<p>PURPOSE: A digital silicon photomultiplier detector cell improves energy resolution by counting radiation at the outside in real time regardless of memory capacity and measuring the amount of the radiation. CONSTITUTION: A scintillator (110) generates light by receiving radiation. A detector unit (130) generates a digitalized detection signal by receiving light of a wavelength in a specific range. The detector unit includes a photodiode and an active reset part connected to the cathode of the photodiode. A read-out unit (150) transmits a generated output signal corresponding to the detection signal generated in the detector signal to an external circuit. The read-out unit does not store the detection signal within a detector cell.</p>
