- Abstract:
- Abstract: Objective To evaluate the accuracy and clinical feasibility of dose calculation by treatment planning system (TPS)DeepPlan. Methods The accuracy verification of dose algorithm was mainly to measure and verify the examples of YY 0775 report and the YY/T 0889 report. The clinical case verification was based on the clinical plans actually implemented in Pinnacle TPS for 9 cases of prostate tumor, 13 cases of chest tumor and 5 cases of head-neck tumor. In the experiment, the optimized sub-fields and other information of the original plan of each case were directly imported into DeepPlan for dose re-calculation. The dose profiles of target areas and organs-of-risk were recorded and compared between different TPS, and the gamma analysis was conducted on calculated results using PTW VeriSoft software. Results DeepPlan photon dose algorithm met the criteria of dose accuracy, and its errors in all test examples of YY 0775 report were within 2%. The gamma passing rates of all test examples of YY/T 0889 report were above 96.8%, and the average gamma passing rate of composite field was 98.1%. The average 2D gamma passing rate at isocenter layer were 97.6%, 98.7% and 98.6% in prostate tumor cases, chest tumor cases and head-neck tumor cases, respectively, and the average 3D gamma passing rate were 96.9%, 98.3% and 98.8%, respectively. Conclusion The actual measurement through the phantom and the test on clinical cases verify the accuracy of the photon dose calculation by DeepPlan and the its feasibility in clinical application.
