显示医学图像

Resumen de: WO2025181004A1

Proposed are schemes, solutions, concepts, designs, methods and systems pertaining to displaying a medical image of a subject. Specifically, a segmented anatomical plane image of a 3D medical image of the subject is displayed. Typically, after a user has selected a target/desired anatomical plane to be displayed for observation, the location of the anatomical plane in the 3D medical image is identified by segmenting the 3D medical image to establish anatomical context. Then, the segmented 3D medical image is processed to generate an anatomical plane image. In contrast, the invention provides that the step of segmenting the 3D medical image begins before the user selects/requests the target anatomical plane. Thus, when the user selects the target anatomical plane, the 3D medical image may already be segmented (or may already be in the process of being segmented), reducing the length of time between the request and the presentation of the anatomical plane image.
