Abstract
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.
