A non-rigid image registration method for co-registering high-resolution PET data and MR images of the hand is described and evaluated. Employing this protocol to register synthetic data indicated a the mean registration error of less than approximately 1.5 mm. Measurements made in images acquired from patients with osteoarthritis show that the registration errors are consistent with those made in the study using synthetic data.
