Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic diagram of a pathological image display method according to an embodiment of the present application. The method is applied to a pathological image display device. The method comprises the following steps:
101: the pathological image display device acquires at least one image data of a pathological image, and caches the at least one image data to a preset storage space, wherein the at least one image data corresponds to the at least one resolution level one by one.
For example, the user may input basic information of the pathology image in the information input field of the pathology image display apparatus, for example, the basic information may be a name, a number, an identification, etc. of the pathology image; then, the pathology image display apparatus reads at least one image data corresponding to the at least one resolution LeveL from the medical data block according to the basic information of the pathology image, wherein the at least one resolution LeveL may be LeveL0 to LeveL9.
The medical data block can be an openhide medical data block, and the openhide supports reading of image data of pathological images in various formats, so that the pathological images in various formats can be read and displayed on a display window. Accordingly, the pathology image display apparatus may read at least one image data of the pathology image at least one resolution level through the open source interface of the openhide. The at least one image data may be read from the openhide by a memory file mapping technique, for example.
The preset storage space is a storage space for caching the pathological image, and may be a temporary entity space or a virtual storage space, which is not limited in this application.
In one embodiment of the present application, the preset storage space is a 3D storage space, and thus, the at least one image data may be stored to a 3D memory in the 3D storage space. As shown in fig. 2, the 3D memory has a plurality of active layers, and the at least one image data may be stored to a different active layer. For example, each image data may be assigned with an active layer index information indicating the location information of an active layer in which the image data is stored, and different image data may be stored to different active layers according to the active layer index information. For example, before the active layer index information is allocated for each image data, a remaining storage space of each active layer may be determined, and then the at least one image data may be allocated with the active layer index information according to the size of the remaining storage space, e.g., an active layer having a larger remaining space may be allocated to image data having a larger resolution.
Further, each active layer may be provided with a plurality of memories, and thus, in assigning active layer index information to each image data, corresponding memory index information indicating a position of a memory storing the image data in the active layer may also be assigned to each image data.
Therefore, the image display apparatus can store each image data to the corresponding memory, i.e., the preset storage space, in accordance with the allocated active layer index information and memory index information for each image data.
102: the pathological image display device acquires a first resolution level input by a user, acquires a first image data block corresponding to the first resolution level from the storage space according to the first resolution level and the size of a display window, and displays a first sub-image corresponding to the first image data block on the display window, wherein the first resolution level is any one of the at least one resolution level.
Illustratively, the pathological image display device determines a storage path of the image data corresponding to the first resolution level in the storage space, for example, active layer index information and memory index information of the image data; and then, according to the storage path, the size of the display window and the preset area, obtaining a first index value of the first image data block, wherein the first index value comprises a first pixel coordinate, a length and a width of the first image data block, and the first pixel coordinate is a pixel coordinate of a pixel point at the leftmost upper corner in the first image data block. Specifically, since the display window cannot display all the pathology at one time, a default display area may be set, and the default display area is a partial area in which a pathology image is displayed by default when a user views one pathology image and is displayed for the first time. By way of example, the preset area may be a central area, an upper left corner area, etc. of the pathology image; and finally, reading a first image data block corresponding to the first resolution level from the storage space according to the storage path and the first index value, namely cascading the index information of the storage path with the first index value to obtain a first target index value, and reading the first image data block from the preset space according to the target index value. And rendering the first image data block, and displaying the rendered first sub-image in a display window.
For example, if the default display area is set as the center area, as shown in fig. 3, the first index value ((x, y), L, W) is determined, and then the first index value and the index information of the storage path are concatenated to obtain a first target index value (Layer) id ，ceLL id (x, y), L, W), wherein Layer id Representing the active layer index, ceLL id Representing the memory index, (x, y) representing the first pixel coordinates, L representing the length of the first image data block, W representing the width; then, according to the first target index value, reading a first image data block corresponding to the first resolution level from the corresponding active layer and the memory; finally, the first image data block is processedAnd rendering rows, and displaying the first sub-image in the display window.
103: and the pathological image display device acquires a second image data block corresponding to the first resolution level from the storage space according to the operation of the user, and displays a second sub-image corresponding to the second image data block in the display window, wherein the first sub-image and the second sub-image are different sub-areas in the pathological image.
Illustratively, the user operation includes a drag operation, a click operation, a move instruction (e.g., an instruction generated by clicking an up, down, left, right key of a keyboard or virtual keyboard), and so forth. For example, since the display window displays a partial region of the pathology image, when the user wants to see other regions of the pathology image, the pathology image may be dragged by a mouse or directly clicked by a mouse.
For example, in the case that the user operation is a drag operation, determining a drag trajectory of the pathology image according to the drag operation; determining a second index value according to the dragging track and the first index value, namely determining the number of pixel points dragged by the user and the dragging direction according to the dragging track, for example, if the user drags four pixel points leftwards, the second index value is ((x-4, y), L, W); and acquiring a second image data block corresponding to the second index value from the storage space according to the second index value and the storage path, rendering the second image data block, and displaying a rendering result (namely a second sub-image) on the display window, wherein the second index value comprises a second pixel coordinate, a length and a width, the second pixel coordinate is a pixel coordinate of a pixel point at the leftmost upper corner in the second image data block, and the length and the width are respectively the length and the width of the second image data block.
For example, in the case where the user operation is a movement instruction, the movement direction and the movement distance of the pathology image are determined according to the movement instruction, that is, according to the mapping relationship among the movement instruction, the movement direction, and the movement distance. For example, a movement instruction generated by clicking the key "∈r once is used for indicating to move 4 pixels upwards; determining the second index value according to the moving direction, the moving distance and the first index value; and acquiring a second image data block corresponding to the second index value from the storage space according to the second index value and the storage path.
Likewise, a second image data block is obtained from the storage space according to the second index value, namely the second index value and the storage path are cascaded to obtain a second target index value; then, the second image data block is read from the storage space according to the second target index value.
It should be understood that, in practical applications, the user may move the pathology image by other ways to view other areas of the pathology image, and the moving way is not limited in this application.
The second image data is subjected to coordinate transformation according to the second pixel coordinates of the second image data, so that the second image is transformed to the center of the display window, and the second sub-image corresponding to the second image data block is displayed centrally, so that no matter which area of the pathological image is watched, the area can be displayed centrally, and the viewing experience of a user is improved. Specifically, a third pixel coordinate of the second image data block, namely a pixel coordinate of a central pixel point of the second image data block, is obtained; then, determining a transformation matrix according to the third pixel coordinate and the center coordinate of the display window; and according to the transformation matrix, performing pixel coordinate transformation on the second image data block, rendering the second image data block subjected to the pixel coordinate transformation, and displaying a second sub-image corresponding to the second image data block in the display window.
It will be appreciated that the second image data block may be subjected to a coordinate transformation prior to rendering the second image data block, such that the rendered second sub-image may be displayed directly or may be rendered first, and then subjected to a pixel coordinate transformation prior to rendering the second sub-image to transform the second sub-image to a centered display. The sequence of the pixel coordinate transformation is not limited in this application.
It can be seen that, although only a partial area of the pathological image is displayed in the display window at each time, the user can freely drag the pathological image to watch any area in the pathological image, and because the image data of the pathological image is cached in the storage space in advance before the pathological image is displayed, the time for loading a new area is relatively short in the process of dragging the pathological image by the user, the user can watch a complete image visually, so that no matter how large the resolution of the pathological image is, the pathological image can be completely displayed, the user can watch the complete pathological image without being limited by the resolution, and the experience of the user for looking up the pathological image is improved.
In one embodiment of the present application, the display window includes an labeling area, and in a case that the user clicks on the labeling area, the pathological image display device may acquire a region to be labeled in the pathological image; acquiring a fourth image data block corresponding to the region to be marked from the storage space, wherein the mode of acquiring the fourth image data block is similar to the mode of acquiring the first image data block and is not described; and then rendering the fourth image data block, and displaying the region to be annotated in the display window.
For example, the user may input annotation data in the annotation region and flash display the annotation data input by the user in the annotation region, thereby facilitating the annotation by the user.
In one embodiment of the application, in order to more conveniently locate a certain area in the pathological image, a thumbnail of the pathological image can be set in the display window, a user can click on a corresponding area in the thumbnail, then the area can be quickly located, and the image of the area is displayed in the display window, so that the labeling personnel can conveniently and quickly locate, review and label, and the like.
In one embodiment of the present application, since only one image area in the pathology image is displayed at a time, there is no overall visual effect, and it may not be possible for the user to determine explicitly which areas need to be marked. Therefore, the pathological image can be compared with the marked pathological image, and the area to be marked in the pathological image can be determined. Under the condition that the image displayed by the labeling window comprises the region to be labeled, the region to be labeled is highlighted to prompt the highlighted region to be the region to be labeled, so that a user can label the highlighted region conveniently, wherein the highlighting can be displayed in a box outlining or coloring mode, and the highlighting mode is not limited.
In one embodiment of the present application, the resolution of the pathology image is switched during the process of switching the resolution of the pathology image, for example, when the currently displayed image is reduced or enlarged, i.e., the resolution of the pathology image is switched. The present application describes reduction of an image and resolution as an example. Specifically, in the process of switching from the first resolution level to the second resolution level, the second sub-image can be transformed by a bilinear interpolation algorithm to obtain a third sub-image, and the third sub-image is displayed in the display window, wherein the respective resolution level of the third sub-image is the second resolution level; then, a third image data block corresponding to the second resolution level is acquired from the preset storage space, wherein a manner of acquiring the third image data block is similar to that of acquiring the first image data block, and is not described. And rendering the third image data block to obtain a fourth sub-image, and displaying the fourth sub-image in the display window, namely replacing the third sub-image with the fourth sub-image for display.
It can be seen that when the resolution is switched, for example, when the currently displayed image is reduced, the conventional image scaling technology is used for smoothing and transition, for example, an interpolation algorithm can be used for displaying the reduced image, when it is determined that the reduction multiple can reduce the current resolution to the next low resolution, image data corresponding to the low resolution is acquired from the storage space, then the image data is rendered, and an image with the low resolution is displayed, so that in the process of switching the resolution, the transition is performed by adopting the interpolation algorithm, and in the process of switching the resolution, the image which is excessively displayed can be displayed first, and thus the phenomenon of image display blocking caused by switching the resolution is avoided.
In some possible embodiments, the pathological image display method of the present application may be applied to the field of smart medical treatment. For example, the pathological image of the patient can be displayed through the pathological image display method, so that doctors can watch the pathological image under each resolution, and accordingly, corresponding diagnosis and treatment schemes can be better formulated for the patient, and further progress of medical science and technology is promoted.
