Before starting radiation therapy, a physician needs to know the location and size of the cancerous tumor, the radiation doses required to treat the tumor, and the positioning of the radiation beams to target the tumor. With the help of imaging and computerized reconstruction techniques, the physician creates a simulated field that closely resembles the location and size of the tumor in the body. The CT or MRI data of the patient is fed into a simulator that recreates the image of the tumor and its surrounding area. With the help of the simulator, the physician decides the ports where the radiation beams should enter the body so as to hit the tumor with maximum accuracy.
