FIG. 3 is a flow diagram of a medical imaging method in one embodiment. As shown in fig. 3, a method of medical imaging, the method may comprise the steps of:

step S1, make the imaging positioning Interface (GLI) correspond to the scanning progress in real time.

Illustratively, the information displayed by the imaging layer positioning frame corresponds to the scanning progress of the current scanning operation in real time so as to establish the real-time corresponding relation between the imaging layer positioning frame and the scanning progress.

And step S2, displaying the scanning progress in real time by the positioning frame of the imaging slice layer during the scanning and imaging operation of the scanning object.

Illustratively, in the process of performing scanning imaging operation on a scanning object, the imaging slice positioning frame displays parameter information related to the current scanning progress in real time, so that an operator can visually check the progress information of the current scanning operation, and further, the scanning operation is convenient to control.

Specifically, during the multi-bed medical scanning imaging process of a patient by using a scanning imaging system such as PET, PET-MR, PET-CT or MR, the scanning progress related parameter information of the current scanning operation is acquired in real time, and after data processing and conversion are performed on the related parameter information, the related parameter information is dynamically displayed in real time in the imaging layer positioning frame in a form such as a progress bar, so that an operator (such as a doctor) can control the current scanning operation performed on the patient in real time.

In an alternative embodiment, the imaging slice positioning frame can display the scanning status information of the bed and the scanning progress information of the current scanning bed in real time, so as to present the scanning progress of the scanning operation in real time.

In another alternative embodiment, when the imaging slice positioning frame displays the scanning state information of the bed, only the currently scanned bed may be displayed in the first display mode, and no other bed is displayed, or other beds are displayed in a gray scale display mode, so as to highlight the information related to the currently scanned bed, so that the operator can conveniently control the currently scanned bed.

In addition, in order to improve the integral grasp of the operator on the whole scanning process, the bed which is scanned is displayed in a second display mode and the bed to be scanned is displayed in a third display mode while the bed which is scanned currently is displayed in the imaging slice layer positioning frame in a first display mode; the first display mode, the second display mode and the third display mode can be different from each other to increase the distinction degree between the first display mode and the second display mode. Wherein, at least the first display mode needs to be different from the other two display modes to highlight the currently scanned bed.

Specifically, when a PET scanning imaging system is used to perform multi-bed scanning imaging on a patient, information such as a currently scanned bed and a scanning progress can be displayed in a protocol examination list area, and a currently scanned bed and a scanning progress of the scanned bed can be synchronously displayed in an imaging slice positioning frame, for example, the scanning progress of a PET protocol can be displayed in real time in a progress bar form on the imaging slice positioning frame, and the scanned bed is covered, while a bed to be scanned is exposed (i.e., not covered). Meanwhile, in order to improve the distinction degree between beds in different scanning bodies, the beds which have finished scanning, the beds in scanning and the beds to be scanned can be respectively displayed in different colors and other modes. For example, the scanned bed can be displayed in a green manner, or the scanned bed can be covered by using the background canvas, so that the scanned bed can be marked obviously; the bed in scanning can be displayed in a yellow mode, and meanwhile, the bed can be displayed in a highlight and flashing mode, so that the distinguishing degree of the bed in scanning and other beds is improved; the bed to be scanned can be displayed in a red mode, and meanwhile, special marks can be added to improve the distinguishing degree of the bed to be scanned. In an alternative embodiment, during the scanning and imaging operation of the scanning object, when the protocol adjustment requirement occurs, the scanning parameters in the currently used scanning protocol can be modified or a new scanning protocol is added according to the scanning information. For example, when the scanning cannot be continued by using the current protocol or the acquired image quality parameter of the currently acquired image does not meet the preset requirement, the scanning parameters in the currently used scanning protocol can be adjusted and modified according to the scanning information such as the lesion position information and/or the anatomical structure position information, so that the scanning object can be subjected to normal scanning imaging operation by using the modified scanning protocol.

The following describes in detail the image quality parameter of the acquired current captured image as an example, which does not meet the preset requirement:

FIG. 4 is a flow diagram for adjusting a scan protocol based on an image quality parameter in one embodiment. As shown in fig. 4, a method of medical imaging may comprise the steps of:

step S01, in the process of performing the scanning imaging operation on the scanning object according to the called standard scanning protocol, acquiring the image quality parameter of the currently acquired image in the scanning imaging operation in real time.

For example, the medical imaging method in this embodiment may be based on a scanning imaging system such as PET, PET-MR, PET-CT, or MR, when performing multi-bed medical scanning imaging on a patient, a scanning protocol that is currently standard in the industry may be selected according to a patient condition of the patient to perform a certain bed scanning imaging operation on the patient; and in the process of carrying out scanning imaging operation on the bed, acquiring the image quality parameters of the image acquired by the current scanning imaging operation in real time.

In an alternative embodiment, the image quality parameter may include values such as a graphic definition, an image tone range value, an image color, and/or an image brightness.

And step S02, judging whether the acquired image quality parameters meet the preset requirements.

For example, the preset requirement of the image quality parameter in the embodiment may be that some or all values in the image quality parameter are within respective set value ranges, so as to implement an automatic determination operation; of course, the acquired image quality parameters can also be displayed in an image display mode, so that an operator can conveniently judge and input a judgment instruction, and further whether the current scanning imaging operation is effective or not is judged.

And step S03, under the condition that the image quality parameter can not meet the preset requirement, adjusting the standard protocol in use to form a real-time scanning protocol, and continuing to perform scanning imaging operation on the scanning object according to the real-time scanning protocol.

Illustratively, according to the result determined in step S02, if the image acquired by the current scanning imaging operation cannot meet the requirement, for example, if the current acquired image has defects such as insufficient definition, insignificant image tone range, unclear image color and/or insufficient image brightness, etc., it indicates that the currently used scanning protocol may not conform to the actual situation, at this time, the standard scanning protocol in use may be adjusted in real time to form a real-time scanning protocol, and then the scanning imaging operation of the bed is performed according to the real-time scanning protocol; in case the image quality problem appears in the in-process of scanning a certain bed promptly can adjust the scanning agreement that adopts in real time to adopt the scanning agreement after the adjustment to scan the imaging operation in the remaining scanning step of this bed, just so can effectually avoid scanning the patient again because of scanning agreement problem, and then promote the ageing of scanning, greatly reduced patient receives the time of radiation.

FIG. 5 is a flow chart of a method for medical imaging based on image quality parameter adjustment scan protocol in another embodiment. As shown in fig. 5, in another embodiment, a medical imaging method may comprise the steps of:

in step S10, a scan imaging operation is performed on the scan object according to the invoked standard scan protocol.

Illustratively, on the basis of a scanning imaging system such as PET, PET-MR, PET-CT or MR, when a patient is scanned and imaged medically, a standard scanning protocol may be selected to scan and image the patient at a corresponding bed position according to parameters such as patient data of the patient. The standard scanning protocol is generally a standard protocol prepared for specific types of diseases and patients based on medical experience or data analysis in the industry.

And step S11, acquiring the image quality parameter of the image currently acquired by the scanning imaging operation.

Illustratively, during the above-described one-bed scanning imaging operation on the patient using the selected standard scanning protocol, the image quality parameters of the images acquired by the current scanning imaging operation are acquired in real time.

And step S12, judging whether the acquired image quality parameters meet the preset requirements. If yes, go to step S16; otherwise, the process continues to step S13.

For example, the image quality parameter may include values such as a graphic definition, an image tone range value, an image color, and/or a brightness of an image; that is, whether the above-mentioned partial or all numerical values are within the corresponding preset range can be determined, and whether the preset requirements are met can be determined based on whether the images acquired in the scanning imaging operation process affect the subsequent treatment operation.

And step S13, adjusting the called scanning standard protocol to form a real-time scanning protocol.

Illustratively, the adjustment may include operations such as modifying, deleting and/or adding protocol parameters in the invoked standard scanning protocol to form a real-time scanning protocol, and continuing the scanning imaging operation on the scanning object according to the real-time scanning protocol. For example, if the acquired image is unclear due to the fact that the scanning area of the patient is too thick, the acquired image can be adjusted by increasing and modifying the power parameter of the radioactive source in the scanning protocol, and accordingly, the original protocol parameter can be deleted and/or a new protocol parameter can be added according to the current actual situation, and the adjusted scanning protocol is used as a real-time scanning protocol to perform subsequent scanning imaging operation.

Step S14, it is confirmed whether the real-time scanning protocol meets the modification requirement. If the modification requirement is satisfied, continuing to step S15; otherwise, the process proceeds to step S16.

For example, after the adjustment of the standard scanning protocol is completed, in order to avoid that the real-time scanning protocol formed after the adjustment does not conform to the relevant medical instrument regulations or does not match with the actual conditions due to misoperation, the real-time scanning protocol formed after the adjustment can be confirmed after the standard scanning protocol is adjusted; the confirmation operation can be confirmed by other operators more experienced than the adjustment operator, or can be checked directly by the operator, or can be integrated and set the range value of each scanning protocol parameter based on the current big data analysis or some medical experience, and the automatic confirmation operation can be realized by judging whether the adjusted scanning protocol parameters are in the respective corresponding ranges.

In one embodiment, in order to improve the accuracy of the adjustment operation, an adjustment range of each scan protocol parameter may be set during the adjustment operation, and the adjustment range may be selected only within the adjustment range; for example, an adjustment option for each scan protocol parameter is set, and the operator performs an adjustment operation by selecting the corresponding adjustment option. Furthermore, when the operator completes the adjustment of the corresponding scanning protocol parameters, different scanning protocol parameter combination options are defined, so as to avoid that the finally formed real-time scanning protocol cannot be realized due to the mismatching of different scanning protocol parameters.

And step S15, continuing to perform scanning imaging operation on the scanning object according to the real-time scanning protocol.

Illustratively, when the acquired image is found to be unqualified in the process of performing scanning imaging operation on a certain bed, the real-time scanning protocol formed after adjustment is used for replacing the scanning protocol being adopted to perform subsequent scanning imaging operation on the bed, so as to acquire the image meeting the requirement by using the rest scanning imaging operation of the bed as far as possible, thereby avoiding the failure of the whole bed scanning operation caused by unqualified image acquired by the current scanning imaging operation, further avoiding the increase of the time length of the patient subjected to scanning ray radiation, and simultaneously saving the scanning imaging resources and power consumption.

In step S16, the scanning imaging operation of the scanning object is continued according to the standard scanning protocol.

Illustratively, this step is to illustrate that the currently adopted standard scanning protocol conforms to the actual scanning situation when the currently acquired image is judged to meet the requirement, so that the current scanning operation can be continued by using the current standard scanning protocol.

In another alternative embodiment, referring to fig. 5, after steps S15 and S16, steps S11, S12 and their corresponding steps may be continued to determine the images acquired by the scanning imaging operation in real time, so as to ensure that the scanning imaging operation of each bed is effective.

In another embodiment, while the above steps of the medical imaging method are performed, that is, during the scanning and imaging operation of the scanned object, data and images, such as patient parameters, treatment parameters, physiological parameters, and current scanning operation state information, may be simultaneously displayed in real time on an interface, such as an imaging slice positioning frame, so as to facilitate monitoring of the scanning and imaging operation by an operator, facilitate determination of the quality of the currently acquired images, and correspondingly adjust the scanning protocol in real time according to the displayed parameters. The current scanning operation state parameters may include information such as scanning states of all beds and scanning progress of the current scanning bed, the patient parameters may include information such as a lesion position, the treatment parameters may include information such as an anatomical position, and the physiological parameters may include information such as a body thickness at the anatomical position.

In addition, according to different scanning states of the bed, the bed can be displayed in a distinguishing way in an interface such as an imaging slice positioning frame. For example, the scanned bed is displayed in gray, or the scanned bed can be covered by using the background canvas, so as to obviously mark the scanned bed; the bed in scanning is displayed in a green mode, and meanwhile, the bed can be displayed in a highlight and flashing mode, so that the distinguishing degree between the bed in scanning and other beds is improved; the bed to be scanned is displayed in yellow, and the distinction between the bed to be scanned and other beds can be improved by other special marks such as identifiers.

FIG. 6 is a timing diagram of a method of medical imaging based on an image quality parameter adjustment scan protocol in one embodiment. As shown in FIG. 6, when a scanning imaging system such as PET, PET-MR, PET-CT or MR is used to perform multi-bed scanning imaging operation on a patient, the scanning frame can be started by sending a starting instruction through the operation console; then, according to the parameters of the patient, the physiology and the like of the current patient, selecting a standard scanning protocol corresponding to the standard scanning protocol from a plurality of standard scanning protocols prestored in the main cabinet; the scanning frame calls the selected standard scanning protocol and performs a certain bed scanning imaging operation on the patient according to the standard scanning protocol. During the scanning and imaging operation of the scanning frame on the patient, the scanning frame transmits the acquired image data to the main cabinet in real time, and the main cabinet performs operations such as storage, processing and image reconstruction on the received image data in real time and transmits the image data acquired by the current scanning frame or subjected to image reconstruction to the operation console in real time. The operation console judges whether the received image data is qualified or not in real time, and adjusts the scanning protocol adopted by the current scanning rack in real time when the received image data is unqualified. And the scanning machine frame continues to perform subsequent scanning imaging operation on the bed according to the adjusted scanning protocol. In order to ensure that the scanning imaging operation of each bed is effective, the image quality judgment and the scanning protocol adjustment operation can be circularly performed in real time.

In another embodiment, the image acquired by the scanning frame using the real-time adjustment scanning protocol meets the standard, and the real-time adjustment scanning protocol and the corresponding parameters related to the current patient and the scanning frame can be stored in the main cabinet as the standard scanning protocol, so as to be convenient for the selection and invocation in the subsequent scanning imaging.

FIG. 7 is a schematic view of a medical imaging apparatus in one embodiment. As shown in fig. 7, a medical imaging apparatus, a corresponding module 11 and a display module 12; the corresponding module 11 can be used for corresponding the imaging slice layer positioning frame to the scanning progress in real time; the display module 12 can be used to display the scanning progress in real time on the positioning frame of the imaging slice during the scanning and imaging operation of the scanned object.

Illustratively, the corresponding module 11 corresponds the information displayed by the imaging layer positioning frame to the scanning progress of the current scanning operation in real time, so as to establish a real-time corresponding relationship between the imaging layer positioning frame and the scanning progress. The display module 12 displays the parameter information related to the current scanning progress in the imaging slice positioning frame in real time during the scanning and imaging operation of the scanning object, so that an operator can visually check the progress information of the current scanning operation, and the scanning operation is convenient to control.

Fig. 8 is a schematic diagram of the display module of fig. 7. As shown in FIG. 8, in an alternative embodiment, the display module 12 may include a first display sub-module 121 and a second display sub-module 122; the scanning progress can comprise information such as scanning state information of the bed, scanning progress information of the current scanning bed and the like; the first display sub-module 121 may be configured to display the scanning status information of the bed in real time in the imaging slice positioning frame, and the second display sub-module 122 may be configured to display the scanning progress information of the currently scanned bed in real time in the imaging slice positioning frame.

FIG. 9 is a schematic diagram of the first display sub-module of FIG. 8. As shown in fig. 9, in another alternative embodiment, the scanning status information may include a bed currently being scanned, a bed that has completed scanning, and a bed to be scanned, and the first display sub-module 121 may include a first display sub-unit 1211, a second display sub-unit 1212, a third display sub-unit 1213, and so on; the first display subunit 1211 can be used for displaying the currently scanned bed in a first display manner, the second display subunit 1212 can be used for displaying the scanned bed in a second display manner different from the first display manner, and the third display subunit 1213 can be used for displaying the bed to be scanned in a third display manner different from the first display manner and the second display manner.

For example, when the imaging slice positioning frame displays the scanning status information of the bed, the first display subunit 1211 may be used to display the currently scanned bed in the first display manner, but not display other beds, so as to highlight the information related to the currently scanned bed, so that the operator can conveniently manipulate the currently scanned bed. In addition, in order to improve the overall understanding of the operator on the whole scanning process, the bed currently scanned may be displayed in the imaging slice positioning frame in the first display mode by using the first display subunit 1211, and the bed that has been scanned may be displayed in the second display mode by using the second display subunit 1212, and the bed to be scanned may be displayed in the third display mode by using the third display subunit 1213; because the first display mode, the second display mode and the third display mode are different from each other, the degree of distinction among beds in different scanning states can be effectively increased.

Specifically, when the PET scanning imaging system is used to perform multi-bed scanning imaging on a patient, information such as a currently scanned bed and a scanning progress can be displayed in the protocol examination list area, and the display module 12 is used to synchronously display the currently scanned bed and the scanning progress of the scanned bed in the imaging slice positioning frame, for example, the scanning progress of the PET protocol can be displayed in real time in the form of a progress bar on the imaging slice positioning frame, and the scanned bed is covered, while the bed to be scanned is exposed (i.e., uncovered). Meanwhile, in order to improve the distinction degree between beds in different scanning bodies, the beds which have finished scanning, the beds in scanning and the beds to be scanned can be respectively displayed in different colors and other modes. For example, the first display subunit 1211 may display the scanned bed in a green manner, or the scanned bed may be covered by a background canvas to obviously mark the scanned bed; the second display subunit 1212 can be used to display the scanned bed in yellow, and can also display the scanned bed in a highlight and flashing manner, so as to improve the distinction between the scanned bed and other beds; the third display subunit 1213 can be used to display the bed to be scanned in red, and some special marks can be added to improve the resolution of the bed to be scanned.

Fig. 10 is a schematic structural diagram of a medical imaging apparatus in another embodiment. As shown in fig. 10, in an alternative embodiment, the medical imaging apparatus may further include an adjusting module 13, configured to add a new scanning protocol or modify scanning parameters in a currently used scanning protocol according to the scanning information when a protocol adjustment requirement occurs during a scanning imaging operation on a scanning object. For example, when the scanning cannot be continued by using the current protocol or the acquired image quality parameter of the currently acquired image does not meet the preset requirement, the adjustment module 13 may adjust and modify the scanning parameter in the currently used scanning protocol according to the scanning information, such as the lesion position information and/or the anatomical structure position information, so as to perform a normal scanning imaging operation on the scanned object by using the modified scanning protocol.

FIG. 11 is a block diagram of a medical imaging device that adjusts a scan protocol based on image quality parameters for scan imaging in one embodiment. As shown in fig. 11, in an alternative embodiment, the medical imaging apparatus may further include an acquisition module 14, and the acquisition module 14 may be configured to acquire scan parameters in real time during a scan imaging operation on a scan object; the display module 12 can display the scan parameters acquired by the acquisition module 14 in real time, so as to facilitate the monitoring of the scanning imaging operation by the operator.

Specifically, the display module 14 can be used for displaying the scanning parameter information such as patient parameters, treatment parameters, physiological parameters, and current scanning operation status in real time during the scanning and imaging operation of the scanning object. The current scanning operation state parameters can include scanning states of all beds, scanning progress of the current scanning bed and other medical equipment related to the current patient and operation information; patient parameters may include information related to the patient's disease, such as the location of the lesion, the cause of the disease, and the condition of the disease; the treatment parameters comprise diagnosis and treatment information of diseases of the patient to be treated, such as anatomical positions, operation types, medication conditions and the like; the physiological parameters include various physiological information of the patient at present, such as body thickness information at the anatomical site, real-time blood pressure, real-time heartbeat, and the like. Corresponding display information can be added or deleted according to actual conditions in the actual scanning imaging operation process, so that the real-time observation and control of operators are facilitated.

FIG. 12 is a block diagram of a medical imaging device for adjusting a scan protocol based on image quality parameters for scan imaging in another embodiment. As shown in fig. 12, a medical imaging apparatus may further include an acquisition module 15 and a determination module 16; the obtaining module 15 may be configured to obtain an image quality parameter of an image acquired by the current medical imaging apparatus during a scanning and imaging operation performed on a scanned object according to the called standard scanning protocol, that is, as shown in fig. 11 to 12, the acquiring module 14 and the obtaining module 15 may work simultaneously; the judging module 16 may be configured to judge whether the image quality parameter meets a preset requirement; the adjusting module 13 may be configured to adjust the called standard scanning protocol when the determining module 16 determines that the image quality parameter does not meet the preset requirement, and may continue to perform the scanning and imaging operation on the scanning object by using the adjusted scanning protocol; the display module 12 is used for acquiring the image in real time during the scanning and imaging operation.

Illustratively, in the process of scanning and imaging the scanning object by the medical imaging apparatus using the standard scanning protocol, the obtaining module 15 obtains an image quality parameter of an image acquired by the current medical imaging apparatus, the determining module 16 determines whether the obtained image quality parameter meets a preset requirement, that is, determines whether the acquired image is qualified, and once it is determined that the image quality parameter does not meet the preset requirement, the adjusting module 13 is used to adjust the scanning protocol used by the current medical imaging apparatus in real time, and the adjusted scanning protocol is used to continue the scanning and imaging operation on the scanning object. In this embodiment, the scanning protocol adopted by the medical imaging device is adjusted in real time by using the adjusting module 13, so that the quality of the image collected by the medical imaging device can be effectively improved in time by adjusting the scanning protocol in time when the collected image is unqualified.

Fig. 13 is a block diagram of the adjustment module shown in fig. 12. As shown in fig. 13, in an embodiment, the adjusting module 13 may further be configured to modify, delete and/or add protocol parameters in the invoked standard scanning protocol to form a real-time scanning protocol, and then continue to perform scanning imaging operations on the scanned object according to the real-time scanning protocol. For example, the adjusting module 13 may include a modifying unit 131, a deleting unit 132, and an adding unit 133; the modifying unit 131 may be configured to modify a protocol parameter in a scanning protocol used by the current medical imaging apparatus, the deleting unit 132 may be configured to delete a protocol parameter in a scanning protocol used by the current medical imaging apparatus, and the adding unit 133 may be configured to add a protocol parameter in a scanning protocol used by the current medical imaging apparatus. In this embodiment, the currently-used scanning protocol can be timely adjusted to form a real-time scanning protocol by modifying, deleting and/or adding operations according to actual conditions such as patient conditions, treatment factors, the current operating state of the medical imaging device and various other environmental parameters, and the currently-used scanning protocol is subsequently replaced by the real-time scanning protocol to continue the current scanning imaging operation, so that the quality of images acquired by the medical imaging device in the scanning imaging operation can be effectively improved, and the scanning imaging operation failure aiming at the current bed caused by the fact that the scanning protocol is not in accordance with the actual conditions can be avoided.

FIG. 14 is a block diagram of a medical imaging device that adjusts a scan protocol based on image quality parameters for scan imaging in one embodiment. As shown in fig. 14, based on the structure shown in fig. 13 and the related technical content, the medical imaging apparatus of this example may further include a confirmation module 17, where the confirmation module 17 may be configured to confirm the adjusted scanning protocol and then continue to perform the scanning imaging operation on the scanning object by using the confirmed scanning protocol. The confirming module 17 in this embodiment can confirm and recheck the adjustment operation of the scanning protocol to ensure that the adjusted scanning protocol conforms to the actual situation, and avoid the occurrence of the real-time scanning protocol that does not conform to the current situation due to the adjustment error from being applied to the specific scanning imaging operation process.

In another embodiment, in order to further improve the accuracy of the adjustment, a specific adjustment operation may be further defined, for example, the scan protocol parameters may be only adjusted within a defined range, and each currently adjusted scan protocol parameter combination may be defined during the adjustment process, so as to ensure that each scan protocol parameter and its combination are consistent with the actual situation.

In the practical application process, because the patients have great individual difference, the standard scanning protocol is suitable for general population, for example, when the breast scanning is performed on the fat or thin patients, the body thickness of the scanning area has great influence on the quality of scanning imaging; in addition, patient parameters, treatment schemes, medical scanning equipment parameters and the like all have certain influence on the final imaging quality, so the medical imaging device provided by the application realizes real-time adjustment of a scanning protocol to improve the scanning imaging quality and the scanning imaging timeliness based on the comprehensive consideration of various current factors.

For example, as shown in fig. 1, based on a scanning imaging system such as PET, PET-MR, PET-CT or MR, when a scanning positioning image interface and a imaging slice positioning interface (GLI) are displayed on a display screen of an operation console 1 during scanning of a bed on which a patient needs to perform multi-bed scanning, information such as a current protocol scanning progress, a scanned bed and a time progress of scanning of the bed is displayed in the corresponding interface, and an adjustment content is displayed in real time when a current scanning protocol is adjusted, so that an operator can view related information and a process of a current scanning imaging operation. In addition, in order to more intuitively reflect the scanning progress, the human body part information of the scanning object, the states of all scanning beds and the scanning protocol content can be further used. For example, different scanning beds display different covering colors or marks according to different scanning states; for PET-MR or PET-CT equipment, PET and MR or CT protocol parameters, protocol progress and the like can be displayed simultaneously, so that an operator can visually observe the progress of the current scanning imaging operation conveniently, and the scanning protocol is adjusted in real time according to the scanning progress and other displayed related parameter information.
