Image-guided Radiation Therapy (IGRT)
IGRT is a new approach to delivering radiation therapy that allows for more accurate delivery of radiation to the target tissue. IGRT involves imaging during the course of radiation treatment. A computer compares images taken at the time of treatment to images taken during the planning phase. Through this process, IGRT is able to account for changes in the patient’s body or position that may shift the exact location of the cancer. This allows increased accuracy of very complex treatment approaches. It also provides documentation of the degree of accuracy. IGRT is used in conjunction with EBRT, 3D-CRT or IMRT.
