The use of CT scanning in the treatment simulation process permits the development of a three-dimensional treatment plan that allows the design of a complex combination of radiation beams focusing on a cancer. This is particularly useful in treating cancers that are adjacent to vital structures or near organs that are sensitive to the effects of radiation. Completion of a 3D treatment plan requires CT scanning equipment, essential computer hardware and software, as well as skilled radiation oncologists and radiation dosimetrists.
