Abstract
A radiation detection device () is used in a nuclear medicine diagnosis apparatus, and includes a plurality of scintillators (), a semiconductor light-receiving device (SiPM), a position detection circuit (), and a timing detection circuit (). Each of the scintillators converts a gamma ray emitted from a subject () into fluorescence. The semiconductor light-receiving device is provided corresponding to each of the scintillators and converts the fluorescence converted by a corresponding one of the scintillators into an electrical signal. The position detection circuit specifies a gamma ray detection position in the scintillators based on the electrical signal from the semiconductor light-receiving device. The timing detection circuit is connected to an anode of the semiconductor light-receiving device, and specifies time information corresponding to a time of occurrence of an event in which the gamma ray is detected.
