In order to view two volumes in relation to each other, they have to be image registered.
Image landmark registration is a simple process where a number of points (landmarks) are defined on the same locations in two volumes. The landmarks are then matched by an algorithm, and the volumes are thus registered. The two volumes are called fixed and moving in the registration process.
Before performing an image registration, you must determine which landmarks you want to use. They should be clearly identifiable anatomical points, alternatively artificial fiducials can be attached to the patient prior to image acquisition. 4 landmarks are the minimum recommended.
