Patent ID: 11357462

Abstract:
The present invention relates to a 3D perspective indicator and a generation method therefor and an application thereof. The present invention specifically provides a 3D perspective indicator for a CT system and a generation method therefor as well as a method and an apparatus for controlling a scanning range in a CT system. The method for generating a 3D perspective indicator comprises: generating an upper boundary plane and a lower boundary plane perpendicular to a scanning direction and an auxiliary plane perpendicular to the upper boundary plane and the lower boundary plane in a coordinate system space of the CT system, the auxiliary plane being located above a to-be-scanned part of a patient; and identifying an upper contour line intersecting the upper boundary plane and a lower contour line intersecting the lower boundary plane in a point cloud generated based on a depth image of the patient, wherein the 3D perspective indicator comprises the upper contour line and the lower contour line, the upper boundary plane and the lower boundary plane, and the auxiliary plane. The present invention further provides a CT system using the apparatus and a computer-readable storage medium capable of implementing the method.
