Pulse‐to‐pulse analysis of ultra‐high dose per pulse electron beams using beam current transformers

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Ultra‐high dose per pulse (UHDPP) beams have shown to be promising for clinical applications due to their healthy tissue sparing potential. In this radiotherapy modality, a limited number of pulses (often < 25) can deliver the prescribed dose, making pulse‐to‐pulse beam stability essential for accurate dose delivery. In this context,

Credentialing of small‐field dosimetry for the lung SBRT in Japan Clinical Oncology Group clinical trial

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Small‐field dosimetry plays a pivotal role in stereotactic body radiation therapy (SBRT), where high‐precision dose delivery is essential. In multi‐institutional clinical trials, quality assurance (QA) becomes increasingly critical due to the variability in linear accelerator (linac) output calibration and treatment planning system (
