Abstract
The present disclosure relates to systems and methods for determining a motion of an object during imaging. The systems and methods may cause a light emission device to project a structured light onto the object, and cause a light reception device to detect light resulting from the structured light as projected onto the object and generate a plurality of measured images of the structured light based on the detected light. The systems and methods may further determine the motion of the object based on the plurality of measured images of the structured light and a reference image of the structured light.
Claims17
A system, comprising:
- a scanning device configured to acquire scanning data of an object by scanning the object;
- a coil component;
