Abstract :
The importance of motion correction in 3D medical imaging increases with increasing scanner resolution. It is necessary for scanners with long image acquisition and low contrast images to correct for patient motion in order to optimize image quality. We present a near infrared structured light stereo depth map system for head motion estimation inside 3D medical scanners with limited space.
