Scintillation camera position calculation with uniform resolution using variance injection

摘要

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.
