3D Conformal Radiation Therapy (3D CRT) is a type of cancer treatment that uses advanced imaging technology to create a three-dimensional map of a tumor. This allows doctors to precisely target the tumor while minimizing exposure to surrounding healthy tissues. By shaping the radiation beams to conform to the tumor's contours, 3D CRT enhances treatment effectiveness and reduces side effects. During the procedure, patients typically lie on a treatment table while a machine delivers radiation from multiple angles. Radiation oncologists carefully plan the treatment, ensuring that the total dose of radiation is delivered accurately over several sessions, improving the chances of successful outcomes.
