Patent ID: 7105824

Claim:
A method of digitally constructing and visually displaying brain function activity comprising the steps of: injecting a radioactive isotope into a source brain to facilitate the emission of gamma radiation from the source brain; scanning the gamma radiation emitted along a first plane of the brain and storing a respective first distribution of collected counts of radioactivity as actual scan data in an electronic storage device; digitally reconstructing a brain function image from a comparison between the actual scan data of the brain source and a theoretical scan of the brain source; and visually displaying the brain function image as a representation of brain function activity; wherein the digitally reconstructing step further comprises the steps of estimating a second distribution of radioactivity in the source brain and performing a simulated scan of the estimated second distribution to obtain the theoretical scan; and wherein the step of the reiterated comparison between theoretical and actual scan data further comprises the steps of comparing the theoretical scan with the actual scan data and modifying the estimated second distribution to obtain a solution gamma radiation distribution which more closely match the actual scan data; and further comprising the step of determining whether the solution compares to the actual scan data within a desired statistical noise.
