Embodiment 1

[0033] figure 1 It is a flow chart of the method for delineating the region of interest provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the delineation of the region of interest is quickly performed on the newly added scan image of the patient. The device for delineating the region of interest can be implemented by software and / or hardware, and the device for delineating the region of interest can be configured on a computing device, specifically including the following steps:

[0034] S110. Acquire a newly added scanned image, an original image, and a delineated image of a region of interest in the original image of the target object, wherein the newly added scanned image and the original image are scanned images of the same part of the target object at different periods.

[0035] Exemplarily, the target object may be an object to be image-scanned, such as a human body or an animal. The newly added image may be a newly ...

Embodiment 2

[0048] figure 2 It is a flow chart of the method for delineating a region of interest provided in Embodiment 2 of the present invention. The embodiment of the present invention can be combined with various alternative solutions in the foregoing embodiments. In the embodiment of the present invention, optionally, the training method of the delineation model includes: based on the historical original image in the historical image data of each object, the delineation image of the region of interest on the historical original image and the historical newly added The scanned image is input into the delineation model to be trained, and the delineation prediction image of the region of interest on the newly added scan image in the history is output, wherein the delineation model is used for the historical original image and historical original image of each object. Preprocessing the delineated image of the region of interest and the newly added scanned image in history, and predicti...

Embodiment 3

[0061] image 3 It is a flow chart of the method for delineating a region of interest provided in Embodiment 3 of the present invention. The embodiment of the present invention can be combined with various alternative solutions in the foregoing embodiments. In the embodiment of the present invention, optionally, after obtaining the delineated image of the region of interest on the newly added scanned image of the target object, the method further includes: storing the scanned images of the target object at different periods and The sketched image of the region of interest in the scanned image; based on the position information and change trend of the sketched image of the region of interest in the scanned images of different periods, correcting the sketched image of the region of interest on the newly added scanned image test. Based on the change information of the delineated image of the region of interest on the newly added scanned image and the delineated image of the regi...

Abstract

The embodiment of the invention discloses an area-of-interest sketching method and device, equipment and a storage medium. The method comprises the steps of acquiring a newly-added scanning image andan original image of a target object and a sketching image of a region of interest in the original image, wherein the newly-added scanning image and the original image are scanning images of the samepart of the target object in different periods; inputting the newly added scanning image, the original image and a sketching image of a region of interest in the original image into a trained sketching model; wherein the delineation model is obtained by training based on multiple groups of historical image data in different periods, and obtaining a delineation image of an area-of-interest on the newly added scanning image of the target object. Therefore, the effect of rapidly and accurately delineating the region of interest is achieved.

Description

technical field [0001] Embodiments of the present invention relate to medical imaging technology, and in particular to a method, device, device and storage medium for delineating a region of interest. Background technique [0002] In the general radiotherapy process, if it is necessary to segment the target area and organ-at-risk for the newly added image, the physician generally needs to manually outline it. Organ delineation relies entirely on physicians' manual delineation, which greatly limits the development of adaptive radiotherapy procedures. [0003] A more advanced method is to delineate and map the target area and organs at risk on the original image to the new image through registration (including rigid registration or deformation registration), and perform appropriate post-processing. Even so, the deformed outline usually requires a lot of manual modification by the physician, which takes a long time. Contents of the invention [0004] Embodiments of the pres...
