2018年の診療報酬改定により画像誘導放射線治療（image guided radiotherapy：IGRT）加算として左乳癌に対する体表面照合が認められて以降，体表面画像誘導放射線治療（surface–guided radiotherapy：SGRT）は我が国においても多くの施設で導入が進んでいる。

Our team have performed surface–guided radiotherapy（SGRT）for various treatment sites since the introduction of Catalyst^TM in 2018, and Catalyst^TM SGRT is highly effective in assisting the setup of patients treated and managing intra–fractional motion due to its extremely wide measurement range and response. In this article, we present critical features and functions of Catalyst^TM, some points to be kept in mind in clinical practice, and outline representative cases for implementation of SGRT.
