Abstract:
1. A method of registering a functional image to a structural diagnostic image comprising: acquiring a first functional image of a biological sample based on a first radiopharmaceutical, wherein the first radiopharmaceutical causes the first functional image to show a desired function; acquiring a second functional image of the biological sample based on a second radiopharmaceutical, wherein the second radiopharmaceutical causes the second functional image to show a detectable amount of structural information associated with the biological sample, and wherein the second functional image has a known positional relationship to the first functional image; providing a structural image of the biological sample; determining a first mapping transformation between the second functional image and the structural image based on at least a portion of the detectable amount of structural information; and determining a second mapping transformation between the first functional image and the structural image based on the first mapping transformation and the known positional relationship.
