  • IGRT is a step forward of IMRT in which various biological and anatomical imaging techniques are integrated into the radiation therapy process. The overall goal of IGRT is to target tumors more accurately while better sparing the normal tissues. The definition of target volume is undergoing a change on account of advancements in imaging modalities.
