POSITION-SENSITIVE GAMMA DETECTORS

摘要

Various embodiments can include apparatus and methods to operate and provide a position-sensitive detector. In various embodiments, a detector may include an illuminating device, a photodetector array, and a number of elemental circuit units, where an arrangement of the number of elemental circuit units with the photodetector array can provide a mechanism to identify a position of a light generating event in the illuminating device. Additional apparatus, systems, and methods are disclosed.

主权项

1. An apparatus comprising:
an illuminating device structured to produce a light signal in response to reception of a gamma ray at a position in the illuminating device; an array of photodetectors arranged to receive the light signal and to provide a detected signal; a number of elemental circuit units coupled to the array of photodetectors such that the detected signal is divided into two signals by the elemental circuit units, a first signal of the two signals correlated to a first number of the number of elemental circuit units and a second signal of the two signals correlated to a second number of the number of elemental circuit units; a processing unit structured to determine the position relative to a length of the illuminating device based on the first number, the second number, and a ratio of the two signals.
