Conformal Radiation Therapy (CRT)
The imaging technology used by radiation oncologists at Penn Medicine helps shape the radiation treatment beam to the shape of the tumor. Known as conformal radiation therapy, this technology gives doctors more control when treating tumors.
In conformal radiation, a special computer uses 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.
The Advantage to Patients
The advantages of conformal radiation therapy include:
- Maximum radiation exposure to the cancer
- Less radiation exposure to healthy tissue
