Abstract

The invention is suitable for the field of medical image segmentation and provides a method and system for automatically segmenting bones from abdomen image data. The method comprises the steps of automatically extracting a first segmentation result comprising an abdomen aorta or part of an abdomen aorta area in the abdomen image data according to shape features of the abdomen aorta; according to the first segmentation result, modifying data comprising the abdomen aorta or part of the abdomen aorta area in the abdomen image data to obtain abdomen image modified data; automatically selecting at least one seed point of the bones from the abdomen image data; and according to the seed point and the abdomen image modified data, obtaining a second segmentation result of the bones by first threshold connection. Accordingly, bone areas can be segmented from an abdomen image automatically and accurately.

Description

technical field [0001] The invention relates to the field of medical image segmentation, in particular to a method and system for automatically segmenting bones from abdominal image data. Background technique [0002] Image segmentation technology is a technology to extract the target area of ​​interest from the image with the help of computer technology. The practical application of image segmentation includes medical imaging, satellite image positioning objects, intelligent transportation, etc. Medical image segmentation refers to the segmentation of the region of interest or lesion in the medical image. Its purpose is to efficiently determine the clinical morphological features that are crucial to the patient, so as to facilitate the observation and analysis of the morphological features and pathological condition. Existing medical image segmentation uses a basic single image segmentation technology, such as threshold-based segmentation methods, region-based segmentation...
