What is 3-D conformal radiation therapy?

3-D conformal radiation therapy is a form of radiation therapy used to treat different types of cancer. The imaging technology helps shape the radiation treatment beam to the shape of the tumor. Conformal radiation therapy gives doctors more control when treating tumors.

Special computers use CT imaging scans to create 3-D maps of the location of the cancer in the body. The system permits the delivery of radiation from several directions, and the beams can then be shaped, or conformed, to match the shape of the cancer. Conformal radiation therapy limits radiation exposure to nearby healthy tissue as well as the tissue in the beam's path.
