Description

Technical Field

[0001] The present application relates to the field of medical imaging technology, and more particularly to a method and a DR device for generating digital X-ray photography (DR) images. Background Art

[0002] Digital X-ray (DR) is widely used in clinical examinations due to its advantages, including fast imaging speed, low radiation dose, clear and detailed images, and ability to examine the entire body. It has become one of the primary diagnostic aids for doctors. The DR diagnostic process involves a technician first taking an image on the DR device and reviewing the results. The images are then sent to a picture archiving system (PACS), where the doctor reviews the images and makes a diagnosis.

[0003] However, in actual situations, the following problems have been discovered: after the DR device acquires image data for DR imaging, the image data is displayed normally on the display on the DR device side, but the image data is displayed abnormally on the display on the PACS side (such as the image is too white or too black, or other conditions such as inappropriate brightness and contrast do not meet the requirements for diagnosis of the disease); or, conversely, after the DR device acquires image data for DR imaging, the image data is displayed abnormally on the display on the DR device side, but the image data is displayed normally on the display on the PACS side.

[0004] Since the imaging effect of DR images is the most important part of DR image diagnosis, if the above problem occurs, that is, the DR image displayed on the DR device or PACS is abnormal, it will be detrimental to the diagnosis of the disease.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more apparent, an exemplary embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in this invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0029] The general diagnostic process of DR is as follows: first, the technician takes a picture on the DR device and browses the results, then sends the image to the PACS, where the diagnostic doctor views the image for diagnosis. However, since the displays used on the DR device and PACS are often different, the DR device generally uses an ordinary display, while the PACS generally uses a grayscale display, and the display curves of the two will be different. When the display curves on the two ends are very different, the display effects of the images on both sides, including brightness and contrast, will be different. Therefore, it is possible that the display on the DR device is normal, but the image is abnormal when sent to the PACS; or the image is normal on the PACS, but abnormal on the DR device.

[0030] In order to solve the above problems, the present application provides a solution for generating DR images, which is described below with reference to the accompanying drawings.

[0031] Figure 1 FIG. 1 is a schematic flow chart of a method 100 for generating a DR image according to an embodiment of the present application. Figure 1As shown, the method 100 for generating a DR image may include the following steps:

[0032] In step S110, a first user input or a second user input is received. The first user input indicates entering a first settings interface, while the second user input indicates entering a second settings interface. The first settings interface corresponds to a first scenario, while the second settings interface corresponds to a second scenario. The first scenario is that the display of the original DR image generated based on the original image data from the DR device does not meet the requirements on the first display of the DR device, but does meet the requirements on the second display of the image archiving system. The second scenario is that the display of the original DR image does not meet the requirements on the second display, but does meet the requirements on the first display. When the first user input is received, step S120 is performed; when the second user input is received, step S130 is performed.

[0033] In step S120, in response to receiving the first user input: a first setting interface is displayed, on which a plurality of selectable first gears are displayed, each first gear corresponding to a first brightness curve; a third user input is received, the third user input indicating a target first gear selected by the user from the plurality of first gears, the first brightness curve corresponding to the target first gear is used to transform the original image data to obtain first image data, so that a first DR image generated based on the first image data and displayed on the first display meets the requirements.

[0034] In step S130, in response to receiving a second user input: a second setting interface is displayed, on which a plurality of selectable second gears are displayed, each second gear corresponding to a second brightness curve; a fourth user input is received, the fourth user input indicating a target second gear selected by the user from the plurality of second gears, the second brightness curve corresponding to the target second gear is used to transform the original image data to obtain second image data, so that a second DR image generated based on the second image data and displayed on the second display meets the requirements.

[0035] In an embodiment of the present application, after a user (such as a service personnel) determines the problem scenario, user input can be performed (user input is performed through virtual buttons on the user interface, and / or user input is performed through physical buttons on the interactive device of the DR device side) to enter the corresponding setting interface for solving the problem of abnormal display on the DR device side or the PACS side. Generally, service personnel determine the problem scenario through feedback from medical staff such as doctors. For example, after the manufacturer or seller of DR equipment sells the DR equipment to the hospital, it will regularly send service personnel to the hospital to understand the use of the equipment, or send service personnel to the hospital to understand the use of the equipment when receiving customer requests. Medical staff can feedback the problems that arise to the service personnel based on the use of the DR equipment. When any of the two scenarios mentioned above in this application occurs, the service personnel can perform user input on the interactive device of the DR device to enter the setting interface for solving the problem in the scenario.

[0036] Generally, the setting interface is displayed on the display of the DR device. The problem scenarios include a first scenario and a second scenario. Accordingly, the first user input indicates entering the first setting interface, and the second user input indicates entering the second setting interface, wherein the first setting interface corresponds to the first scenario, and the second setting interface corresponds to the second scenario. The first scenario is: the display of the original DR image generated based on the original image data from the DR device does not meet the requirements on the first display of the DR device, but the display on the second display of the PACS does meet the requirements; the second scenario is: the display of the original DR image on the second display does not meet the requirements, but the display on the first display does meet the requirements. Here, meeting the requirements can be understood as: the displayed DR image meets the doctor's diagnosis requirements, such as the display parameters such as the brightness and contrast of the DR image are within the preset range. Accordingly, not meeting the requirements can be understood as: the displayed DR image does not meet the doctor's diagnosis requirements, such as the display parameters such as the brightness and contrast of the DR image are not within the preset range.

[0037] After receiving user input, a corresponding setting interface can be entered based on the user input. In response to receiving the first user input as described in step S120, a first setting interface is displayed. The first setting interface is provided to resolve the problem in the first scenario. Since the first scenario is that the display of the original DR image generated based on the original image data from the DR device does not meet the requirements on the first display of the DR device, but meets the requirements on the second display of the PACS, the purpose of the settings on the first setting interface is to ensure that the DR image displayed on the DR device meets the requirements.

[0038] In an embodiment of the present application, a plurality of selectable first gears are displayed on the first setting interface, and each first gear corresponds to a first brightness curve. The first brightness curve can transform the original image data obtained by the DR device end to obtain the transformed data, and the display of the DR image generated based on the transformed data on the display of the DR device end can meet the requirements, that is, it can be displayed normally. Although under normal circumstances, the display used by the customer (hospital) on the DR device end (that is, the first display mentioned above) is an ordinary display (that is, a general color display), and the display used on the PACS end (that is, the second display mentioned above) is a grayscale display, the manufacturers, models, etc. of the ordinary displays used by different customers on the DR device end may be different, and the manufacturers, models, etc. of the grayscale displays used by different customers on the PACS end may also be different. Therefore, in order to cover different situations, multiple first gears are provided, and the first brightness curve corresponding to each first gear provides a mapping relationship, which can eliminate the display difference between an ordinary display and a grayscale display - because the same original image data is displayed normally on the grayscale display, but is displayed abnormally on the ordinary display. The original image data can be transformed based on the mapping relationship to obtain new image data, and the display effect of the new image data on the ordinary display will be consistent with or similar to the display effect of the original image data on the grayscale display.

[0039] Specifically, an image data conversion relationship can be established based on the display difference (such as brightness difference, contrast difference, or both) between a normal display and a grayscale display, that is, the first gear is obtained.

[0040] In one example, multiple first gears can be pre-set based on the following goal: to ensure that the aforementioned first DR image (i.e., a DR image generated based on new image data to be displayed on a display on the DR device end, where the new image data is obtained by transforming the original image data using a brightness curve corresponding to the first gear) and the original DR image (i.e., a DR image generated based on the original image data) have equal or similar brightness for the same grayscale. In this example, the image data transformation relationship is established based on the brightness difference between a conventional display and a grayscale display.

[0041] In another example, the multiple first gears can be pre-set based on the goal of ensuring that the just noticeable differences (JNDs) corresponding to brightness changes between adjacent grayscale levels in the first DR image and the original DR image are equal or similar. In this example, the image data conversion relationship is established based on the contrast difference between a standard display and a grayscale display.

[0042] In another example, multiple first gears can be pre-set based on the following goal: starting with a grayscale with equal brightness for the first DR image and the original DR image, the just noticeable differences (JNDs) corresponding to brightness changes between adjacent grayscales of the first DR image and the original DR image are equal or similar. That is, an initial mapping relationship is established based on the equal brightness of the image grayscales, and then mapping relationships for other grayscales are established based on the just noticeable differences (JNDs) corresponding to brightness changes between adjacent grayscales of the image. In this example, the image data conversion relationship is established based on the brightness and contrast differences between a conventional display and a grayscale display.

[0043] In this way, the user can select a gear that meets the display difference between the DR-end display and the PACS-end display currently used by the customer as the target gear through the third user input from multiple first gears. In this way, in subsequent DR imaging, every time the DR device acquires the original image data, the original image data can be transformed based on the target gear to obtain new image data. The display effect of the DR image generated based on the new image data (called the first DR image) on the DR-end display will be consistent or similar to the display effect of the DR image generated based on the original image data (called the original DR image) on the PACS-end display, thereby avoiding the problem of affecting the diagnosis of the disease due to abnormal DR image display.

[0044] Here, the original image data mentioned above can be understood as the image data obtained by the DR device after being processed by the conventional DR process and can be imaged to be displayed on the display.

[0045] When the second user input is received, as described in step S130, a second settings interface is displayed in response to the second user input. The second settings interface is designed to address the problem in the second scenario. Since the second scenario is that the original DR image generated based on the original image data from the DR device meets the requirements on the first display of the DR device, but does not meet the requirements on the second display of the PACS, the settings on the second settings interface are intended to ensure that the DR image displayed on the PACS meets the requirements.

[0046] In an embodiment of the present application, a second setting interface displays a plurality of selectable second gears, each of which corresponds to a second brightness curve. The second brightness curve can transform the original image data obtained by the DR device to obtain transformed data. The DR image generated based on the transformed data can be displayed on the display of the PACS device to meet the requirements, that is, it can be displayed normally. Although in general, the display used by the customer (hospital) on the DR device is a normal display and the display used on the PACS is a grayscale display, different customers may use different displays on the DR device, and different customers may also use different displays on the PACS. Therefore, in order to cover different situations, multiple second gears are provided, and the second brightness curve corresponding to each second gear provides a mapping relationship. The mapping relationship can eliminate the display difference between a grayscale display and a normal display - because the same original image data is displayed normally on the normal display, but not normally on the grayscale display. Based on the mapping relationship, the original image data can be transformed to obtain new image data, and the display effect of the new image data on the grayscale display will be consistent or similar to the display effect of the original image data on the normal display.

[0047] Specifically, an image data conversion relationship can be established based on the display difference (such as brightness difference, contrast difference, or both) between a normal display and a grayscale display, that is, the second gear is obtained.

[0048] In one example, multiple second levels can be pre-set based on the following goal: to ensure that the aforementioned second DR image (i.e., a DR image generated based on new image data to be displayed on a display at the PACS device, where the new image data is obtained by transforming the original image data using a brightness curve corresponding to the second level) and the original DR image (i.e., a DR image generated based on the original image data) have equal or similar brightness for the same grayscale. In this example, the image data transformation relationship is established based on the brightness difference between a conventional display and a grayscale display.

[0049] In another example, the plurality of second gears may be pre-set based on the goal of ensuring that the just noticeable differences (JNDs) corresponding to brightness changes between adjacent grayscale levels in the second DR image and the original DR image are equal or similar. In this example, the image data conversion relationship is established based on the contrast difference between a standard display and a grayscale display.

[0050] In another example, multiple second gears can be pre-set based on the following goal: starting with a grayscale with equal brightness for the second DR image and the original DR image, the just noticeable differences (JNDs) corresponding to brightness changes between adjacent grayscales in the second DR image and the original DR image are equal or similar. That is, an initial mapping relationship is established based on the equal brightness of the image grayscales, and then mapping relationships for other grayscales are established based on the just noticeable differences (JNDs) corresponding to brightness changes between adjacent grayscales in the image. In this example, the image data conversion relationship is established based on the brightness and contrast differences between a standard display and a grayscale display.

[0051] In this way, the user can select a gear that meets the display difference between the DR display and the PACS display currently used by the customer as the target gear from multiple second gears through the fourth user input. In this way, in subsequent DR imaging, every time the DR device acquires the original image data, the original image data can be transformed based on the target gear to obtain new image data. The display effect of the DR image generated based on the new image data (called the second DR image) on the PACS display will be consistent or similar to the display effect of the DR image generated based on the original image data (called the original DR image) on the DR device display, thereby avoiding the problem of affecting the diagnosis of the disease due to abnormal DR image display.

[0052] Therefore, the method 100 for generating DR images according to the embodiment of the present application can solve the problem of inconsistency between the DR images displayed on the DR device side and the PACS side, and avoid the problem of affecting the diagnosis of the disease due to abnormal display of DR images on the DR device side or the PACS side.

[0053] In an embodiment of the present application, image data transformation is implemented using gears, with each gear representing an approximate brightness curve (the horizontal axis of the brightness curve is the input level, and the vertical axis is the brightness value). The number of gears can be set according to actual needs. The PACS can be configured with several gears, and each gear can be established based on a different DICOM curve (DICOM stands for Digital Imaging and Communication in Medicine, an international standard for medical image processing and communication. The algorithm curve used by DICOM is used for image grayscale correction and adjustment to ensure the reliability and accuracy of medical images). For example, the DICOM200 curve is one gear, the DICOM300 curve is one gear, and the DICOM400 curve is one gear. Alternatively, the display curves of commonly used monitors on the market can be statistically analyzed and clustered to obtain the shapes of the brightness curves at different gears. For the DR device, several gears can also be configured, and the display curves of commonly used monitors on the market can be statistically analyzed and clustered to obtain the shapes of the brightness curves at different gears. Alternatively, the average brightness curve of the monitor model used on the device can be calculated and used as the approximate brightness curve for the device and configured in the software.

[0054] In one embodiment of the present application, a check box control is displayed next to each of the multiple first gears on the first setting interface, and the third user input mentioned above can be used to select the target first gear through the check box control. Figure 2 The figure shows the display and selection of multiple first gears. The multiple first gears include DICOM 400, DICOM 200, Medium Brightness, and Low Brightness. Each gear includes a square box for user selection.

[0055] In this embodiment, multiple first gears can be displayed at once on the first setting interface, making it clear at a glance. For example, the name of each gear can be displayed, and multiple gears can be displayed in a column. There is a check box control in front of each gear, for example, the check box control is a small square box. When the user clicks the check box, a "√" ( Figure 2The number shown is "·", and it can also be any other suitable form, such as "x", as long as it reflects that it is selected), indicating that the gear corresponding to the check box is selected. If the user makes an error and selects an option that he does not want to select, he can also re-click the check box he wants to select. At this time, "√" appears in the re-selected check box, indicating that the gear corresponding to the check box is selected, and the "√" in the check box that was previously selected by error can disappear automatically. Of course, this is the case of "single selection" gear. In subsequent embodiments, there is also the case of "multiple selection" gears, which involves the scenario of gear fusion, which will be described in a later embodiment. In general, the user selects the target gear through the check box control, which is simple to operate and very convenient.

[0056] In another embodiment of the present application, multiple first gears on the first setting interface can be displayed in a drop-down box control, and the third user input mentioned above can be used to select the target first gear through the drop-down box control. Figure 3 The figure shows how to display and select multiple first gears. The multiple first gears are hidden in a drop-down box. When the drop-down box is clicked, an expanded window appears below the drop-down box to display multiple first gears, such as DICOM 400 gear, DICOM 200 gear, medium brightness gear, and low brightness gear. When the user clicks one of the gears, the gear appears in the drop-down box, and the expanded window below the drop-down box closes.

[0057] In this embodiment, multiple first gear positions on the first settings interface can be displayed by clicking a drop-down box. For example, after clicking the drop-down box, the name of each gear position can be displayed below the drop-down box. Multiple gear positions can be displayed in a column. When the user clicks the name of any gear position, the gear position corresponding to that name is selected. If the user makes an error and selects an option they did not intend to select, they can click the drop-down box again. The name of each gear position will be displayed below the drop-down box. The user can then click the name of the gear position they wish to select. The previous error will be invalidated when the gear position name is reselected. Overall, the user can select the target gear position through the drop-down box control, which is simple and convenient to operate. It is more suitable for scenarios with a large number of gear positions or scenarios with strict restrictions on interface size.

[0058] In an embodiment of the present application, multiple selectable first gears are displayed in a gear selection area on the first setting interface, and the first setting interface also includes an image preview area, wherein: when one of the multiple first gears is selected, the original image data is transformed based on the first brightness curve corresponding to the selected gear to obtain transformed image data, and a DR preview image is generated based on the transformed image data and displayed in the image preview area, so that the user can confirm whether the currently selected gear meets the requirements; when the DR preview image meets the requirements, the fifth user input is received to save the current settings and close the first setting interface; when the DR preview image does not meet the requirements, the third user input is received again to select another gear from the multiple first gears.

[0059] In this embodiment, the first settings interface includes not only a gear selection area but also an image preview area. After selecting a gear, the user can use the image displayed in the image preview area to determine whether the currently selected gear is appropriate, that is, whether the DR image displayed on the DR device meets the user's requirements. Specifically, raw image data corresponding to a historical DR image can be obtained, and this raw image data can be transformed based on the brightness curve corresponding to the selected gear to obtain transformed image data. A DR preview image is generated based on the transformed image data and displayed in the image preview area of ​​the first settings interface. Since the first settings interface is typically displayed on the DR device's display, displaying the DR preview image on the first settings interface, i.e., displaying the DR preview image on the DR device's display, allows the user to easily determine whether the currently displayed DR preview image meets the user's requirements. If so, the selected gear is appropriate, and the user can save the current settings and exit the first settings interface. For example, a "Save" button and a "Close" button can be displayed on the first settings interface. The user can click these buttons as the fifth user input to save the selected gear and exit the settings interface. If the DR preview image does not meet the user's requirements, the user can reselect the gear. The DR preview image corresponding to the new gear will then be displayed again in the image preview area, allowing the user to confirm whether the gear selection is appropriate. For experienced service personnel, it may be possible to select the most appropriate gear in one try, while for less experienced service personnel, it may take multiple attempts to select the most appropriate gear. Therefore, in this embodiment, the user can select the most suitable gear through the preview image, which provides great convenience for less experienced service personnel.

[0060] In some cases, after previewing the image, you may find that each gear cannot meet your needs. To address this situation, the first setting interface may also include a gear fusion area, in which at least two of the aforementioned multiple gears can be merged, and the new gear obtained after fusion may meet your needs.

[0061] In one embodiment of the present application, a gear fusion control and a fusion selection control are displayed in the gear fusion area, wherein: when each of the multiple first gears has been selected and the DR preview images corresponding to each gear do not meet the requirements, a sixth user input is received, and the sixth user input is used to select the gear fusion control; when the gear fusion control is selected, the multiple first gears displayed in the gear selection area become unselectable or invalid, and the fusion selection control is used to provide a selection of at least two gears; a seventh user input is received, and the seventh user input is used to select at least two first gears to be fused through the fusion selection control, and the selected at least two first gears are fused to obtain a new gear, and the new gear corresponds to a new first brightness curve for image data transformation.

[0062] In this embodiment, the gear fusion area displays a gear fusion control and a fusion selection control. When the gear fusion control is selected, it indicates that the user wishes to perform gear fusion, that is, the multiple gears displayed in the gear selection area cannot meet the needs. At this time, it is necessary to reselect at least two gears to be fused in the fusion selection control in the gear fusion area. Therefore, the multiple first gears displayed in the gear selection area become unselectable (for example, the check box control in front of each gear in the aforementioned implementation becomes unclickable) or the selection is invalid (for example, the check box control in front of each gear in the aforementioned implementation becomes clickable, but the click is ineffective). Since the fusion selection control can provide gear selection again, the user can select at least two gears to be fused through the fusion selection control through the seventh user input to perform gear fusion and obtain a new gear.

[0063] For example, the gear fusion area may display at least two fusion selection controls, each of which provides multiple first gears in the form of a drop-down box control (the multiple first gears here may be the same as the multiple first gears provided in the gear selection area), and the seventh user input selects the first gear to be fused through these drop-down box controls. Figure 4 As shown, each fusion selection control provides multiple first gears in the form of a drop-down box control. The user can select a first gear through one of the drop-down box controls, and then select another first gear through another drop-down box control. The two selected first gears can be fused to obtain a new gear.

[0064] In another embodiment of the present application, a gear fusion control is displayed in the gear fusion area; when each of the multiple first gears has been selected and the DR preview images corresponding to each gear do not meet the requirements, a sixth user input is received, and the sixth user input is used to select the gear fusion control; when the gear fusion control is selected, the multiple first gears displayed in the gear selection area change from a single selection state to a multiple selection state, and an eighth user input is received, and the eighth user input is used to select at least two gears from the multiple first gears, and the at least two selected first gears are fused to obtain a new gear, and the new gear corresponds to a new first brightness curve for image data transformation.

[0065] This embodiment differs from the previous embodiment in that the gear fusion area only includes the gear fusion control, not the fusion selection control. That is, rather than making the fusion selection area unavailable or invalid, and rather than using the fusion selection control to select the gear to be fused, the gear to be fused is selected from the gear selection area. Therefore, when the gear fusion control is selected, the multiple first gears displayed in the gear selection area change from a single selection state to a multiple selection state, and the user can select at least two gears from the multiple first gears displayed in the gear selection area to fuse together to form a new gear.

[0066] After obtaining the gears to be merged, the gear fusion is to be performed. The gear fusion can be performed based on the weighted coefficient. For example, two gears are selected for fusion. The weighted coefficient of the first gear is k1, and the weighted coefficient of the second gear is k2. The gear fusion can be performed based on the weighted coefficient. For example, Figure 5 As shown, the brightness curves corresponding to the gears a and b are the upper and lower red curves, which are fused to obtain the fused gear, and the brightness curve corresponding to the fused gear is the green curve.

[0067] In one embodiment of the present application, the at least two selected first gears are weighted based on a preset default weighting coefficient when the gear is merged. In this embodiment, the user only needs to select the gear to be merged. The weighting coefficient is the system default and does not require user selection or setting. For example, when selecting two gears to merge, the system defaults to a weighting coefficient of 0.5 for each gear, and so on.

[0068] In another embodiment of the present application, the at least two selected first gears are fused based on user-set weighting coefficients, wherein the gear fusion area further includes a fusion degree setting control, which is used to receive a ninth user input, and the ninth user input is used to set weighting coefficients for the at least two selected first gears. In this embodiment, the user needs to select the gears to be fused and also needs to set the weighting coefficients for each gear. In this case, the gear fusion area on the first settings interface may also include a fusion degree setting control, and the user can set the weighting coefficients for each gear to be fused based on the fusion degree setting control.

[0069] For example, the fusion selection control provides two gear selections, and the fusion degree setting control is displayed in the form of a drag bar. When the drag mark on the drag bar is dragged to a specific position of the drag bar, the weighting coefficient corresponding to the position of the drag bar is used as the weighting coefficient of one of the two gears, and the sum of the weighting coefficient of the other gear and the weighting coefficient corresponding to the position of the drag bar is 1. For example, Figure 6 As shown, each fusion selection control provides multiple first gears in the form of a drop-down box control. The user can select a first gear through one of the drop-down box controls, and then select another first gear through another drop-down box control. In addition, the user performs a drag operation on the drag marker on the drag bar. When the user stops dragging, the drag marker is at a certain position on the drag bar, and the position corresponds to a weighting coefficient value. The value is 0.4, for example. Then, of the two gears, the weighting coefficient of the first gear is 0.4, and the weighting coefficient of the second gear is 0.6.

[0070] In an embodiment of the present application, after obtaining a new gear through fusion, method 100 may further include: transforming the original image data based on the brightness curve corresponding to the new gear to obtain transformed image data, generating a DR preview image based on the transformed image data and displaying it in the image preview area so that the user can confirm whether the currently selected gear meets the requirements; when the DR preview image meets the requirements, receiving the fifth user input to save the current settings and close the first setting interface; when the DR preview image does not meet the requirements, receiving the ninth user input again to reset the weighting coefficient.

[0071] In this embodiment, after setting the weighting coefficients, the user can use the image displayed in the image preview area to determine whether the currently set weighting coefficients are appropriate, that is, whether the DR image displayed on the DR device meets the requirements. Specifically, the original image data corresponding to the historical DR image can be obtained, and the original image data can be transformed based on the brightness curves and weighting coefficients corresponding to the at least two selected gears to obtain transformed image data. Based on the transformed image data, a DR preview image is generated and displayed in the image preview area of ​​the first settings interface. Since the first settings interface is typically displayed on the DR device's display, the DR preview image is displayed on the first settings interface, that is, displayed on the DR device's display, allowing the user to naturally determine whether the currently displayed DR preview image meets the requirements. If so, the selected weighting coefficients are appropriate, and the current settings can be saved and the first settings interface can be exited. If the DR preview image does not meet the requirements, the user can reset the weighting coefficients or even reselect the gear to be fused. The DR preview image corresponding to the new gear is then displayed again in the image preview area, allowing the user to confirm whether the gear and weighting coefficient selections are appropriate.

[0072] Figure 7 That is, it shows the combination of the above-mentioned multiple embodiments. Figure 7 As shown, the first setting interface includes a gear selection area (with Figure 2 similar to that shown), the gear fusion area for gear fusion (similar to Figure 6 Similarly), it also includes an image preview image below. Through such a setting interface, the user can conveniently implement the setting of the first gear to solve the problem in the first scene.

[0073] In yet another embodiment, a new gear can be obtained through gear adjustment rather than gear fusion. In this embodiment, the first setting interface also includes a gear adjustment area, wherein: when each of the multiple first gears has been selected and the DR preview images corresponding to each gear do not meet the requirements, the gear adjustment area displays the first brightness curve corresponding to the currently selected first gear, and multiple draggable points are displayed on the first brightness curve; the tenth user input is received, and the tenth user input is used to drag at least one of the multiple draggable points from its original position to a new position to form a new first brightness curve, thereby obtaining a new gear.

[0074] For example, in one example, Figure 8 As shown, the red curve is the brightness curve corresponding to the original gear position, and there are three draggable points on it. The user can drag them arbitrarily. The new curve shown in the figure is obtained by dragging the upper end point downward, that is, the green curve shown in the figure. In another example, Figure 9 As shown, the red curve is the brightness curve corresponding to the original gear position, and three draggable points are displayed on it. The user can drag them arbitrarily. The figure shows that a new curve is obtained by dragging the middle point, that is, the green curve shown in the figure.

[0075] In this embodiment, a new brightness curve, i.e., a new gear, is obtained by directly fine-tuning the brightness curve. The fine-tuned brightness curve may be a gear selected from the gear selection area, or may be one of at least two gears selected from the fusion selection area.

[0076] In an embodiment of the present application, after obtaining the new gear, method 100 may further include: transforming the original image data based on the brightness curve corresponding to the new gear to obtain transformed image data, generating and displaying a DR preview image based on the transformed image data in the image preview area, so that the user can confirm whether the currently selected gear meets the requirements; when the DR preview image meets the requirements, receiving the fifth user input to save the current settings and close the first setting interface; when the DR preview image does not meet the requirements, receiving the tenth user input again to drag the draggable point again to form a new brightness curve.

[0077] In this embodiment, after the user obtains a new gear position through gear adjustment, they can use the image displayed in the image preview area to determine whether the newly adjusted gear position is suitable, that is, whether the DR image displayed on the DR device meets their requirements. Specifically, the original image data corresponding to the historical DR image can be obtained, and this original image data can be transformed based on the brightness curve corresponding to the obtained new gear position to obtain transformed image data. Based on the transformed image data, a DR preview image is generated and displayed in the image preview area of ​​the first settings interface. Since the first settings interface is typically displayed on the DR device's display, the DR preview image is displayed on the first settings interface, that is, the DR preview image is displayed on the DR device's display, so the user can naturally determine whether the currently displayed DR preview image meets their requirements. If so, the newly adjusted gear position is suitable, and the current settings can be saved and the first settings interface can be exited. If the DR preview image does not meet their requirements, the user can readjust the gear position or change the gear position and adjust it again. The DR preview image corresponding to the new gear position is then displayed again in the image preview area to confirm whether the new gear position is suitable.

[0078] Various examples of performing settings based on the first setting interface to solve problems in the first scenario are described in detail above. Various examples of performing settings based on the second setting interface to solve problems in the second scenario are described below.

[0079] In one embodiment of the present application, a check box control is displayed next to each of the multiple second gear positions on the second setting interface, and the fourth user input mentioned above can be used to select the target second gear position through the check box control (similar to the display of multiple first gear positions on the first setting interface, see Figure 2 ). In this embodiment, multiple second gears on the second setting interface can be displayed at once, which is clear at a glance. For example, the name of each gear can be displayed, and multiple gears can be displayed in a column. There is a check box control in front of each gear. For example, the check box control is a small square box. When the user clicks the check box, "√" (or any other suitable symbol indicating that it is selected) appears in the check box, indicating that the gear corresponding to the check box is selected. If the user makes an error and selects an option that he did not want to select, he can also re-click the check box he wants to select. At this time, "√" appears in the re-selected check box, indicating that the gear corresponding to the check box is selected, and the "√" in the check box that was previously selected by mistake can automatically disappear. Overall, the user selects the target gear through the check box control, which is simple to operate and very convenient.

[0080] In another embodiment of the present application, multiple second gears can be displayed in a drop-down box control on the second setting interface, and the fourth user input mentioned above can be used to select the target second gear through the drop-down box control (similar to the display of multiple first gears on the first setting interface, see Figure 3 ). In this embodiment, multiple second gears on the second setting interface can be displayed by clicking the drop-down box. For example, after clicking the drop-down box, the name of each gear can be presented below the drop-down box, and multiple gears can be displayed in a column. When the user clicks on the name of any gear, it indicates that the gear corresponding to the name is selected. If the user makes an error and selects an option that he originally did not want to select, he can also click the drop-down box again. The name of each gear can be presented below the drop-down box. At this time, the user can click the name of the gear he wants to select. The previous error operation will become invalid as the gear name is reselected. In general, the user can select the target gear through the drop-down box control, which is simple to operate and very convenient. It is more suitable for scenarios with many gears or scenarios with strict restrictions on the interface size.

[0081] In some cases, the user may find that each gear cannot meet the needs based on the differences between the DR-end display and the PACS-end display that he knows. In response to this situation, the second setting interface may also include a gear fusion area. In the gear fusion area, it is possible to achieve the fusion of at least two of the aforementioned multiple gears, and the new gear obtained after the fusion is likely to meet the needs. Alternatively, in response to this situation, the second setting interface may also include a gear adjustment area. In the gear adjustment area, a new gear can be obtained by adjusting the brightness curve corresponding to the existing gear, and the new gear is likely to meet the needs. Among them, the method of performing gear fusion in the gear fusion area and the method of performing gear adjustment in the gear adjustment area are similar to the methods described in the previous description of the first setting interface. For the sake of brevity, they will not be repeated here.

[0082] In some hospitals, a DR device may correspond to more than one PACS, meaning that a DR device may need to transmit data to at least two PACSs. ​​In this case, method 100 may further include: displaying a third setup interface before displaying the second setup interface, wherein the third setup interface displays a node list, each node in the node list corresponding to a PACS; receiving an eleventh user input indicating a target PACS selected by the user from the node list; and displaying a second setup interface corresponding to the target PACS in response to receiving the eleventh user input.

[0083] In this embodiment, since a single DR device can correspond to more than one PACS, the displays on each PACS may differ slightly. In this case, the PACS node can be selected using the third setup interface, and the second setup interface can be displayed for each selected PACS node to select the second level. Of course, it is also possible that the displays on each PACS are identical. In this case, the third setup interface can be omitted and the configuration can be completed directly on the second setup interface. The final settings will apply to each PACS node.

[0084] For example, Figure 10 As shown, a storage server list is shown, which shows multiple node names (each node can be understood as a PACS terminal, of course, it can also be other servers). The user can select the node to be set, and then click "Image Display Correction" to enter the second setting interface mentioned above.

[0085] In general, after the first setting interface is set up, the problem in the first scenario can be solved, such as Figure 11As shown: the original data (i.e., the data in Figure a) is displayed normally on the display B at the PACS end. The data in Figure a is transformed by the image data transformation function (i.e., the first brightness curve corresponding to the first gear of the target selected by the user as mentioned above) to obtain the data in Figure b. The data in Figure b is also displayed normally on the display A at the Droc end (i.e., the DR end).

[0086] Similarly, after the second setting interface is set up, the problem in the second scenario can be solved, such as Figure 12 As shown in the figure: the original data (i.e., the data in Figure a) is displayed normally on the display A of the Droc end (i.e., the DR end), and the data in Figure a is transformed by the image data transformation function (i.e., the second brightness curve corresponding to the second gear of the target selected by the user as mentioned above) to obtain the data in Figure b, and the display of the data in Figure b on the display B of the PACS end also becomes normal.

[0087] Based on the above description, the method 100 for generating DR images according to an embodiment of the present application can solve the problem of inconsistency between the DR images displayed on the DR device side and the PACS side, and avoid the problem of affecting the diagnosis of the disease due to abnormal display of DR images on the DR device side or the PACS side.

[0088] The functions implemented by the above method can also be enabled selectively. For example, after obtaining the original image data, the user can determine whether to enable the display consistency function. If the user does not enable it, a DR image is generated based on the original image data; if the user enables it, the image data is transformed according to the user's settings to generate a new DR image.

[0089] The following combination Figure 13 A DR device according to another aspect of the present application is described. Figure 13 FIG. 1 shows a schematic structural block diagram of a DR device 1300 according to an embodiment of the present application. Figure 13As shown, DR device 1300 may include a memory 1310, a processor 1320, and a display 1340. Memory 1310 is used to store an executable program, and processor 1320 is used to execute the executable program, causing processor 1320 to perform the aforementioned method 100 for generating digital radiographic DR images according to an embodiment of the present application. Processor 1320 is also used to control display 1330 to output a display interface. The specific operations and display interface of method 100 for generating digital radiographic DR images have been described in detail above. Those skilled in the art will understand the structure and operation of DR device 1300 in conjunction with the above description, and for the sake of brevity, a detailed description will not be given here. In addition to the aforementioned structure, DR device 1300 may also include an X-ray generator and detector required to implement DR functions. The X-ray generator is used to generate X-rays, emit X-rays toward a target tissue site, and control the X-rays to pass through the target tissue site. The detector is used to receive X-rays that have passed through the target tissue site and process the X-rays to obtain image data.

[0090] The DR device 1300 according to the embodiment of the present application can solve the problem of inconsistency between DR images displayed on the DR device side and the PACS side, and avoid the problem of affecting disease diagnosis due to abnormal display of DR images on the DR device side or the PACS side.

[0091] The following combination Figure 14 A method 1400 for generating a medical image according to another aspect of the present application is described. Figure 14 As shown, the method 1400 for generating a medical image may include the following steps:

[0092] In step S1410, a first user input or a second user input is received. The first user input indicates entering a first settings interface, while the second user input indicates entering a second settings interface. The first settings interface corresponds to a first scenario, while the second settings interface corresponds to a second scenario. The first scenario is that the display of the original medical image generated based on the original image data from the medical device does not meet the requirements on the first display of the medical device, but does meet the requirements on the second display of the server. The second scenario is that the display of the original medical image does not meet the requirements on the second display, but does meet the requirements on the first display. When the first user input is received, step S1420 is performed; when the second user input is received, step S1430 is performed.

[0093] In step S1420, in response to receiving the first user input: a first setting interface is displayed, on which a plurality of selectable first gears are displayed, each first gear corresponding to a first brightness curve; a third user input is received, the third user input indicating a target first gear selected by the user from the plurality of first gears, the first brightness curve corresponding to the target first gear is used to transform the original image data to obtain first image data, so that the first medical image generated based on the first image data and displayed on the first display meets the requirements.

[0094] In step S1430, in response to receiving a second user input: a second setting interface is displayed, on which a plurality of selectable second gears are displayed, each second gear corresponding to a second brightness curve; a fourth user input is received, the fourth user input indicates a target second gear selected by the user from the plurality of second gears, and the second brightness curve corresponding to the target second gear is used to transform the original image data to obtain second image data, so that a second medical image generated based on the second image data and displayed on the second display meets the demand.

[0095] Method 1400 for generating medical images according to an embodiment of the present application is generally similar to method 100 for generating DR images described above, except that: in method 100, the DR image used for display is inconsistent between the display of the DR device and the display of the PACS, with one displaying normally and the other displaying abnormally. Method 1400 is not limited to DR images for display, but can be various medical images (such as ultrasound images). The same medical image is inconsistent between the display of a medical device (such as an ultrasound imaging device) and the display of a server (such as a central server), with one displaying normally and the other displaying abnormally. In other respects, method 1400 is substantially similar to method 100. Therefore, method 1400 can solve the problem of inconsistent medical images displayed on the medical device and the server, avoiding problems that affect disease diagnosis due to abnormal display of medical images on the medical device or server. The specific operations and display interface of method 100 for generating medical images have been described in detail above. Those skilled in the art can understand the operations and display interface of method 1400 in combination with the above. For the sake of brevity, the details will not be repeated here, and only some main contents will be described.

When the drag marker on the drag bar is dragged to a specific position of the drag bar, the weighting coefficient corresponding to the position of the drag bar is used as the weighting coefficient of one of the two gears, and the sum of the weighting coefficient of the other gear of the two gears and the weighting coefficient corresponding to the position of the drag bar is 1.
