July 16, 2025 – Elekta’s Online Magazine – Secondary Dose Check accelerates 3D adaptive MR-guided RT workflow at Australian hospital
After a year serving as an Elekta pilot adopter for the company’s ThinkQA Secondary Dose Check (SDC), physicists at Townsville University Hospital (TUH, Queensland, Australia) have spent the last seven months using ThinkQA SDC for quality assurance (QA) checks of their Elekta Unity MR-Linac adaptive treatment plans for prostate/nodes SBRT cases. The web-based ThinkQA SDC solution has enabled them – in less than two minutes – to obtain, in the gamma analysis, at least 95 percent agreement between their Monaco treatment planning system (TPS) plans and ThinkQA SDC dose calculations. For Unity cases – in which the treatment plan QA is done with the patient in the treatment position – the speed and accuracy of ThinkQA SDC has been a major benefit.
“While your main focus is obtaining the gamma analysis for the target, we are also getting it for the regions away from the target where the OARs reside,” Dr. Baines explains. “With ThinkQA you get a really comprehensive picture of dose levels and their gamma analysis values.”
“By the time the radiation oncologist is ready to accept the plan, ThinkQA has confirmed the integrity of the plan, we reimage the patient with MRI to make sure that the patient hasn’t moved since the last MRI, and then treatment proceeds. ThinkQA provides a truly a parallel workflow – no time is wasted.”
