[0002] When displaying all images in a DICOM image sequence, a solution is used to preserve the image display state after page turning and synchronization. Because the cornerstone.js library processes image display based on panes, not images, the pane information of the previous image is directly applied to the next image after page turning, resulting in images turning white or black.

[0069] Next, a sequence synchronization processing method based on DICOM images in this exemplary embodiment will be further described.

[0070] As described in step S110 , a captured image is obtained from a preset image database.

[0071] In one embodiment of the present invention, the specific process of "obtaining the captured image from the preset image database" in step S110 may be further explained in conjunction with the following description.

[0072] As described in the following steps,

[0073] S210, determining a DICOM image in the preset image database;

[0074] S220, determining visible area information according to the DICOM image;

[0075] S230: Determine a target image in the visible area information that is inconsistent with the preset visible area information, and mark the target image as a captured image.

[0076] It should be noted that the web side is based on cornerstone.js, vue front-end framework and pinia repository and displays DICOM images.

[0077] As an example, sequence synchronization is enabled to perform synchronization operations such as moving, rotating, scaling, and adjusting windows on images with inconsistent basic viewport information.

[0078] As described in step S230, a target image that is inconsistent with the preset visible area information is determined within the visible area information, and the target image is marked as a captured image.

[0079] In one embodiment of the present invention, the specific process of "determining a target image that is inconsistent with the preset visible area information within the visible area information and marking the target image as a captured image" in step S230 can be further explained in combination with the following description.

[0080] As described in the following steps,

[0081] S310: Determine target position information of the visible area information within the visible pane;

[0082] S320: Determine whether there are any adjustment attributes based on the target position information, wherein the adjustment attributes include at least scaling, rotation, translation, and window width and window position;

[0083] S330: When the preset visible area information does not contain the adjustment attribute corresponding to the visible area information, determining a target image whose visible area information is inconsistent with the preset visible area information.

[0084] As an example, when acquiring images, the data of the basic viewport image may be different due to differences in acquisition equipment or acquisition of different parts of the body. Doctors need to view images from different directions, sizes, or contrasts to determine the patient's condition information, and need to rotate, move, scale, and adjust the window width and window position of the image. In the case of sequence synchronization or full image synchronization, it is necessary to ensure that the doctor's operations on the image can be displayed normally on the screen.

[0085] As described in step S130, when in the sequence synchronization state, storage synchronization object data is constructed based on the acquired image, wherein the data type of the storage synchronization object data includes complete image visible area data and incremental visible area data.

[0086] In one embodiment of the present invention, the specific process of step S130 "when in the sequence synchronization state, constructing and storing synchronization object data based on the acquired image, wherein the data type of the stored synchronization object data includes complete image visible area data and incremental visible area data" can be further explained in combination with the following description.

[0087] As described in the following steps,

[0088] S410, determining an identifier corresponding to the collected image according to the collected image;

[0089] S420, generating a sequence identifier according to the identifier;

[0090] S430, generating and storing synchronization object data according to the identifier, the sequence identifier, the first image ID corresponding to the acquired image, the first synchronization operation difference corresponding to the acquired image, and the complete image visible area data; and / or,

[0091] S440: Generate storage synchronization object data according to the identifier, the sequence identifier, the second synchronization operation difference corresponding to the acquired image, and the incremental visible area data.

[0092] It should be noted that the pinia repository is used to record the incremental or decrement data generated by each synchronization operation, and the synchronization object data is established and stored with the image check identifier, the sequence identifier as the key, and the synchronization operation difference as the value.

[0093] As an example, two types of data are created: 1. complete image viewport data, and 2. incremental viewport data.

[0094] As described in step S430, storage synchronization object data is generated according to the identifier, the sequence identifier, the first image ID corresponding to the acquired image, the first synchronization operation difference corresponding to the acquired image, and the complete image visible area data.

[0095] In one embodiment of the present invention, the specific process of "generating and storing synchronization object data based on the identifier, the sequence identifier, the first image ID corresponding to the acquired image, the first synchronization operation difference corresponding to the acquired image and the complete image visible area data" described in step S430 can be further explained in combination with the following description.

[0096] As described in the following steps,

[0097] S510, generating first current operation information according to a first image ID and image recording information corresponding to the first image ID;

[0098] S520: Determine whether the first current operation information is in a first synchronization state, where the first synchronization state includes synchronization disabled, sequence synchronization, and full synchronization;

[0099] S530: When the first synchronization state is in the synchronization disabled state, determining whether a first image ID corresponding to the current operation information exists in the complete image visible area data; if so, modifying the complete image visible area data and marking it as a first synchronization operation difference; or

[0100] S540: When the first synchronization state is in the sequence synchronization, modify the complete image visible area data according to the sequence identifier corresponding to the first image ID and mark it as a first synchronization operation difference; or

[0101] S550: When the first synchronization state is in the full synchronization, modify the data of the complete image visible area and mark it as a first synchronization operation difference;

[0102] S560: Generate and store synchronization object data according to the identifier, the sequence identifier, the first image ID, the first synchronization operation difference, and the complete image visible area data.

[0103] It should be noted that the complete image visible area data is saved with the final key composed of the examination identifier, sequence identifier, and image ID, and the image viewport as the value to build a storage synchronization object; the image is recorded when it is first displayed on the screen, and each subsequent operation of the doctor on the image is recorded.

[0104] In a specific implementation, if the synchronization function is not enabled, it will check whether the image ID of the current operation exists in the complete image visible area data. If so, the complete image visible area data will be modified according to the type of operation.

[0105] In a specific implementation, if sequence synchronization is enabled, the complete image visible area data is searched according to the sequence identifier of the current image, and the complete image visible area data of all images in the same sequence are modified accordingly.

[0106] In a specific implementation, if all synchronization is enabled, corresponding changes are made to all complete image visible area data.

[0107] As described in step S440, storage synchronization object data is generated according to the identifier, the sequence identifier, the second synchronization operation difference corresponding to the acquired image, and the incremental visible area data.

[0108] In one embodiment of the present invention, the specific process of "generating and storing synchronization object data according to the identifier, the sequence identifier, the second synchronization operation difference corresponding to the acquired image and the incremental visible area data" in step S440 can be further explained in combination with the following description.

[0109] As described in the following steps,

[0110] S610, generating second current operation information according to the identifier and the sequence identifier;

[0111] S620: Determine whether the second current operation information is in a second synchronization state, where the second synchronization state includes sequence synchronization or full synchronization;

[0112] S630: When the second synchronization state is in the sequence synchronization or the full synchronization, determining whether updated data is found in the incremental visible area data by using a sequence identifier;

[0113] S640: If updated data is found, the incremental visible area data is updated and marked as a second synchronization operation difference; or if updated data is not found, new data is created in the incremental visible area data and marked as a second synchronization operation difference;

[0114] S650: Generate storage synchronization object data according to the identifier, the sequence identifier, the second synchronization operation difference, and the incremental visible area data.

[0115] It should be noted that the incremental visible area data object uses the check identifier concatenated with the sequence identifier as the key and the incremental data as the value to construct the storage synchronization object data.

[0116] As an example, movement records the difference between the x-axis and y-axis based on the default movement amount; scaling records the ratio of the current scaling to the default scaling; rotation records the difference based on the default rotation amount; and window width and window position records the difference based on the default window width and window position.

[0117] In a specific implementation, when sequence synchronization or full synchronization is turned on, after each doctor's operation, the data is searched for according to the current image sequence identifier in the incremental visible area data according to the synchronization situation. If the data can be found, the data is updated according to the corresponding operation type. If the data is not found, a new data is created.

[0118] As described in step S140 , target data corresponding to the preset target image is determined based on the complete image visible area data, the incremental visible area data, and the preset target image.

[0119] In one embodiment of the present invention, the specific process of "determining target data corresponding to the preset target image based on the complete image visible area data, the incremental visible area data and the preset target image" in step S140 can be further explained in combination with the following description.

[0120] As described in the following steps,

[0121] S710, obtaining the current image ID of the preset target image;

[0122] S720, searching for data in the complete image visible area data according to the current image ID;

[0123] S730: When no data is found in the complete image visible area data, searching for the data in the incremental visible area data according to the current image sequence identifier corresponding to the current image ID;

[0124] S740: Generate target data according to the search data and default data corresponding to the preset target image.

[0125] It should be noted that when turning the page of the sequence, the image page turning conrnerstorenewimage event is listened to based on the cornerstone.js library, and the current check identifier and sequence identifier are matched in the stored synchronization object data, and the incremental and decrement values are processed to obtain the image data after the synchronization operation. Finally, the incremental or decrement data can be applied based on the default data.

[0126] In one specific implementation, after turning a page, the complete image's visible area data is first searched based on the current image ID. If data is found, it is directly applied to the current image. If the corresponding complete image's visible area data cannot be found, data is searched from the incremental visible area data based on the current image sequence identifier. If data is found, the data is adjusted based on the current image's default data to obtain the latest viewport and then applied. Specific application methods include: if the searched data contains movement information, incremental or decremental adjustment is performed based on the default movement data; if rotation is required, incremental or decremental adjustment is performed based on the default data; if scaling is required, the default scaling value is multiplied by the scaling ratio to obtain the new scaling value; if the window width and window position are required, incremental or decremental adjustment is performed based on the default values; and the latest viewport is obtained by combining the above and applied to the current image. If incremental viewport data cannot be found, the default viewport data is directly used.

[0127] Example 1

[0128] In the same sequence, when performing synchronization operations on data with different window widths, window positions, movement, rotation, and scaling, subsequent image information is correctly displayed when turning pages, and the synchronization operation image status is retained.

[0129] As for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
