Abstract

The invention discloses a positioning method and system for imaging scanning. The method includes the steps of putting a to-be-scanned object on a patient table; obtaining a 3D image including a target scanning area of the to-be-scanned object through a 3D camera shooting device, wherein the 3D image includes depth information of the to-be-scanned object; obtaining a positioning image including the target scanning area of the to-be-scanned object through a scanning device; determining the target scanning area based on the positioning image; moving the patient table in at least one direction based on the positioning image, the 3D image and the target scanning area. By means of the positioning system, a user does not need to position a patient manually before scanning, positioning can be directly and automatically conducted after scanning of a positioning piece is completed, scanning efficiency is improved, and the positioning accuracy can be improved by means of a 3D field depth camerashooting technology.

Description

technical field [0001] The present invention relates to the field of medical imaging equipment, in particular to a positioning method and system for imaging and scanning. Background technique [0002] According to the image reconstruction principle of computerized tomography (CT), the best image quality can be achieved when the target scanning area of ​​the scanned object or human body is placed at the rotation center (ie virtual isocenter) of the scanning device. In the prior art, the operator positions through the laser positioning lights on the scanning system, which is particularly inconvenient for vertical positioning. The positioning method using laser positioning lights is less accurate and time-consuming, and it is easy to cause the object under test or the human body to be scanned too off-centre, thereby producing artifacts in the reconstructed image. Contents of the invention [0003] In order to solve the problems of inconvenient positioning in the vertical dir...
