3D Conformal Radiotherapy

In 3D conformal radiotherapy, the radiation oncologist shapes and precisely delivers high-energy x-ray beams to the disease site while optimally protecting normal tissues. 3D conformal radiotherapy uses high-speed computers to extract the CT/MRI data, perform three-dimensional isodose calculations, and overlay the data for the radiation oncologist’s and medical physicist’s analysis. This technique allows more accurate and conformal treatment planning so that there is adequate coverage of the tumor with minimal toxicity to the adjacent healthy tissues.
