| Abstract: | Metal oxide semiconductor field effect transistor (MOSFET) detector was used to measure radiation dose in space initially, and it was applied to medical domain in recent years. MOSFET detector had extent prospect in clinical field because it had the advantages that other nomal detectors couldn' t compare with. This article introduced the application of MOSFET detector in radiotherapy by summarizing its basic principle, the principle of measuring dose and the relative characteristics. |
