Develop a novel non‐coplanar trajectory optimization algorithm for an efficient 4pi spot‐scanning proton Arc (SPArc‐4pi) treatment delivery

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background The degree of freedom has been recognized as a key factor in particle beam therapy, such as improving the dose conformity and linear energy transfer distributions. Therefore, proton arc therapy has drawn significant interest in the Society of Radiation Oncology as a potentially efficient and optimal treatment option for cancer ...

A coarse‐to‐fine framework combining deep learning and Monte Carlo for BNCT patient position optimization toward inverse planning

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Boron Neutron Capture Therapy (BNCT) utilizes high linear energy transfer (LET) charged particles from the 10B(n,α)7Li reaction to selectively destroy tumor cells. Unlike conventional radiation therapy, BNCT facilities rely on fixed beam ports, making patient positioning critical in treatment planning.

Experimental activation assessment of open‐type yoke in a PET cyclotron by non‐destructive/destructive γ‐ray measurement approaches

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background During decommissioning of positron emission tomography (PET) cyclotron facilities, metallic components—including the iron yoke—are typically classified as radioactive waste, incurring substantial disposal costs. In contrast to concrete, standardized decommissioning procedures for metallic components have not yet been established ...

From Skull Density Ratio‐based eligibility to efficiency‐informed planning: Predictive modeling of thermal response in MR‐guided focused ultrasound

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Transcranial MR‐guided focused ultrasound (MRgFUS) enables incisionless thermoablation of deep brain targets and has become an established modality in functional neurosurgery. Treatment efficiency is strongly influenced by skull‐mediated ultrasound attenuation.

Roadmap for the implementation of particle minibeam therapy

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Particle minibeam therapy (PMBT) has emerged as an advanced modality within spatially fractionated radiation therapy, using the physical properties of protons, ions, and electrons to achieve superior normal tissue sparing whilst preserving spatial dose distribution at depths that are unachievable in conventional kV or MV X‐rays.
