Application programming interface guided QA plan generation and analysis automation

Purpose Linear accelerator quality assurance (QA) in radiation therapy is a time consuming but fundamental part of ensuring the performance characteristics delivering machines. The goal this work to develop an automated and standardized QA plan generation analysis system Oncology Information System (OIS) streamline process. Methods Automating process includes two software components: AutoQA Builder generate daily, monthly, quarterly, miscellaneous periodic linear plans within Treatment Planning (TPS) Analysis analyze images collected on Electronic Portal Imaging Device (EPID) allowing for rapid acquired images. To verify results analysis, were compared current standard assessment jaw junction, light-radiation coincidence, picket fence, volumetric modulated arc (VMAT) across three linacs over 6-month period. Results application has been utilized clinically 322 times create patients, construct phantom images, deploy common tests multiple institutions, accelerators, physicists. Comparing with our institutional mean difference ratio intensity values field-matched junction ball-bearing position detection was 0.012 ± 0.053 (P = 0.159) 0.011 0.224 mm 0.355), respectively. VMAT resulted maximum percentage 0.3%. Conclusion creation using APIs can be immediate benefit efficiency standardization. done without following tedious procedures through API assistance, performed inside clinical OIS fashion.
