The physicist and a radiology resident who is assigned for an hour to learn about planning oncology radiation are at the computer. The computerized axial tomography film is on a digitizing pad. Internal structures, including tumor volume are input into the computer, which reconstructs the film image into numerical descriptions and displays this on the screen. Once the computer has the patient's contour, the physicist can call up beam data and see how the radiation can be distributed in that patient. This plan for treatment is used as a blueprint. A simulation of this plan with x-rays verifies the strategy before the patient is treated. The resident was so intrigued by this careful and advanced procedure that she stayed much longer than she had intended.
