Shinobu Kumagai, Medical Physicist at Teikyo University Hospital, Tokyo Metropolitan Police Hospital and Juntendo University Nerima Hospital, shared on LinkedIn:
“JASTRO 2026, Day 3, Improving Brachytherapy Workflows with Elekta Studio.
Today was the third and final day of JASTRO 2026. I had four activities scheduled today.
Three were poster presentations covering:
- The accuracy of SGRT (C-RAD) for radiotherapy performed with patients wearing clothing.
- The feasibility of using IQM for initial patient-specific QA (PSQA) screening.
- AI task allocation in medical physicists’ clinical workflows.My fourth activity was a live presentation at the Elekta booth, where I shared our clinical experience with Elekta Studio and its impact on brachytherapy workflows.
Since introducing Elekta Studio at our institution, we have achieved substantial reductions in the time required for several steps of our brachytherapy workflow.

It was a valuable opportunity to share these practical experiences with a large audience.
I believe this system has the potential to address some of the operational challenges faced by brachytherapy centers.
In particular, reducing the workload for clinical staff while also reducing the burden on patients is an important goal. This was an excellent way to conclude three days at JASTRO 2026.”
