Intensity modulated radiation therapy technology / 医疗卫生装备

ABSTRACT

On the basis of generally stereotactic radiotherapy technology,intensity modulated radiation therapy technology has been developed greatly since 1990's.This technology is to improve the radiation dose distribution in the target so that the high dose area is more conformal for the three-dimentional shape of the target and the radiation dose in the normal organs and tissue around the target decreases.The characteristic of this new technology is discussed systematically in this paper.
