Abstract
The position calculation system has position and energy calculators for each scintillation event. After correcting the position and energy values using tables, non-uniform random distribution variance values are added to the position and energy values with the variance added being a product of the random number and a constant precalibrated for the given position. The variance injected position and energy values have a more uniform resolution and substantially remove artifact characteristics in the scintillation camera's image.
