Abstract

Recent developments of image guided radiation therapy (IGRT), especially the On Board Imaging (OBI) system and the cone beam CT (CBCT), enable the radiation treatment more accurate and reliable. IGRT is widely used in the radiation therapy as a standard of care. Use of IGRT is even expected to increase in the near future. IGRT is only beneficial to patients when it is used with proper considerations of safety and appropriateness of the techniques. Institutional procedure should be developed based on the clinical need and the deep understanding of the system before applying the new technique to the clinic. Comprehensive QA program should be established before to the clinic and imaging dose should be considered when preparing the departmental practice guidelines for IGRT.

Cone Beam CT (CBCT)와 On Board Imaging (OBI)를 비롯하여 최근에 개발되고 있는 방사선 치료용 영상 장치(Image Guided Radiation Therapy, IGRT)의 사용으로 방사선 치료가 더욱 정확해지고 있다. 점차 사용 범위가 넓어지면서 표준치료법으로 자리잡았고 앞으로 사용하는 기관과 빈도가 더 늘어날 것으로 전망한다. IGRT는 그러나 안전하고 용도에 맞게 사용할 때만 효능을 볼 수 있다. 이를 위해 IGRT를 임상에 적용하기 전에 장치의 특성을 이해하고 병원의 임상 요구에 적합한 지침서를 미리 만들 필요가 있다. QA 프로그램과 환자가 받을 추가 선량에 대한 고려도 미리 준비해둘 필요가 있다.
