摘要
Abstract
[Objective]To compare and analyze the errors between computed tomography-treatment planning system (CTTPS) and electronic portal imaging device (EPID) in first treatment setup of head and neck tumors, to discuss the accuracy of the two methods in position verification, to further improve the quality assurance and quality control of the primary radiotherapy units. [Methods]Thirty-seven head and neck cancer patients who accepted radiotherapy were selected from May 2015 to December 2016, CT-TPS and EPID were used for position verification in setup of first treatment, errors in lateral-X, longitudinal-Y and vertical-Z direction of two methods were compared.[Results]Linear errors in X, Y, Z directions between CT-TPS and EPID were slightly different, P values were all greater than 0.05, no significant difference existed.[Conclusion]Two position verification methods of CT-TPS and EPID can provide accurate numerical errors value and meet clinical requirements. For primary radiotherapy units, two methods can be used in combination or alone, CT-TPS position verification can replace EPID when EPID fails.关键词
