Claim Text:
1. A method for forming a multi-pinhole collimator, the method comprising: calculating a projection size (D) for different pinhole numbers (n) for a predetermined field-of-view (FOV) (d) by arranging a plurality of projections into a pattern; configuring the pattern to utilize a whole detector with maximized packing density, minimum truncation to provide a projection overlap below a predetermined limit; modifying a number of pinholes to calculate a collimator length; calculating an acceptance angle and aperture size; adding sensitivities for individual pinholes to obtain a total sensitivity for a given pinhole number; selecting an optimized multi-pinhole configuration by maximizing the total sensitivity for a predetermined target resolution (R producing the multi-pinhole collimator comprising an aperture plate having a plurality of pinholes formed therein and having a pinhole configuration corresponding to the selected optimized multi-pinhole configuration.
