Acquistion of 3D information with dedicated cameras is becoming more popular in healthcare applications for motion and position registration as well as for diagnostic purposes. We present the technical feasibility of such a camera system in a MRI environment. Respiratory movement was acquired by the camera during free-breathing abdominal MRI acquistions. The acquired images were corrected retrospectively with the respiratory belt information, the depth information and intensity amplitude of the camera. The comparison with pneumatic belt data shows strong correlation and motion artifacts were greatly reduced with the camera data.
