METHOD FOR POSITIONING TARGET IN THREE-DIMENSIONAL CT IMAGE AND SECURITY CHECK SYSTEM

摘要

A method for positioning a target in a three-dimensional CT image and a security check system. The method comprises: displaying a three-dimensional CT image; receiving selection by a user of at least one area of the three-dimensional CT image at a first viewing angle, and generating a first three-dimensional description; receiving selection by the user of at least one area of the three-dimensional CT image at a second viewing angle, and generating a second three-dimensional description, where an angle between the first viewing angle and the second viewing angle is within a predetermined range and the first three-dimensional description and the second three-dimensional description are related to at least one of a size, a location, and a physical property of a target at corresponding viewing angles; and determining the target in the three-dimensional CT image based on the first three-dimensional description and the second three-dimensional description. By means of the foregoing solution, a user can conveniently and rapidly mark a suspect object in a CT image.
