Apparatus and method for verifying radiation dose using patient-specific tumor-shaped scintillation

An apparatus for verifying a radiation dose using a patient-specific tumor-shaped scintillator comprising:

• a processor;
• and
• a memory connected to the processor,
• wherein the memory stores program instructions executable by the processor to calculate a dose absorbed in a 3D tumor-shaped scintillator when a plurality of calibration shots are irradiated through Monte Carlo simulation,
• measure an output current corresponding to visible light generated by the 3D tumor-shaped scintillator attached to a modular dose verification device,
• determine a calibration factor for converting the output current into the dose, and
• calculate a total dose absorbed in the 3D tumor-shaped scintillator by irradiating radiation used in a treatment plan using the determined calibration factor.

A method for verifying a radiation dose using a patient-specific tumor-shaped scintillator comprising the steps of:

• attaching a 3D tumor-shaped scintillator having a guide to a probe adapter;
• coupling the probe adaptor to a receiving portion;
• irradiating a plurality of calibration shots to the 3D tumor-shaped scintillator;
• converting visible light generated by the 3D tumor-shaped scintillator into an electric signal by the plurality of calibration shots and amplifying the converted electric signal;
• measuring an output current using the electric signal;
• calculating a dose absorbed in the 3D tumor-shaped scintillator when the plurality of calibration shots are irradiated through Monte Carlo simulation;
• determining a calibration factor for converting the output current into the dose;
• and
• calculating a total dose absorbed in the 3D tumor-shaped scintillator by irradiating radiation used in a treatment plan using the determined calibration factor.
