Abstract: Proposed is an apparatus for verifying a radiation dose using a patient-specific tumor-shaped scintillator including 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; and a current electrometer measuring an output current by inputting the electric signal of the photomultiplier tube.

Abstract: The present disclosure relates to a method of measuring an absorbed dose of radiation in small irradiation fields. The method of measuring an absorbed dose of radiation in small irradiation fields, includes an acquisition step of acquiring absorbed dose distribution data of radiation; a determination step of determining a region where an absorbed dose of radiation of a predetermined ratio or more is absorbed based on the absorbed dose distribution data of radiation; a formation step of forming a scintillator having a shape in which a plurality of hexahedral cells are coupled to have a shape matching the region; a measurement step of measuring a absorbed dose of radiation irradiating the scintillator from a radiation irradiation device; and a calculation step of calculating the absorbed dose of radiation of the cell at a predetermined position by using predetermined Equations.
