Abstract:
Fourteen patients with pancreatic carcinoma were selected. Two treatment plans were designed for each patient, including gamma knife and Tomotherapy. The dose characteristics were evaluated by DVH and were compared. The results showed that the gamma knife plan had the higher maximal and mean target dose than Tomotherapy. Body gamma knife can increase the target dose significantly, and decrease the OAR dose. Tomotherapy had excellent dose-target conformality, and it can control doses of duodenum and stomach easily, but it had larger low dose region.
