In radiotherapy, spatio-temporal instability of target and normal structure andor geometric uncertainty of patient setup are one of reasons for treatment failure. Especially, in sophisticated radiotherapy such as intensity-modulated radiotherapy and stereotactic radiotherapy, the devices and methods of increasing the precision and accuracy are needed. Image-guidance for radiotherapy is devised to i) reduce the difference between the predicted and measured position for setup of the patients (to reduce interfractional error), ii) monitor and correct intrafractional error caused mainly from the internal motion of tumor and normal tissue, and iii) real-time tumormarker tracking. By the introduction of image-guided radiotherapy (IGRT), the safety margin can be reduced, and therefore dose escalation can be implemented safely.総説Review Article
