瓦里安Eclipse计划系统中基于云计算的ARC技术的剂量计算时间的探讨
Discussion on the Dose Calculation Time of ARC Technique Based on Cloud Computing in Varian Eclipse Treatment Planning System
摘要
Abstract
Objective To explore how to shorten dose calculation time of cloud computing based on ARC technique. Methods Fifteen patients with nasopharyngeal carcinoma were randomly selected. ARC technique was chosen to do the plan and four arc fields were used. Two point five mm was selected as calculation grid size. To do dose calculation for every patient, two workstations with Eclipse was selected firstly and dose calculation time was recorded. Then 4, 5, 6, 7 and 8 workstations were separately selected, and dose calculation time was also recorded. Results The calculation time was the shortest when choosing 6 workstations for dose calculation. The calculation time of 7 workstations and 8 workstations was not shortened, but increased slightly. The average computation time of calling 6 workstations was about 19.1 minutes, which was shorter than that of 2 workstations. At the same time, when Mann-Whitney U test was used to conduct comparing analysis on 6 workstations with 2, 4, 5, 7, 8 workstations, the Z score was separately -4.667,-2.634, -1.348, -0.415 and -1.390, and P value was separately 0.000, 0.008, 0.178, 0.678 and 0.165. Conclusion The computation time of calling 6 workstations was shorter than that of 2 and 4 stations, which had statistical difference. The computation time of calling 6 workstations was shorter than that of 5, 7 and 8 stations, but there was no statistical difference. To increase the number of workstations used to calculation call in a LAN, the dose time can be reduced to a certain extent, and the efficiency of tumor radiotherapy plan designing can be improved.关键词
