Journal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.Abstract Background Extending the source‐to‐surface distance (SSD) is an effective approach to cover a large irradiation area in electron beam therapy for large planning target volumes (PTVs). However, the accuracy of dose calculations at extended SSDs has not been fully validated.

Geostandards and Geoanalytical Research, Volume 49, Issue 3, Page 495-533, September 2025.Key Points Synchrotron nano‐imaging is necessary to locate elemental nanophases. Trace metal quantification requires high sensitivity nano‐XRF. Trace metal speciation relies on nano‐XANES using nano‐XRF. This chapter (Nano‐Imaging for Advanced X‐ray Fluorescence and Absorption Spectroscopy Applications) is a contribution to the Geostandards and ...

Application of variance reduction techniques in EGSnrc based Monte-Carlo method
Science and Technology Development Journal, 2019 Introduction: Monte Carlo (MC) is considered to be the most accurate method to calculate dose distribution in radiation therapy. However, the limitation of MC simulations is the long calculation time to reach the desired statistical uncertainty in the dose calculation as well as in clinical practice.
