Medical Physics, Volume 52, Issue 8, August 2025.Abstract Background Minibeam radiotherapy has demonstrated its potential to reduce normal tissue toxicity while maintaining tumor control. However, the underlying mechanisms behind this phenomenon remain unknown. Recent theoretical studies suggest a dose surrogate by diffusion of H2O2${\rm H}_2{\rm O}_2$ into the valley regions.

Development of a linear array for intracavitary in vivo dosimetry during external beam radiotherapy and brachytherapy. [PDF]
, 2003 We present the details of a new linear array dosimeter consisting of a chain of semiconductors mounted on an ultra-thin (50 μm thick) flexible substrate and housed in an intracavitary catheter. The semiconductors, manufactured by NMRC Cork, have not been

Converging lens radiotherapy (CLRT) employing kilovoltage x‐ray source: Treatment planning study
Medical Physics, Volume 52, Issue 8, August 2025.Abstract BackgroundConverging lens radiotherapy (CLRT) is a novel radiotherapy modality employing a lens which produces a nearly monoenergetic x‐ray beam at 60 keV to focus radiation on deep‐seated tumors, enabling highly precise dose delivery. PurposeThis study represents the first comparison of CLRT treatment plan quality to conventional intensity ...

Radiation induced vaporization of exoskeletal droplets as potential x‐ray acoustic contrast agents
Medical Physics, Volume 52, Issue 8, August 2025.Abstract Background In vivo dosimetry is a crucial component of ensuring accurate and safe radiation therapy (RT) delivery, but many existing techniques face challenges such as low signal‐to‐noise ratio (SNR), which can limit their clinical applicability.
