Abstract
An image of a patient taken through X-ray computed tomography or the like is registered to physical measurements taken on the patient's body. Different parts of the patient's body are given different numerical weights; for example, if bone measurements are deemed to be more accurate than skin measurements, the bones can be given a higher weight than the skin. The weights are used in an iterative registration process to determine a rigid body transformation function. The transformation function is used in robot-assisted surgical procedures, stereotactic procedures or the like.
