Abstract: A radiation image forming apparatus includes a detection unit including a plurality of Compton cameras. Each of the plurality of Compton cameras including a radiation detection device that includes a plurality of pixels, each configured to detect an electron generated by the track of a recoil electron generated by Compton scattering, and is configured to output a detection signal configured to specify the position of a pixel that has detected the electron and a time when the pixel has detected the electron, and a detection module configured to detect the incident position of scattered γ rays generated by the Compton scattering. The plurality of the Compton cameras arranged annularly to surround a region in which a specimen is placed.

Abstract: A nuclear medicine examination apparatus is a nuclear medicine examination apparatus incorporating a Compton camera using gas amplification. The Compton camera has a chamber in which a gas is sealed. The nuclear medicine examination apparatus includes sensors that output signals each representing a gas state in the chamber and a controller that controls the gas state in the chamber on the basis of output signals from the sensors.
