Imaging characteristics of gamma-ray collimators.
Imaging characteristics of 43 commercial gamma-ray collimators for rectillinear scanners are measured. The modulation transfer functions, plane sensitivity, full width at half maximum, depth-of-field, and focal length for each collimator are reported. The products of all five companies examined appear to represent the current state of the art.
