We investigated two new techniques in which the we use external features of the head in subject-to-atlas registration, avoiding the acquisition of MR images per subject. The first method involves placing landmarks on a subject's head exterior and performing affine registration, and the second uses a non-linear fluid registration technique (LDDMM) on the external head-shape of a subject.
