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.
