Abstract
A method for calibrating a non-pixelated gamma camera is provided, wherein the method includes determining a linearity map and a uniformity map of a reference isotope; and determining a linearity map and uniformity map of another isotope. Delta maps are calculated based on the maps of the reference isotope and the maps of the other isotope. During recalibration, new maps of the reference isotope are determined, thereby enabling new maps of the other isotope to be created based on the delta maps.
