1. An apparatus for verifying a radiation dose using a patient-specific tumor-shaped scintillator comprising:
a probe adapter to which a 3D tumor-shaped scintillator having a guide is attached;
a receiving portion to which the probe adapter is detachably coupled;
a light guide which extends from the receiving portion and includes optical fiber transmitting visible light generated by irradiating radiation in the 3D tumor-shaped scintillator;
a photomultiplier tube converting the visible light transmitted from the light guide into an electric signal and amplifying the converted electric signal;
a current electrometer measuring an output current by inputting the electric signal of the photomultiplier tube; and
a processor which is connected to a memory storing program instructions, and calculates a dose absorbed in the 3D tumor-shaped scintillator when a plurality of calibration shots are irradiated through Monte Carlo simulation, determines a calibration factor for converting the output current into the dose, and calculates a total dose absorbed in the 3D tumor-shaped scintillator by irradiating radiation used in a treatment plan using the determined calibration factor.
