Image Guided Radiotherapy (IGRT)
In modern radiation therapy, accurate placement and shaping of the beams is essential. Technologies such as 3D conformal therapy and IMRT depend on precision guidance, making Image Guided Radiotherapy (IGRT) an integral part of our treatment approach. IGRT takes a picture of the radiation beam during treatment, showing its exact location on the patient. Our new therapy machines are equipped with on-board imaging systems, the latest advance in treatment technology. On-board imaging enables us to take diagnostic quality x-rays or CT images of patients while they are on the treatment couch and in position for therapy. These images are correlated to those generated from our 3D Treatment Planning Systems and used to minimize daily changes in patient position, and in some cases compensate for the normal shifting of organs within the body as well. Because of our advanced equipment, we are able to offer this technology to the vast majority of our patients on every treatment day. In short, on-board imaging is making a difference in quality of care by improving the accuracy of daily treatments.
