Impact of Monaco sequencing parameters on monitor units, plan quality, and optimization time for Elekta Unity liver SBRT plans

Bryan C. Bates, Guanghua Yan, Amanda Schwarz

Abstract Background Magnetic resonance‐guided radiation therapy (MRgRT) using the Elekta Unity MR‐linac offers significant advantages for liver stereotactic body radiation therapy (SBRT). However, the Unity is limited by a low dose rate and the lack of volumetric‐modulated arc therapy (VMAT), resulting in …

Patient setup variation on Elekta Unity and its impact on adaptive planning

Erika Kollitz, Sheng‐Hsuan Sun, Kathryn Hitchcock, Alexandra De Leo et autres

PURPOSE: The unique design of the MR-linac may restrict the use of effective immobilization devices, resulting in significant patient setup variations (PSVs). The purpose of this study is to analyze the PSVs on the Elekta Unity system and investigate their impact on …

MR‐linac MLC positioning QA by digitally stitching dual double‐exposed films

Sheng‐Hsuan Sun, Erika Kollitz, Wenchih Tseng, Amanda Schwarz et autres

PURPOSE: The picket fence (PF) test is highly recommended for multi-leaf collimator (MLC) quality assurance. However, since the electronic portal imaging device (EPID) on the Elekta Unity only covers a small area, it is not feasible to perform the PF test for …
