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.
Claims20
A nuclear medicine examination apparatus, comprising:
- a pixel-type radiation detection device configured to detect information of a charged particle generated by Compton scattering in a gas;
- one or a plurality of sensors configured to detect a physical amount of the gas;
- and
- a controller configured to control at least one of the physical amount and a composition of the gas based on output signals from the one or plurality of sensors.
A nuclear medicine examination method of specifying a position of a radiation source emitted from a specimen by detecting a charged particle generated by Compton scattering in a gas,
- the method comprising:
- characterized by comprising adjusting a pressure of a gas that causes the Compton scattering when detecting radiation emitted from the radiation source.
A nuclear medicine examination method of specifying a position of a radiation source emitted from a specimen by detecting a charged particle generated by Compton scattering in a gas,
- the method comprising:
- characterized by comprising adjusting a type of gas that causes the Compton scattering when detecting radiation emitted from the radiation source.
