SYSTEMS, DEVICES, AND METHODS FOR DETECTING FALSE MOVEMENTS FOR MOTION CORRECTION DURING A MEDICAL IMAGING SCAN

摘要

The systems, methods, and devices described herein generally relate to achieving accurate and robust motion correction by detecting and accounting for false movements in motion correction systems used in conjunction with medical imaging and/or therapeutic systems. In other words, in some embodiments of the systems, methods, and devices described herein can be configured to detect false movements for motion correction during a medical imaging scan and/or therapeutic procedure, and thereby ensure that such false movements are not accounted for in the motion correction process. Upon detection of false movements, the imaging or therapeutic system can be configured to transiently suppress and/or subsequently repeat acquisitions.

1. A computer-implemented method for determining false motion tracked by a motion correction system during a medical imaging scan, the method comprising:
obtaining tracking data, wherein the tracking data reflects motion of a subject of the medical imaging scan or a portion thereof; determining by a false motion discriminator a likelihood of the obtained tracking data reflecting false motion, wherein the false motion is not reflective of true motion of the subject of the medical imaging scan or the portion thereof; and generating by the false motion discriminator a confidence level of the determined likelihood of the obtained tracking data reflecting false motion, wherein the motion correction system is configured to adjust output based on the confidence level, wherein the false motion discriminator comprises a computer processor and an electronic storage medium.
