Journal of Medical Radiation Sciences, EarlyView.This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

Technical Innovations & Patient Support in Radiation Oncology, 2017 Introduction: Automated target volumes adaptation could be useful in H&N replanning, but its dosimetric impact has not been analyzed. Primary aim of this investigation is dose coverage assessment in fully automated and edited PTV adaptation settings ...

Journal of Medical Radiation Sciences, EarlyView.This review highlights the role of functional imaging in sparing cognitive brain regions during glioma radiotherapy. It shows promising dose reduction without compromising target coverage, but evidence remains limited, requiring standardisation and prospective validation.

PTV-CMA blind equalization and interference suppression
, 2000 The problem of blindly equalizing a digital communication signal distorted by a linear time-invariant channel, and contaminated by severe co-channel or adjacent-channel digital interference, is considered in this paper.

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Advances in digital holographic micro-PTV for analyzing microscale flows
, 2018 The accurate three-dimensional (3D) velocity field measurement technique has been receiving large attention in the study of microfluidics. DHM-PTV technique was developed by combining the digital holographic microscopy and particle tracking velocimetry ...

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...
