Introduction
Registration found its application in medical imaging due to the fact that physi-
cians are frequently confronted with the practical problem of registering medical
images. Medical registration techniques have recently been extended to relate
multimodal images which makes it possible to superimpose features from differ-
ent imaging studies. Registration techniques have been also used in stereotactic
surgery and stereotactic radiosurgery that require images to be registered with
the physical space occupied by the patient during surgery. New interactive,
image-guided surgery techniques use image-to-physical space registration to
track the changing surgical position on a display of the preoperative image sets
of the patient. In such applications, the speed of convergence of the registration
technique is of major importance.
