3-D CONFORMAL RADIATION THERAPY
PRECISE TREATMENT PLANNING
Our department provides state of the art conformal/precision radiation therapy, also known as 3-D Conformal Radiation Therapy (3DCRT), for tumors throughout the body. This therapy uses multiple carefully shaped and positioned beams of radiation that allow the high dose region of the radiation plan to closely “conform” to the shape of the tumor, thereby minimizing the radiation to adjacent normal structures. 3DCRT is used extensively for patients needing treatment for cancers of the prostate, lung, head + neck, brain, GI tract and others.
3DCRT is made possible by the use of modern tumor imaging and advanced software tools. A detailed CT scan, with the patient in the treatment position, is obtained for the treatment planning process. On each CT image, the tumor and normal tissues are carefully outlined by the radiation oncologist. These outlines are then reconstructed and displayed as a 3 dimensional image on the computer monitor. This 3-D visualization allows the radiation oncologist to choose various radiation beam arrangements, and to carefully shape each beam to maximally cover the tumor with radiation, and minimize the radiation to surrounding normal tissues.
