Method and device for locating a lesion

Abstract

The present application provides a method and device for locating a lesion, which detects the position parameters of the spine from the medical image, and determines the intersection of the extension line of the spine and the edge of the trunk in the medical image. The line connecting the center point and the intersection point is used as the dividing line between the left area and the right area of ​​the medical image, and the dividing line of the torso in the front and rear directions in the medical image is determined according to the target vertical line of the line connecting the center point and the intersection point. According to the demarcation line, determine the area where the lesion is located. Based on the physiological structure characteristics of the spine, determine the intersection point of the extension line of the spine and the edge of the trunk, and further determine the connection line between the center point and the intersection point of the area occupied by the spine and the vertical line of the connection line, so as to determine the dividing line of different regions. The demarcation line is the purpose of determining the area where the lesion is located. Because the physiological structure of the spine is relatively stable, it has higher accuracy compared with manual labeling, and because it is automatically realized, it has higher accuracy than manual labeling high efficiency.

Description

technical field [0001] The present application relates to the technical field of medical diagnosis, in particular to a method and device for locating a lesion. Background technique [0002] At present, some algorithms based on deep learning have been able to determine the coordinates of lesions in medical images such as CT images. [0003] However, in addition to the coordinate position, the relative position of the lesion to the trunk, that is, which area of ​​the trunk the lesion is located in (for example, the area includes the front, back, left, and right), is also of great significance for the diagnosis of the disease and the choice of treatment methods. In the prior art, the relative position of the lesion and the torso is usually determined by manually marking or by means of additional markers. [0004] However, the efficiency and accuracy of manual labeling are not high. With the help of additional markers, it is necessary to fix the ward near the markers when taki...

[0004] However, the efficiency and accuracy of manual labeling are not high

With the help of additional markers, it is necessary to fix the ward near the markers when taking medical images, but some patients cannot achieve this special position fixation due to trauma and other reasons, so the use of additional markers is applicable limited sex
