Abstract
A motion tracker including a head band and laser devices that direct laser beams having non-concentric axes to a charge coupled device is used to determine movement of a patient during a CT scan. When the patient is motionless, the laser devices each direct a laser beam along a line, and the laser beams contact the charge coupled device at a contact location. If the patient moves, the laser devices, and therefore the contact locations, move. The charge coupled device detects the movement of the contact locations to determine the movement of the patient. A computer adjusts the x-ray image taken at the time of the movement to accommodate for this movement.
