Description

근접 치료를 위한 선량 측정 장치Dosage measuring device for brachytherapy
본 발명은 근접 치료를 위한 선량 측정 장치에 관한 것으로, 특히 조사되는 방사선량의 선량 분포를 측정할 수 있는 선량 측정 장치에 관한 것이다.The present invention relates to a dose measuring device for brachytherapy, and more particularly, to a dose measuring device capable of measuring a dose distribution of an irradiated radiation dose.
본 연구는 교육부(정부)의 재원으로 한국연구재단의 지원을 받아 수행된 연구사업의 고-분해능 방사선치료선량 평가를 위한 방사선 고강도 반도체 센서 개발 및 이용(No. 2018R1D1A1B07050217)과 관련된다.This study is related to the development and use of high-intensity radiation semiconductor sensors (No. 2018R1D1A1B07050217) for the evaluation of high-resolution radiation therapy doses for research projects conducted with the support of the National Research Foundation of Korea with funding from the Ministry of Education (Government).
암 환자의 방사선치료 방법으로써 원격방사선치료법과 근접방사선치료법이 일반적이다. 여기서, 원격방사선치료법은 환자의 외부에서 방사선을 환자에게 조사하여 암세포를 제거하는 치료법이며, 근접방사선치료법은 환자의 체내 환부로 방사선 동위원소를 영구/일시적으로 삽입하여 체내의 암 세포를 제거하는 치료법이다. As radiotherapy methods for cancer patients, remote radiation therapy and brachytherapy are common. Here, the remote radiation treatment method is a treatment that removes cancer cells by irradiating the patient with radiation from the outside of the patient, and the proximity radiation treatment method removes cancer cells in the body by permanently/temporally inserting a radioactive isotope into the affected part of the patient's body. to be.
한편, 선형가속기를 이용한 외부 방사선치료는 치료 전 환자 치료 선량의 품질 관리를 위해 선량이 원하는 부위에 적확히 들어가는지 확인한 후에 진행되는 것이 일반적이다. 마찬가지로, 방사선 동위원소를 인체에 직접 삽입하는 근접 방사선 치료의 경우에도 치료 전 환자 치료 선량 품질 관리와 더불어, 치료 중 정확한 선량 전달이 되었는지를 확인할 수 있는 선량 관리가 요구된다. On the other hand, external radiation therapy using a linear accelerator is generally performed after confirming that the dose is correctly entered into the desired area for quality control of the patient's therapeutic dose before treatment. Likewise, in the case of brachytherapy in which a radioactive isotope is directly inserted into the human body, it is required not only to control the patient dose quality before treatment, but also to control the dose to confirm whether the correct dose was delivered during treatment.
그러나, 근접방사선치료의 경우, 환자가 받는 선량 검출을 위한 장비가 미비함으로써, 독립적인 선량 관리가 어려우므로 환자에 정확하게 방사선 선량을 적용하기 위하여 실시간 선량 측정을 통해 방사선 치료 및 관리의 정확성을 향상시킬 수 있는 기술이 필요하다.However, in the case of brachytherapy, since the equipment for detecting the dose received by the patient is insufficient, independent dose management is difficult. Therefore, in order to accurately apply the radiation dose to the patient, the accuracy of radiation treatment and management will be improved through real-time dose measurement. You need skills to be able to.
