A Directional Algorithm For An Electronically-Collimated Radiation Detector (Ecrd), Adam Lackie

LSU Master's Theses

An electronically-collimated radiation detector (ECRD) is being developed to be used for locating radiation sources, e.g. for intraoperative localization of sentinel lymph nodes, or for public safety applications. The design emphasizes a compact, portable detector with a wide field of view. Typical probes provide either high sensitivity but no directional information when uncollimated, or directional information but poor detection efficiency when collimated. The ECRD design provides high sensitivity to the presence of radiation because it lacks physical collimation, and simultaneously provides directional information using electronic collimation. Intended to be a hand-held device, the ECRD front end comprises an array of …
