Abstract

A method for image segmentation includes acquiring a three-dimensional (3D) image that includes a plurality of two-dimensional (2D) images arranged in a spatial order. The method also includes determining a preliminary seed point in a first 2D image of the plurality of 2D images. The method further includes determining, based on the preliminary seed point, a final seed point in a second 2D image of the plurality of 2D images, and determining, based on the final seed point, a volume of interest (VOI) in the 3D image.

Description

technical field [0001] The invention relates to the field of medical images, in particular to a method and device for dividing a volume of interest in a three-dimensional medical image. Background technique [0002] The segmentation of the volume of interest in the 3D medical image can be used to observe and analyze the shape, characteristics, and related pathological conditions of the volume of interest, as well as image reconstruction and fusion. [0003] Generally speaking, there are mainly the following segmentation methods: threshold-based segmentation methods, region-based segmentation methods, edge-based segmentation methods, and some segmentation methods based on specific theories. In the actual segmentation, according to whether manual participation is required, it can also be divided into automatic segmentation method, semi-automatic segmentation method, or segmentation of the volume of interest outlined by the user (doctor, technician). For semi-automatic segment...
