ABSTRACT:
A method of localizing a scintillation event in a scintillation camera is disclosed. The method comprises steps of (a) assuming an ideal situation where the photomultiplier tubes of the camera behave ideally according to an ideal position-intensity distribution curve and an ideal locus for each PM tube is determined from the ideal position-intensity distribution curve such that all of the ideal loci intersect at a single point, which corresponds to the position of a scintillation event; (b) establishing a position function representing the single point, the position function depending on the coordinates of the PM tubes and the radii of ideal loci; (c) when a scintillation event occurs, measuring outputs of the PM tubes; (d) determining radii of real loci for the PM tubes by using the outputs of the PM tubes and real position-intensity distribution curves; and (e) substituting into the position function the coordinates of the PM tubes, and the radii of the real loci for the radii of the ideal loci in order to estimate the position of the scintillation event.
