Abstract
A method for positioning a target in a three-dimensional CT image and a security check system. The method includes: displaying a three-dimensional CT image; receiving a selection by a user of at least one area of the three-dimensional CT image at a first viewing angle to generate a first three-dimensional description; receiving a selection by the user of at least one area of the three-dimensional CT image at a second viewing angle to generate a second three-dimensional description, wherein 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 a size, a location, and/or 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.
