摘      要：BACKGROUNDS AND PURPOSES:Intensity modulated radiotherapy(IMRT) and stereotactic irradiation have become common as a new radiotherapy technique for treatment of *** modalities generally use multiple arc or fixed-portal radiation beams,and radiation beams are exposed *** techniques often require 30 rain or a longer time in one treatment session for precise positioning of *** of irradiation time may reduce a radiation effect,and evokes a major concern for the dose rate ***,it is needed to clarify the
