1. A method of registering SPECT images with CT or MR images, comprising the steps of:
- (A) aligning and immobilizing a human torso to be imaged on a support means;
(B) uniquely marking a cross section of the imaged torso by placing at least a portion of said human torso proximate to a contrasting marker means encased in an inert material comprising the support means;
(C) imaging said human torso using two or more imaging techniques to produce at least two images of said human torso to be imaged; and
(D) registering said at least two images of said human torso to be imaged to produce a coherent image of said human torso to be imaged.

Abstract
The invention is a machine based alignment system for imaging with a contrasting marker (fiducial marker) attached to a support means for providing a set of markings which uniquely identify each cross-section of an imaged object in relation to other registered images.
The invention also provides a method for using the alignment system.
