Abstract
Disclosed are a method and system for automatic scan subject positioning in medical imaging. The method includes the following steps: acquiring scan information of a scan subject to be imaged and determining a scan subject scanning feature; identifying, on the basis of the scan subject scanning feature, a corresponding offset characteristic value from a mapping table between scanning features and offset characteristic values; and adjusting, on the basis of the corresponding offset characteristic value, a target position of the scan subject during automatic scan subject positioning.

A method for automatic scan subject positioning in medical imaging, comprising the following steps:
- acquiring scan information of a scan subject to be imaged and determining a scan subject scanning feature;
- identifying, on the basis of the scan subject scanning feature, a corresponding offset characteristic value from a mapping table between scanning features and offset characteristic values;
- and
- adjusting, on the basis of the corresponding offset characteristic value, a target position of the scan subject during the automatic scan subject positioning.
A medical imaging system, comprising:
- a medical imaging apparatus, configured to perform scanning and imaging on a scan subject;
- a scan subject moving table, configured to support the scan subject and movable in a horizontal direction and a vertical direction, the horizontal direction comprising a transverse direction and a longitudinal direction, wherein the scan subject moving table is moved in the longitudinal direction during the scanning and imaging;
- a 3D depth camera, configured to acquire a body contour of the scan subject;
- an automatic positioning module, configured to perform automatic positioning of the scan subject according to scan information of the scan subject and the acquired body contour;
- and
- a positioning optimization module, configured to perform the following:
- acquiring the scan information and determining a scan subject scanning feature;
- identifying, on the basis of the scan subject scanning feature, a corresponding offset characteristic value from a mapping table between scanning features and offset characteristic values;
- and
- adjusting, on the basis of the corresponding offset characteristic value, a target position of the scan subject in the automatic positioning.
