Abstract
-
Some modern accerelators provide a dual energy for photon beam treatment. The main advantages of dual energy in the treatment of rectosigmoid or rectal cancer are as follows. Dose in the critical organ such as small intestine, bladder and genital organ are reduced. Presacral and perineal area is fully covered. Dose distribution analysis such as calculation of dose in a target volume, isocenter, Dmax and dose spectrum in any region of interest are possible. Examples of plan are given and results are discussed.
