摘要： A radiation detector according to an embodiment includes a scintillator array, a sensor array, electronic circuitry, a switch, and control circuitry. The scintillator array includes a plurality of scintillator pixels each configured to convert radiation into light. The sensor array includes a plurality of detection elements each configured to detect the light. The electronic circuitry is configured to output digital data on the basis of signals output from the detection elements. The switch is provided between the sensor array and the electronic circuitry. The control circuitry is configured to control the switch on the basis of a positional relation between the sensor array and the scintillator array.

摘要： According to an embodiment, a radiation detector includes scintillator elements, dielectric multilayer films, and a metal reflective layer. The scintillator elements are arranged in a two-dimensional grid pattern. The dielectric multilayer films are provided between adjacent scintillator elements such that a dielectric multilayer film is adjacent to one of said scintillator elements. The metal reflective layer is provided between adjacent dielectric multilayer films.
