Claim Text:
1. A medical system for normalization correction of an imaging system , comprising: a first modeling unit which generates a first model simulating characteristics of a type of scanner of interest; a second modeling unit which generates a second model of a planar source detector geometry phantom; a normalization data simulator configured to simulate normalization data using the first model and using the second model; a detector geometry correction unit configured to mathematically calculate a detector geometry correction component for a type of scanner of interest; and a crystal efficiency unit configured to empirically determine a crystal efficiency component for at least one individual scanner using the simulated normalization data; a normalization unit which generates a normalization data set corresponding to a normalization correction factor of the at least one individual scanner in accordance with the detector geometry correction component and the crystal efficiency component.
