Journal of Medical Radiation Sciences, Volume 73, Issue 1, Page 7-18, March 2026.This scoping review examined models estimating long‐term radiation risks from repeated mammography screening. While modelling indicates the risks are low, approaches vary by protocol and vendor. Emerging AI tools show promise for improving personalised risk estimation, though further development is needed for cross‐platform compatibility.

Medical Physics, Volume 53, Issue 3, March 2026.Abstract Background Carbon‐ion radiotherapy offers highly precise targeting of tumors while sparing healthy tissue compared to X‐ray therapy. However, this precision comes at the cost of an increased sensitivity of the treatment to range uncertainties, which can arise from anatomical changes of the patient.

Upright and supine particle therapy of lung cancer: A 4D dosimetric comparison
Medical Physics, Volume 53, Issue 3, March 2026.Abstract Background A renewed interest in upright particle therapy is currently driven by the availability of upright positioning and imaging systems. The upright positioning system could enhance fixed beamlines for effective carbon ion treatments in central body regions, with a substantial cost and space advantage.

Clinical and Translational Radiation OncologyBackground and purpose: Hypoxia in tumors significantly contributes to radiation resistance, often leading to poor treatment outcomes. In vitro studies demonstrated that proton irradiation not only exhibits an increased relative biological effectiveness (
