摘要：
A motion compensation system for tracking and compensating for patient motion during a medical imaging scan comprises an optical marker comprising an optically visible pattern and a mounting portion a first optical detector positioned to digitally image the optically visible pattern along a first line of sight a second optical detector positioned to digitally image the optically visible pattern along a second line of sight a tracking engine configured to determine a pose of the object in six degrees of freedom by analyzing images from the first and second optical detectors and a controller interface configured to generate tracking information based on the pose and to electronically transmit the tracking information to a scanner controller to enable compensation within a medical imaging scanner for object motion.
