Abstract

The invention discloses a verification method and a device for positioning information, and a computer device, relates to the technical field of medical treatment, and can solve the problem of relatively low accuracy when positioning information is verified. The method comprises the following steps: acquiring a positioning picture and a current positioning picture of a target patient; calculatingthe coordinate distance between the same pixel points corresponding to the positioning picture and the current positioning picture, and determining the positioning error of the target patient based onthe coordinate distance; comparing the positioning error with a preset tolerance range to obtain a positioning information verification result of the target patient; and outputting the positioning information verification result. The method and the device are suitable for effectively verifying the positioning information in a radiotherapy plan.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a positioning verification method, device and computer equipment. Background technique [0002] The treatment methods for cancer mainly include surgery, radiotherapy and chemotherapy, among which radiotherapy plays a vital role. According to the 2014 World Cancer Report, according to the stage and type of tumor, generally speaking, about 50%-65% of tumor patients need to receive radiation therapy. Domestic related reports show that inaccurate positioning during radiotherapy will greatly increase the recurrence rate of radiotherapy patients. Due to the many times of radiotherapy, the long cycle, and the many factors involved, it is difficult to guarantee the accuracy of positioning, resulting in under-irradiation or over-irradiation of the tumor, which may have become a significant cause of tumor recurrence and death in radiotherapy patients. [0003] The current comm...
