1. A radiation detector comprising:
a scintillator array including a plurality of scintillator pixels each configured to convert radiation into light;
a sensor array including a plurality of detection elements each configured to detect the light;
electronic circuitry configured to output digital data based on signals output from the detection elements;
a switch provided between the sensor array and the electronic circuitry; and
control circuitry configured to control the switch based on a positional relation between the sensor array and the scintillator array.
