Problems solved by technology

However, the diagnosis based on endoscopic ultrasound images is greatly affected by the doctor's experience and subjective factors, and the diagnostic accuracy of different doctors will be different; some subtle changes in the image are difficult to detect with the naked eye; and the use of EUS-guided fine needle aspiration Cytological examination by EUS guided-finenee-dle aspiration (EUS-FNA) is somewhat invasive

Abstract

The invention relates to a computer-aided method for distinguishing the ultrasound endoscope image of pancreatic cancer, providing a method for extracting and classifying the textural features of the ultrasound endoscope image of pancreatic cancer. The computer-aided method can be used for the computer-aided analysis of the ultrasound endoscope image of pancreatic cancer. 9 general classes which totally comprise 69 textural features are extracted from the ultrasound endoscope image of pancreatic cancer by a digital image processing algorithm. Class spacing is adopted to serve as a separability criterion to preliminarily screen the features; then, a chronological progress search algorithm is used for further screening the features; and the features are classified by a support vector machine. The method is realized by extracting the textural features of the ultrasound endoscope image via the classifier, various objective quantized diagnostic indexes and a method for correctly describing and explaining the ultrasound endoscope image are built, and the accuracy on the ultrasound endoscope early diagnosis of the pancreatic cancer is improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a computer-aided method for discriminating ultrasonic endoscopic images of pancreatic cancer. Background technique [0002] Pancreatic cancer is one of the top ten malignant tumors announced by the World Health Organization, and it is a major disease that seriously endangers human health. In recent years, the incidence of pancreatic cancer has been increasing year by year. Pancreatic cancer develops rapidly and is dangerous, and its clinical features are short course of disease, rapid progression, and high mortality. [0003] The pancreas is a retroperitoneal organ with a hidden location, complex adjacency, and many important organs and blood vessels around it. Therefore, the early detection and early diagnosis of pancreatic cancer have long been a difficult problem in the medical field. [0004] Endoscopic uhrasonography (EUS) has been widely used all over the wor...
