Abstract

The invention provides a method for intelligent staging of gastric cancer based on CT images; the method includes the following steps: including the following steps: converting acquired CT medical files into CT images; the CT images at least include stomach CT images; The CT image is preprocessed to obtain a preprocessed CT image; the stomach wall is separated from the preprocessed CT image to obtain a mask image corresponding to the stomach wall; the mask image is processed to extract the The stomach wall and the center line of the stomach wall; the stomach wall is segmented based on the center line, and the local tissue area generated by the segmentation and the pixel value distribution of the local tissue area are obtained; The functions of separation and extraction can realize autonomous analysis of gastric cancer-related medical images without excessive participation of doctors, thus greatly reducing the workload of doctors and improving the efficiency of doctors' diagnosis of diseases.

Description

technical field [0001] The invention relates to the field of physics, in particular to a medical image analysis technology, in particular to an intelligent staging method for gastric cancer based on CT images. Background technique [0002] The high morbidity and mortality of gastric cancer has seriously affected human health worldwide, and has always been highly valued by patients, medical experts and researchers. [0003] Computed tomography (CT) can help determine the location and extent of gastric cancer, provide a basis for the diagnosis and staging of the disease, and guide the selection of surgical methods. However, the number of complete upper abdominal CT images of a patient with gastric cancer ranges from dozens of It can range from hundreds to hundreds. In the face of massive data, doctors have limited energy and physical strength, which greatly increases the workload of doctors, and at the same time reduces the efficiency of doctors in diagnosing diseases. [000...
