Collimator View Angles Evaluated with Script
• Scripted CAD model calculates view cones of collimated detectors.
• Detector area divided into “pixels”
• Script evaluates how many “pixels” are unobstructed for particle incident with pitch angles !, ".
• Collimator view has “shoulders” because of finite size effect.
