Abstract

The embodiment of the invention discloses a skeleton region determination method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a sequence of original scanning image frames obtained by carrying out the continuous scanning of a target region, wherein the target region comprises a first skeleton and a second skeleton; for each original scanning image frame, determining a segmentation boundary of the first skeleton and the second skeleton according to a preset condition, wherein the preset condition comprises a first preset condition or a second preset condition, the first preset condition is a preset condition corresponding to the foreground region area change of the original scanning image frame, and the second preset condition is a preset condition corresponding to the boundary mask; and for each segmentation boundary, determining a first skeleton region according to the segmentation boundary and the original scanning image frame corresponding to the segmentation boundary. Through the technical scheme of the embodiment of the invention, the technical effect of accurately and quickly dividing different skeleton regions to construct the skeleton model is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical technology, and in particular, to a method, device, electronic device, and storage medium for determining a bone region. Background technique [0002] At present, most of the three-dimensional segmentation methods of CT (Computed Tomography) images for bone regions can be manually positioned or segmented in each CT sequence image, but this method is time-consuming, laborious and inefficient. . [0003] Skeletal region segmentation can also be performed using traditional medical image segmentation methods, mainly including threshold-based feature segmentation. Threshold segmentation is the most common segmentation method for directly detecting target regions, and threshold segmentation can be divided into single-threshold segmentation and multi-threshold segmentation. The effect of threshold segmentation depends on the selection of the threshold, and the threshold segmentation is fast...
