Even in this case, the fluoroscopic image data registered in the PACS 300 is also assigned the work ID of the imaging order data, so that the fluoroscopic image data and the injection history data can be associated with each other.

  Further, in the above embodiment, the entire imaging order data is given to the fluoroscopic image data and stored in the PACS 300. However, only the imaging work ID of the imaging order data may be assigned to the fluoroscopic image data.

  Even in this case, the fluoroscopic image data and the injection history data can be associated by the imaging work ID, and the imaging order data can be read from the RIS 100 by the imaging work ID.

  Alternatively, only the imaging work ID of the imaging order data may be assigned to the fluoroscopic image data, and all of the imaging order data may be assigned to the injection history data. The imaging order data is assigned to the fluoroscopic image data and the injection history data. May be.

  Furthermore, the injection history data may include both the time graph and the injection condition data. The entire display image on the touch panel 403 of the chemical liquid injector 400 may be included in the injection history data.

  Moreover, in the said form, it illustrated that injection | pouring log | history data consisted of text data, such as injection | pouring operation ID and a date, and image data of the time-dependent graph of injection | pouring speed | rate. However, the injection history data may consist only of the text data described above.

  In particular, in the above-described embodiment, the chemical solution injection device 400 variably changes the injection speed of the contrast agent, and the time-lapse graph is included in the injection history data. However, the chemical solution injector 400 may inject the contrast agent at a constant speed. In this case, it is less meaningful to generate and record a time graph. Therefore, it is preferable that the injection speed is included in the injection history data as text data.

  Moreover, in the said form, it illustrated only that injection | pouring condition data was set to the chemical | medical solution injection apparatus 400. FIG. However, the injection condition data may be notified from the chemical solution injection device 400 to the control box 500, and the injection condition data may be notified from the control box 500 to the RIS 100. In this case, the injection condition data can be notified from the RIS 100 to the CT scanner 200 together with the imaging order data.

  Accordingly, since the operator who operates the CT scanner 200 can refer to the injection condition data, the imaging operation can be adjusted in accordance with the injection condition data. In addition, it is not impossible to automatically adjust the imaging operation based on the injection condition data acquired by the imaging control unit 210 of the CT scanner 200.

  Moreover, in the said form, after completing injection | pouring log | history data with the chemical | medical solution injection apparatus 400, transmitting to the control box 500 was illustrated. However, the chemical injection device 400 may distribute the injection history data to the control box 500 and transmit it, and the control box 500 may complete the injection history data.

  More specifically, the chemical solution injection device 400 transmits injection condition data, start date and time, etc. to the control box 500 at the start of injection, transmits the injection speed and the like sequentially during the injection process, and transmits end date, etc. at the end of injection. . In this case, the injection history data can be completed and output from various data accumulated by the control box 500 from the start of injection to the end of injection.

  Moreover, in the said form, the various apparatuses 100-600 illustrated that the evidence ability, such as injection | pouring log | history data, is high by mutually communicating various data in the DICOM format which is hard to tamper. However, the chemical injection device 400 may generate injection history data in a data format that is difficult to falsify, such as PDF (Portable Document Format).

  Similarly, the injection history data received in the JPEG (Joint Photographic Coding Experts Group) format from the chemical solution injector 400 may be converted into the PDF format by the control box 500. Furthermore, the chemical injection device 400 and the control box 500 may be connected to a so-called Internet, and an electronic signature may be acquired and added to the injection history data.

  Further, in the above embodiment, injection condition data including imaging order data acquired from the RIS 100 via the control box 500 by the chemical injection device 400 is displayed on the touch panel 403 of the injection control unit 401 separate from the injection execution head 410. Exemplified that

  However, a small display panel (not shown) may be juxtaposed with the injection execution head 410 as a data display unit, and injection condition data including imaging order data may be displayed there. In this case, the injection condition data can be confirmed at the position of the injection execution head 410 that is arranged in the vicinity of the subject and to which the drug solution syringe 430 is attached.

  Moreover, in the said form, all injection | pouring condition data which the chemical | medical solution injection apparatus 400 requires were illustrated extracting from the imaging order data acquired from RIS100. However, only part of the injection condition data required by the chemical injection device 400 may be acquired from the imaging order data, and the other part may be input to the chemical injection device 400.

  Furthermore, injection condition data such as identification information of a subject is input to the drug solution injection device 400, and the drug injection device 400 compares the injection condition data with the injection condition data acquired from the imaging order data. If the condition data does not match, a warning may be notified.

  In this case, it is possible to prevent the injection condition data from being automatically set with incorrect imaging order data. Further, if such a warning is displayed on the display panel of the injection execution head 410 described above, the worker can be promptly and surely recognized.

  An RFID chip in which at least a part of the condition setting data is recorded is mounted on the chemical solution syringe 430, and an RFID reader that reads at least a part of the condition setting data from the RFID chip is mounted on the chemical solution injection device 400. Therefore, the chemical liquid injector 400 may collate the injection condition data of the RFID chip of the chemical syringe 430 with the injection condition data acquired from the imaging order data (not shown).

  In this case, it is possible to prevent the injection condition data from being automatically set with the wrong imaging order data and the chemical injection with the wrong chemical syringe 430. Nevertheless, it is not necessary for the operator to input the injection condition data, and erroneous input can be prevented.

  Further, the chemical product ID is recorded on the RFID chip as described above, and at least the chemical product ID unsuitable for injection is set in the imaging order data as the unsuitable ID for each subject. The product ID input from the RFID chip and the inappropriate ID set in the condition setting data are collated, and a warning may be notified if they match (not shown).

  More specifically, the prefilled type drug solution syringe is shipped in a state where the drug solution is filled. Therefore, an RFID in which chemical liquid data is registered as data storage means is attached to a prefilled type chemical syringe (not shown).

  The chemical liquid data includes, for example, various data such as volume, pressure resistance, cylinder inner diameter, piston stroke, identification data for each individual, and product ID, chemical classification, content component, It consists of various data such as viscosity and expiration date.

  The product ID of the chemical solution is registered due to the chemical classification, the contained component, and the chemical structure of the chemical solution, and is not related to the syringe capacity. For example, if there are products from Company A and Company B as contrast agents for the heart for CT, the type of drug solution “contrast agent for the heart for CT” is common, but is it water-soluble or oily? If the chemical classification such as ionic or nonionic, monomer type or dimer type is different, the product ID is different.

  Furthermore, even if the chemical type and chemical classification are the same, the product ID will be different if the contained components are different. For example, even if the chemical type, chemical class and contained component are common, the chemical structure of the contained component is the same. If they are different, the product ID is different.

  On the other hand, if the same chemical solution is filled in the prefilled type drug syringes with the capacity of "200 (ml)" and "500 (ml)", the drug solution syringe is separate as a product depending on the volume. The product IDs are the same.

  On the other hand, in the imaging order data, in addition to the subject ID for each subject, personal data such as sex and age, various data related to diseases, etc., the above-mentioned inappropriate ID, etc. are also registered. In such a state, when the chemical syringe is appropriately loaded in the injection execution head of the chemical injection device, the chemical data is acquired from the RFID chip by the RFID reader.

  When the chemical solution injection device acquires the injection condition data from the imaging order data, the inappropriate ID set in the injection condition data and the product ID set in the chemical solution data are collated.

  When the product ID and the inadequate ID match, a warning message such as “This drug cannot be injected into this subject” is displayed on the touch panel and the operation of the syringe drive mechanism is disabled.

  For this reason, for example, when a chemical solution injected into a subject is appropriate for a CT contrast agent or the like, but is unsuitable for the subject's personal reasons such as side effects, the chemical solution injection device automatically handles this. Can be detected and notified to the operator. Therefore, the operator can quickly recognize itself and take measures such as changing the chemical solution.

  In particular, the product ID is automatically acquired when the chemical syringe is loaded in the injection execution head, and the inappropriate ID is automatically acquired when the imaging order data is input as the injection condition data. For this reason, there is no need for a dedicated work for the acquisition and collation, and the product ID and the inappropriate ID can be collated easily and reliably.

  Similarly, it is also possible to record the chemical component contained in the RFID chip of the chemical syringe, register the inappropriate component as an inappropriate component in the imaging order data, and check the contained component against the inappropriate component. It is.

  It is also possible to record the chemical classification of chemicals in the RFID chip of the chemical syringe, register the chemical classification that is inappropriate for injection in the imaging order data as an inappropriate classification, and collate the chemical classification with the inappropriate classification. is there.

  In these cases, it is possible to manage the suitability of the injection to the subject for each component and chemical classification. For this reason, for example, it is possible to accurately predict whether or not a chemical solution is injected for the first time.

  Furthermore, the syringe drive mechanism is initially set to be inoperative until it is confirmed whether or not an inappropriate ID or the like is registered in the imaging order data, or if an inappropriate ID or the like does not match with the product ID when registered. You can also keep it. In this case, it is possible to reliably and automatically prevent an unsuitable chemical solution from being injected into the subject.

  As described above, the imaging order data is generally created from the electronic medical record for each subject, and the electronic medical record includes the product ID, content component, chemical classification, etc. of drugs that have side effects. It can be registered as a classification. For this reason, the imaging order data in which the unsuitable ID and the like are registered as described above can be easily created.

  Moreover, when the chemical | medical solution injection device 400 alert | reports a warning as mentioned above, you may control the syringe drive mechanisms 411 and 412 to be inoperable until the warning is cancelled | released. In this case, it is possible to prevent the medicinal solution that is a warning target from being injected into the subject.

  Furthermore, in the said form, the chemical | medical solution injection apparatus 400 illustrated inject | pouring only a contrast agent into a test subject with the one chemical | medical solution syringe 430. However, the chemical solution injector may inject a contrast medium, physiological saline, or the like as a chemical solution into the subject using a plurality of chemical syringes (not shown). In such a case, for example, injection condition data for sequentially injecting a contrast medium and physiological saline as a drug solution to a subject can be registered in the imaging order data.

  Moreover, in the said form, CT scanner 200 was used as a fluoroscopic imaging device, and it illustrated that the chemical | medical solution injection device 400 inject | poured the contrast agent for CT as a chemical | medical solution. However, the fluoroscopic imaging apparatus may be composed of an MRI, PET apparatus, ultrasonic diagnostic apparatus, or the like, and the chemical solution injection apparatus may inject a contrast agent for the apparatus.

  Furthermore, in the said form, it illustrated that CT scanner 200 and the chemical | medical solution injection device 400 operate | move stand-alone individually. However, the CT scanner 200 and the chemical solution injector 400 may link various operations through data communication.

  Further, in the above embodiment, for simplicity of explanation, it is illustrated that each part of the fluoroscopic imaging system 1000 is one. However, in a large-scale hospital or the like, each of a plurality of fluoroscopic imaging systems has one RIS 100, a CT scanner 200, a chemical liquid injector 400, and a control box 500, and the plurality of fluoroscopic imaging systems include a PACS 300 and an image browsing device. 600 may be shared (not shown). However, even in such a case, a plurality of hardware such as the RIS 100, the PACS 300, and the image browsing apparatus 600 may be connected in parallel (not shown).

  Further, in the above embodiment, the fluoroscopic image data and the injection history data are stored in one PACS 300. However, the hardware for storing the fluoroscopic image data and the hardware for storing the injection history data may be formed separately and connected via a communication network.

  Moreover, in the said form, it illustrated that RIS100, CT scanner 200, PACS300, the chemical | medical solution injection apparatus 400, the control box 500, and the image browsing apparatus 600 were formed separately, and were connected by the communication networks 701-706. .

  However, the various devices 100 to 600 as described above may be integrally formed in various combinations. For example, the injection control unit 401 and the control box 500 of the chemical liquid injector 400 are integrally formed, the RIS 100 and the PACS 300 are integrally formed thereon, and the PACS 300 and the image browsing device 600 are integrally formed. It is also possible.

  It is also possible that the RIS 100 and the PACS 300 are integrally formed in the control box 500, the control box 500, the PACS 300, and the image browsing apparatus 600 are integrally formed.

  Furthermore, the imaging control unit 210, the RIS 100, and the control box 500 of the CT scanner 200 are integrally formed, and the imaging control unit 210, the PACS 300, and the control box 500 of the CT scanner 200 are integrally formed. It is also possible for the image browsing apparatus 600 to be formed integrally therewith.

  In addition, the image browsing apparatus 600 and the PACS 300 can be integrally formed, and the control box 500 and the imaging control unit 210 of the CT scanner 200 can be integrally formed.

  Furthermore, in the said form, it illustrated that each part of the various apparatuses 100-600 was logically implement | achieved as various functions, when a computer apparatus operate | moves corresponding to a computer program.

  However, each of the units can be formed as unique hardware, and a part can be formed as software and a part can be formed as hardware.

  Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the present invention.
