| Outline of Final Research Achievements |
The computer-aided radiotherapy planning system (CARPS) has been developed to search similar cases among the previously registered 81 cases and to apply the previous beam directions to new cases, semi-automatically.
Four planners performed stereotactic body radiation therapy (SBRT) planning of 8 lung cancer cases with and without CARPS. The elapsed time of these procedure are measured as the planning time.We evaluated the planning time, dosimetric parameters, and subjective evaluation of planners. The planning times with CARPS were shorter than those without CARPS in all planners. There was significant difference between two groups. The dosimetric parameters were equivalent in two groups. In conclusion, the SBRT planning with CARPS using previous similar cases can reduce the planning time with the equivalent dosimetric parameters to those without CARPS.
