Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

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

Radiation Safety in Practice: A Cross‐Sectional Study on Radiographers' Knowledge, Awareness and Adherence to Personal Radiation Monitoring Devices in Resource Limited Settings

Journal of Medical Radiation Sciences, EarlyView.
This study examined how well radiographers in five major Namibian state hospitals understand and use Personal Radiation Monitoring Devices (PRMD), a critical tool for occupational safety. While most respondents showed strong knowledge and awareness of PRMDs, many were unaware of their own radiation exposure and rarely reviewed their dose records ...

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

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 ...

3D‐Printed Crosslinked Nanocellulose‐MXene Hydrogels and Aerogels with High Strength and Conductivity

Small, EarlyView.
This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

Transporter‐Associated Therapeutic Efficacy of an SMVT‐Targeted Boron Carrier in Boron Neutron Capture Therapy

Cancer Science, EarlyView.
The transporter‐associated BNCT strategy using BBCIP with or without BPA according to tumor transporter characteristics. BPA showed greater efficacy in LAT1‐dominant F98 glioma, whereas BBCIP was more effective in SMVT‐high CRL1666 tumors, suggesting the potential utility of transporter‐based boron carrier selection in BNCT.
