DESIGN OF A MODIFIED UNIFORM REDUNDANT-ARRAY MASK FOR PORTABLE GAMMA CAMERAS

Uniform redundant-array masks have been reported as good lenses to form the image of gamma sources, with the correlation between the mask-aperture matrix and, the shadows projected on a static position-sensitive detector. We present a modified uniform redundant-array configuration suitable for porta...

Description
Summary:Uniform redundant-array masks have been reported as good lenses to form the image of gamma sources, with the correlation between the mask-aperture matrix and, the shadows projected on a static position-sensitive detector. We present a modified uniform redundant-array configuration suitable for portable and small-size gamma-cameras; its ability to reconstruct the image of several sources is analyzed. We have carried out a Montecarlo simulation of the gamma interactions in the mask, defining the expected response of the correlation process and comparing it with that achieved with the usual uniform redundant-array configurations.
