Abstract

We developed a wireless gamma-ray probe based on radiation photon counting method to diagnose and detect remaining lesions after surgery, and its effectiveness was evaluated using calibration sources and a phantom. The probe was designed and miniaturized using a semi-conductor-based radiation sensor, and a Bluetooth remote communication module was used to implement the wireless diagnosis and detection system. Moreover, a remote monitoring system was implemented to monitor affected areas during diagnosis and surgery. To assess the effectiveness of the developed probe in this study, calibration sources $^{57}Co$, $^{133}Ba$, $^{22}Na$ and $^{137}Cs$ and a chicken breast phantom were used. Furthermore, the probe's detection response to gamma ray was confirmed through evaluation. Its clinical applicability was verified by assessing the response linearity and detection direction according to gamma-ray intensity, as well as the detection efficiency according to the depth of the gamma source in the phantom.

연구에서는 진단 및 수술 후 잔여병소의 검출을 위하여 방사선계수 방식의 무선 감마선 프로브를 개발하고, 교정선원과 팬텀을 이용하여 그 유용성을 평가 하였다. 반도체기반 방사선센서를 사용하여 프로브 설계 및 소형화 하였으며, 블루투스 원격통신 모듈을 사용하여 진단 및 검출 시스템의 무선화를 구현하였다. 또한 진단 및 수술 시 환부의 모니터링이 가능한 원격모니터링 시스템을 구현하였다. 개발된 프로브의 유용성 평가를 위해 교정선원 $^{57}Co$, $^{133}Ba$, $^{22}Na$, $^{137}Cs$과 닭 가슴살 팬텀을 사용하였다. 평가를 통해 감마선에 대한 프로브의 검출 반응성을 확인하였고, 감마선 세기에 따른 응답 선형성과 검출 방향성, 팬텀 내 선원 깊이에 따른 프로브의 검출효율을 평가를 통해 실증적인 임상에서의 적용 가능성을 확인하였다.
