1. A method of creating representative position information of a patient during a medical imaging scan, the method comprising:
prior to performing the medical imaging scan, performing an initial LiDAR data acquisition to obtain baseline LiDAR data;
performing segmentation of the baseline LiDAR data, wherein the baseline LiDAR data includes a three-dimensional (3D) point cloud model;
performing continuous LiDAR data acquisition to obtain continuous LiDAR data, which includes a real-time 3D point cloud model; and
comparing the continuous LiDAR data with the baseline LiDAR data to detect motion of the patient.
