Abstract

See full text

The necessary detector configuration and mathematical algorithms to implement a lateral (side-viewing) field of view in a gamma detection probe designed for laparoscopic use is disclosed. For this application, the diameter of the probe is limited to 12 mm. A hybrid collimation design, using a combination of both electronic collimation and metallic shielding, allows the probe to detect gamma emissions form 15 KeV-1.0 MeV. In the lower energy range, the 1.52 mm tungsten shielding is sufficient to collimate the primary detector. Two additional detectors are used to provide electronic collimation and depth detection. The upper energy limit of 1.0 MeV is imposed to exclude the possibility of electron-positron pair production which occurs at energies of 1.022 MeV and greater.
