| Research Abstract |
In radiation therapy, medical accidents which are over and under dose of the irradiation mistake occur frequently. To reduce these accidents and to increase accuracy of radiation therapy, we are developing an implantable real time mycrodosimetly system. Scintillator is used as a sensor, which is implanted in the patient body/or tumor generates scintillation during the irradiation. And the doses of radiation are monitored by measuring the intensity of scintillation using CCD camera. As a first step, we made a miniaturized scintillation measurement system that is involves scintillator, pig meat as a phantom and measurement instruments. We got the data that that through a thickness of 2cm meet, 694nm of scintillation is proportionally generated from scintillators when the LINAC is working at the dose rate of 4Gy/min. Also we successfully got these data with wireless way at a distance of 170cm between scintillator and detection device (CCD camera).
