RT Journal Article SR Electronic T1 Accuracy of coregistration of single-photon emission CT with MR via a brain surface matching technique. JF American Journal of Neuroradiology JO Am. J.

This mismatch averaged 4.3 mm as measured by the fiduciary markers and 2.1 mm as measured by the root mean square distance.
