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.
