Abstract:
A medical system (28) for normalization correction of an imaging system (10) includes a detector geometry correction unit (44), a crystal efficiency unit (46), and a normalization unit (54). The detector geometry correction unit (44) mathematically calculates a detector geometry correction component for a type of scanner (12) of interest. The crystal efficiency unit (46) configured to empirically determine a crystal efficiency component for at least one individual scanner (12). The normalization unit (54) generates a normalization data set (56) which corresponds to a normalization correction factor of the at least one individual scanner (12) in accordance with the detector geometry correction component and the crystal efficiency component.
