Abstract
Image-guided radiotherapy (IGRT) has undergone a continuous evolution of refinements leading up to the sophisticated techniques currently implemented as standard treatment, in radiation oncology clinics. This paper aims to summarize, in a general fashion, the key advances that have resulted in the ability of radiation oncologists to deliver increased radiotherapy doses to tumors, reduce doses to normal tissues, limit treatment related toxicity/complications, and increase patient convenience.
