For motion correction using an optical tracking camera, movements must be converted from the camera reference frame to the MR reference frame. This calibration transform is determined by matching poses recorded in both reference frames. We investigated the impact that errors in one or more of these poses has on the resulting calibration. We then investigated the impact that errors in calibration has upon the apparent motion recorded. Thus we outline the necessary precision in the calibration poses to achieve motion correction of different precisions.
