Impact of intracellular radionuclide distribution in a Monte Carlo biophysical 3D multi‐cellular model for targeted alpha therapy

Medical Physics, Volume 52, Issue 7, July 2025.
Abstract Background To understand and predict the therapeutic efficacy of targeted alpha therapy (TAT), nano‐ and microdosimetry are needed to consider the very heterogeneous dose deposition at cellular and subcellular levels. Purpose The objective of this study is to theoretically evaluate the importance of cell internalization of alpha‐emitters on ...

Entry skin dose reduction in an inline MRI‐linac using an electron contamination deflector coupled with a helium volume

Medical Physics, Volume 52, Issue 7, July 2025.
Abstract Background A unique feature of inline MRI‐linac prototype systems is the changes to entry surface or skin doses. For the high field (1 T) Australian MRI‐linac prototype, a strong surface dose increase is observed. This is a by‐product of secondary electron contamination being focused down the MRI bore due to the magnetic field being parallel ...

Characterization of a shielded beam current transformer for ultra‐high dose rate (FLASH) electron beam monitoring and dose reporting

Medical Physics, Volume 52, Issue 7, July 2025.
Abstract Background Real‐time beam monitoring and accurate dose reporting is challenging in ultra‐high dose rate (UHDR) electron beams. Although beam current transformers (BCTs) can effectively track parameters such as pulse width (PW) and repetition frequency for UHDR electron beams, recent work has highlighted their sensitivity to electric fields ...

Design, fabrication, commissioning, and dosimetric verification of a GRID collimator for proton SFRT on a compact proton therapy machine

Medical Physics, Volume 52, Issue 7, July 2025.
Abstract Background Proton GRID radiotherapy (RT) is an extension of photon spatially fractionated radiation therapy (SFRT) techniques for bulky invasive tumors. It has been hypothesized that GRID RT improves the therapeutic ratio by minimizing normal tissue toxicities associated with treating bulky volumes while inducing abscopal radiobiologic effects.
