Abstract: 

Background: This investigation was conducted to evaluate the results of these three different techniques including: Supine position with full bladder and water bag on reducing the small intestine surface which is exposed to radiation about the patients involved in the cancers of prostate, cervix, uterus and rectum.
Materials and Methods: Out of 35 patients in pelvic cancer who referred to the radiation oncology department of Imam Khomeini hospital in Tehran in year 2001: 11 males, 24 females with mean ages of 51.36 years old and the mean weight of 62.5 kg: 10 potients with cancers of rectum, 13 with cervix, 8 with uterus and 4 ones with prostate, before receiving radiation all these patients were simulated with three different techniques and the possible radiated surface of the small intestine were calculated and compared with each other. Results: At this study by investigating the mean small intestine surface of 31 patients out of 35 ones including on supine position and an empty bladder/ prone position with full bladder/ prone position with full bladder and water bag, the following results were obtained: 215. 48/ 159.4/and 122.97 cm2.
Conclusion: By comparing the results of the mentioned three different simulation techniques, patients who were simulated on prone position with full bladder and water bag, the radiated surface of the small intestine was 43% lower than the patients were simulated on supine position and an empty bladder, and 23% lower than the patients were simulated on prone position and full bladder. These findings are satisfactory and comparable with belly board, ... technique simulation in which the reducing volume of the small intestine was 50%.
