Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Medical images such as CT or MR generally include different tomographic images and corresponding positioning images, and positioning lines are displayed on the positioning images to indicate the position of the current tomographic image in the human body, as shown in fig. 1. The tomography image and the positioning image are taken as important bases of medical diagnosis and are relied on by doctors all the time, the traditional image diagnosis work is carried out in an image department of a hospital, and in order to relieve the productivity of image doctors and improve the reuse of medical resources, the medical image can be displayed based on image diagnosis software of mobile Application (Application for short).
However, for a mobile device (such as a mobile phone or a Pad), because of the limitation of the screen size, medical images are not suitable for being displayed according to a multi-sequence layout of a computer, and in order to be able to better and more comprehensively browse the medical images on the mobile device with a smaller screen by using a mobile App, the embodiment of the present application provides a medical image display method and a display device, only one tomographic image is displayed on the screen, and the display position and/or the display size of a corresponding positioning image can be adaptively adjusted according to the relative position of the current tomographic image, so that an imaging doctor can observe the position of the tomographic image on a human body through the positioning image while clearly browsing the tomographic image at a mobile end, thereby facilitating the imaging doctor to find a fine focus and improving the accuracy of image diagnosis.
Referring to fig. 2, a flowchart of a medical image display method provided in an embodiment of the present application is schematically illustrated, where the medical image display method includes the following steps S201 to S202:
s201: in response to a user-triggered image display request, displaying a currently requested first medical image and a second medical image corresponding to the first medical image on an image display window, wherein the first medical image and the second medical image do not overlap.
The present embodiment does not specifically limit the medical images themselves, i.e. the first medical image and the second medical image may be any relevant medical images. To facilitate understanding of the present embodiment, the following specifically describes the present embodiment by taking the first medical image as a tomographic image and the second medical image as a positioning image as an example.
The method comprises the following steps that an image initialization process is carried out, when the image initialization process is concretely implemented, a user can open image diagnosis software installed on the mobile equipment, the image diagnosis software can provide a function for the user to select a sectional image of a certain position of a human body, after the user selects the certain sectional image and triggers an image display request of the selected sectional image through a related function key, the mobile equipment starts to load the sectional image, meanwhile, a positioning image representing the position of the human body where the sectional image is located is loaded, and finally, the sectional image and the positioning image corresponding to the sectional image are displayed on an image display window on a screen of the mobile equipment. Therefore, only one tomographic image and one positioning image are displayed on the screen, so that a clearer image display effect can be achieved.
In addition, in order to avoid the situation that the positioning image blocks the tomography image or the situation that the positioning image blocks the positioning image, the embodiment enables the displayed tomography image not to be overlapped with the positioning image, so that the user can conveniently carry out image diagnosis; furthermore, in order to facilitate the user's finding of a lesion, the display area of the tomographic image should be larger than that of the positioning image.
The medical image loaded by the image initialization generally includes two display modes, one is a horizontal screen display mode as shown in fig. 3, and the other is a vertical screen display mode as shown in fig. 4. In practical applications, a user may switch between the two display modes, for example, when the user rotates the screen, the horizontal screen display shown in fig. 3 may be switched to the vertical screen display shown in fig. 4, or the vertical screen display shown in fig. 4 may be switched to the horizontal screen display shown in fig. 3, and before the switching, the image initialization is performed again.
In this embodiment, when initializing an image, a display area occupied by a tomographic image and a positioning image in an image display window needs to be calculated in advance, and a horizontal screen display mode is taken as an example below:
typically, the image display window is rectangular, while the CT and MR tomographic and scout images are square. Referring to the schematic diagram of the image display window shown in fig. 5, first, a distance (AD or BC) between upper and lower vertexes on the same side in the image display window ABCD is calculated, and a square area is found in the image display window ABCD with the distance as a side length to display a tomographic image a 'B' C 'D'; then, the display area of the positioning image is searched for in other areas, in order to make the user see the positioning image more clearly, the image diagnosis software sets the minimum display side length of the positioning image in advance, and in order to avoid the display area of the positioning image being too large to occupy the display area of the tomographic image, the image diagnosis software also sets the maximum display side length of the positioning image in advance, so that when the tomographic image a 'B' C 'D' is displayed to the left in the image display window ABCD to leave only a right-side free area, or displayed to the right to leave only a left-side free area, or displayed in the middle (left-side or right-middle in the middle) to leave two left and right free areas, the shorter side length of a certain free area should be greater than or equal to the minimum display side length of the positioning image (if the free area does not satisfy the requirement, it can be overcome by reducing the display area of the tomographic image), for finding a square area within the free area for displaying the positioning image.
Of course, when the tomographic image and/or the positioning image are rectangular, the display areas of the tomographic image and the positioning image may be positioned in the image display window in the above manner as long as the requirements that the tomographic image and the positioning image do not overlap and the display area of the tomographic image is larger than the display area of the positioning image are satisfied.
It should be noted that the positioning image may be displayed at the upper left corner, the lower left corner, the upper right corner, the lower right corner, and the like of the image display window, the display position of the positioning image is not limited in this embodiment, and the specific position may be configured in the image diagnosis software in advance or manually selected.
S202: in response to the transformation operation of the first medical image by the user, the display position and/or the display size of the second medical image are adaptively changed according to the transformation of the first medical image in the transformation process of the first medical image.
After the image initialization is completed in step S201, a user may perform a transformation operation, such as a translation operation or a zoom operation, on the displayed first medical image, and in the transformation process of the first medical image, the display position and/or the display size of the second medical image may be automatically adjusted according to the relative position between the second medical image and the first medical image, so as to meet the requirement of the user for browsing the second medical image and the first medical image simultaneously as far as possible on the premise that the first medical image is not blocked.
It can be seen that, in the medical image display method provided in this embodiment, after the user triggers the image display request, the first medical image and the second medical image corresponding to the first medical image that are currently requested are displayed on the image display window, so that the first medical image and the second medical image are not displayed in an overlapping manner, and thus, by displaying only one first medical image on a smaller screen and avoiding mutual occlusion between the images, a clearer image display effect can be achieved, in addition, the user can operate the first medical image according to the browsing requirement, during the transformation process of the first medical image, the display position and/or display size of the second medical image is adaptively adjusted, which maximally satisfies that the user can clearly browse the first medical image at the mobile terminal, and simultaneously, the related information of the first medical image can also be queried through the second medical image, the method is beneficial to finding the tiny focus by the user, thereby improving the accuracy of image diagnosis.
In the following, how the second medical image is displayed in the image display window when the user performs a panning operation or a zooming operation on the first medical image is described.
First, translation operation
The user can perform a panning operation on the first medical image, including two situations:
taking the first medical image as a tomographic image and the second medical image as a positioning image as an example, there is a case where when the tomographic image is displayed in a landscape as shown in fig. 3 and the positioning image is located on the left or right side thereof, the tomographic image can be operated to shift left or right; alternatively, when the tomographic image is displayed in the vertical screen as shown in fig. 4 and the positioning image is located on the upper or lower side thereof, the tomographic image may be operated to be translated up and down.
The above two situations of translation operations may all affect the display position and/or the display size of the positioning image, that is, in the process of translating the tomographic image, the imaging diagnostic software may automatically calculate the position relationship between the positioning image and the tomographic image, and then display the positioning image in a better manner by zooming the positioning image or replacing the display position of the positioning image, which will be described in detail below.
Referring to the schematic flow chart of displaying the second medical image during the translation of the first medical image shown in fig. 6, in this embodiment, the step S202 may specifically include steps S601-S606:
s601: controlling the first medical image to translate in response to a user's translation operation on the first medical image.
In this embodiment, the triggering manner of the translation operation is not limited, for example, the user may slide left and right on the image display window by using a finger to implement left and right translation of the first medical image, may also slide up and down on the image display window by using a finger to implement up and down translation of the first medical image, and of course, may also operate the relevant function key to control translation of the first medical image.
S602: judging whether the translation direction of the first medical image is the same as the direction of the second medical image in the translation process of the first medical image; if the directions are the same, executing S603; if the direction is different, S606 is executed.
Taking the horizontal screen display mode shown in fig. 3 as an example, when the positioning image is located on the left side of the tomographic image, if the user operates the tomographic image to translate leftward, the translation direction of the tomographic image is the same as the direction of the positioning image, and conversely, if the user operates the tomographic image to translate rightward, the translation direction of the tomographic image is different from the direction of the positioning image.
Taking the vertical screen display manner shown in fig. 4 as an example, when the positioning image is located on the upper side of the tomographic image, if the user operates the tomographic image to translate upward, the translation direction of the tomographic image is the same as the direction of the positioning image, otherwise, if the user operates the tomographic image to translate downward, the translation direction of the tomographic image is different from the direction of the positioning image.
And detecting whether the first medical image and the second medical image are overlapped in real time in the process of translating the first medical image to the direction in which the second medical image is positioned.
S603: determining whether an overlap occurs between the first medical image and the second medical image; if so, executing S604; if not, S605 is executed.
S604: changing a display position and/or a display size of the second medical image.
In this embodiment, if the first medical image and the second medical image are overlapped, S604 may specifically include:
step A1: and judging whether the target side length of the second medical image is smaller than a minimum preset side length, wherein the target side length is the side length parallel to the translation direction in the second medical image.
As mentioned above, in order to enable the user to clearly see the second medical image, a minimum display side length may be preset for the second medical image, the minimum display side length is referred to as a minimum preset side length in this step, and when the first medical image and the second medical image overlap, it is detected whether the target side length of the second medical image is smaller than the minimum preset side length.
Step B1: and if the length of the minimum preset side is larger than or equal to the minimum preset side length, reducing the display size of the second medical image to enable the first medical image and the second medical image not to be overlapped.
And if the target side length of the second medical image is larger than or equal to the minimum preset side length, continuously reducing the second medical image to shorten the target side length of the second medical image so as to eliminate the overlapping between the second medical image and the first medical image.
Step C1: and if the length of the side of the second medical image is less than the minimum preset side length, searching a changed area in a display area except the first medical image, and displaying the second medical image in the changed area, wherein the side length parallel to the translation direction in the changed area is greater than or equal to the minimum preset side length.
If the target side length of the second medical image is gradually shortened to be smaller than the minimum preset side length, or the target side length of the second medical image is equal to the minimum preset side length when the first medical image starts to translate, a change area which is not overlapped with the first medical image can be searched for displaying the second medical image.
For example, when the user operates the tomographic image shown in fig. 3 to shift to the left and moves to the position shown in fig. 7, a modification area, such as a lower right corner area of a window, may be searched for on the right side of the tomographic image, and the positioning image may be displayed in the modification area. Optionally, the positioning image at this time may be displayed in a size as large as possible, or may be displayed in any size larger than the minimum preset side length, as long as no image overlap occurs.
S605: the display position and display size of the second medical image are maintained.
If the first medical image and the second medical image do not overlap, the display position and the display size of the second medical image can be kept unchanged.
S606: the display position of the second medical image is maintained, and the display size of the second medical image is maintained or increased.
During the process of translating the first medical image to the opposite direction of the second medical image, the second medical image can adopt any one of the following display modes:
mode 1, keeping the display position and the display size of the second medical image unchanged;
mode 2 is to increase the display size of the second medical image while keeping the display position of the second medical image unchanged.
For example, if the user operates the tomogram shown in fig. 3 to translate to the right, the left area of the tomogram will increase continuously, and if the user operates the tomogram shown in fig. 4 to translate to the lower, the upper area of the tomogram will increase continuously, at this time, the display area of the positioning image may be increased by adopting the method 2, so that the positioning image is more clearly displayed on the screen.
In an embodiment of the present application, the "increasing the display size of the second medical image" in S606 may specifically include:
step A2: and judging whether the target side length of the second medical image is smaller than the maximum preset side length, wherein the target side length is the side length parallel to the translation direction in the second medical image.
In the above, in order to avoid the second medical image occupying the display area of the first medical image, a maximum display side length may be preset for the second medical image, in this step, the maximum display side length is referred to as a maximum preset side length, and it is detected whether the target side length of the second medical image is smaller than the maximum preset side length.
Step B2: and if the length of the second medical image is less than the maximum preset side length, increasing the display size of the second medical image, wherein the increased second medical image is not overlapped with the first medical image.
If the target side length of the second medical image is smaller than the maximum preset side length, the second medical image can be conveniently viewed by a user by continuously enlarging the second medical image under the condition that the second medical image is not overlapped with the first medical image.
Step C2: and if the length of the second medical image is larger than or equal to the maximum preset side length, keeping the display size of the second medical image.
If the target side length of the second medical image is gradually increased to the maximum preset side length, or the target side length of the second medical image is equal to the maximum preset side length when the first medical image starts to translate, at this time, the display size of the second medical image can be kept unchanged.
Second, shrink operation
The user may perform a zoom-out operation on the first medical image, and during the zoom-out process of the first medical image, the image diagnosis software may automatically calculate a positional relationship between the second medical image and the first medical image, and then display the second medical image in a better manner, which will be described in detail below.
Referring to the schematic diagram of the second medical image display flow when the first medical image is reduced shown in fig. 8, in this embodiment, the step S202 may specifically include steps S801 to S804:
s801: controlling the first medical image to be reduced in response to a reduction operation of the first medical image by a user.
In this embodiment, the triggering manner of the zoom-out operation is not limited, for example, the user may perform a zoom-out operation on the image display window by using a finger, and may operate the related function key to control the zoom-out of the first medical image.
S802: judging whether the target side length of the second medical image is smaller than the maximum preset side length or not in the process of reducing the first medical image; if the length of the edge is smaller than the maximum preset edge length, executing S803; if the length is greater than or equal to the maximum preset side length, S804 is executed.
The target side length is a side length parallel to a target direction in the second medical image, and the target direction is an arrangement direction of the second medical image and the first medical image in the image display window.
For example, when the scout image and the tomographic image are placed left and right as shown in fig. 3, the target side length is the lateral length of the scout image; for another example, when the scout image and the tomographic image are placed one above the other as shown in fig. 4, the target side length is the longitudinal length of the scout image.
S803: increasing a display size of the second medical image, wherein the increased second medical image is non-overlapping with the first medical image.
For example, in the process that the tomographic image shown in fig. 3 is gradually reduced, the left area of the tomographic image is enlarged, and when the lateral length of the positioning image is smaller than the maximum preset side length, the display area of the positioning image can be enlarged as much as possible, so that the lateral length is still smaller than the maximum preset side length and the images are not overlapped, thereby presenting the positioning image more clearly; for another example, in the process that the tomographic image is gradually reduced as shown in fig. 4, the upper side area of the tomographic image is enlarged, and when the longitudinal length of the positioning image is smaller than the maximum preset side length, the display area of the positioning image can be enlarged as much as possible, so that the longitudinal length is still smaller than the maximum preset side length and the images are not overlapped, thereby presenting the positioning image more clearly.
S804: the display position and display size of the second medical image are maintained.
For example, in the process of gradually reducing the tomographic image shown in fig. 3, when the lateral length of the positioning image is greater than or equal to the maximum preset side length, both the display position and the display size of the positioning image may be kept unchanged; for another example, in the process of gradually reducing the tomographic image shown in fig. 4, when the longitudinal length of the positioning image is greater than or equal to the maximum preset side length, both the display position and the display size of the positioning image may be kept unchanged.
Third, amplifying operation
The user may perform an enlarging operation on the first medical image, and during the enlarging process of the first medical image, the image diagnosis software may automatically calculate a position relationship between the second medical image and the first medical image, and then display the second medical image in a better manner, which will be described in detail below.
Referring to the schematic diagram of the second medical image display flow when the first medical image is enlarged as shown in fig. 9, in this embodiment, the step S202 may specifically include steps S901 to S904:
s901: controlling the first medical image to be magnified in response to a magnification operation of the first medical image by a user.
In this embodiment, the triggering manner of the zoom-in operation is not limited, for example, the user may perform the zoom-in operation on the image display window by using a finger, and of course, the user may operate the related function key to control the zoom-in of the first medical image.
S902: judging whether the first medical image and the second medical image are overlapped or not in the amplification process of the first medical image; if not, executing S903; if so, S904.
And detecting whether the first medical image and the second medical image are overlapped in real time during the amplification of the first medical image.
S903: the display position and display size of the second medical image are maintained.
If the first medical image and the second medical image do not overlap, the display position and the display size of the second medical image can be kept unchanged.
S904: changing a display position and/or a display size of the second medical image.
In this embodiment, if the first medical image and the second medical image are overlapped, S904 may specifically include:
step A3: judging whether the target side length of the second medical image is smaller than the minimum preset side length or not; the target side length is a side length parallel to a target direction in the second medical image, and the target direction is an arrangement direction of the second medical image and the first medical image in the image display window.
For example, when the scout image and the tomographic image are placed left and right as shown in fig. 3, the target side length is the lateral length of the scout image; for another example, when the scout image and the tomographic image are placed one above the other as shown in fig. 4, the target side length is the longitudinal length of the scout image.
Step B3: if the length of the minimum preset side is larger than or equal to the minimum preset side length, reducing the display size of the second medical image until the first medical image and the second medical image are not overlapped.
For example, in the process of gradually enlarging the tomographic image shown in fig. 3, the left area of the tomographic image becomes smaller, and when the lateral length of the positioning image is greater than or equal to the minimum preset side length, the display area of the positioning image (as shown in fig. 10) can be appropriately reduced so that the lateral length is still greater than or equal to the minimum preset side length and the images do not overlap with each other; for another example, in the process of gradually enlarging the tomographic image shown in fig. 4, the upper area of the tomographic image becomes smaller, and when the vertical length of the positioning image is longer than or equal to the minimum preset side length, the display area of the positioning image can be appropriately reduced so that the vertical length is still longer than or equal to the minimum preset side length and the images do not overlap with each other.
Step C3: if the length of the display area is smaller than the minimum preset side length, searching a change area in a display area except the first medical image; if the change area is searched, displaying the second medical image in the change area, and enabling the target side length of the second medical image to be larger than or equal to the minimum preset side length; and if the change area is not searched, hiding the second medical image.
If the target side length of the second medical image is gradually shortened to be smaller than the minimum preset side length, or the target side length of the second medical image is equal to the minimum preset side length when the first medical image starts to be amplified, a change area which is not overlapped with the first medical image can be searched in other display areas to display the second medical image, wherein when the second medical image is displayed in the change area, the target side length of the second medical image is larger than or equal to the minimum preset side length, otherwise, the second medical image can be hidden, and the second medical image is not displayed any more.
It should be noted that, if the user performs the zoom-in operation on the first medical image first and then performs the zoom-out operation, and after the second medical image is hidden due to the zoom-in operation, if the zoom-out operation is performed so that the image display window has a changed area that meets the display requirement of the second medical image, the second medical image is redisplayed in the changed area.
Further, since the image display window in this embodiment only displays one first medical image, if the user wants to change the image display, that is, to change to another first medical image for display, the image change request needs to be triggered, for example, by using the actual function keys of the mobile device or the virtual function keys displayed on the screen of the mobile device.
Therefore, in an embodiment of the present application, the method may further include: in response to a user-triggered image replacement request, the requested replacement image is taken as the currently requested first medical image, and the step of "displaying the currently requested first medical image and the second medical image corresponding to the first medical image in the image display window" in step S201 is continuously performed. In this embodiment, after the user triggers the image replacement request, another first medical image and a corresponding second medical image are displayed in the image display window in a replacement manner, and at this time, the replaced first medical image may also be subjected to the transformation operation in step S202 by the user, for specific implementation, refer to the related description of step S202, and details are not described herein again.
