摘要： The disclosure herein provides methods, systems, and devices for tracking motion of a patient or object of interest during biomedical imaging and for compensating for that motion in the biomedical imaging scanner and/or the resulting images to reduce or eliminate motion artifacts. In an embodiment, a motion tracking system is configured to overlay tracking data over biomedical imaging data in order to display the tracking data along with its associated image data. In an embodiment, a motion tracking system is configured to overlay tracking data over biomedical imaging data in order to display the tracking data along with its associated image data. In an embodiment, one or more detectors are configured to detect images of a patient, and a detector processing interface is configured to analyze the images to estimate motion or movement of the patient and to generate tracking data describing the patient's motion. The detector processing interface is configured to send the tracking data to a scanner controller to enable adjustment of scanning parameters in real-time in response to the patient's motion.

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.
