In‐house development of CT‐based 3D‐printed head & neck phantom for Radiotherapy applications

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Anthropomorphic phantoms are widely used in Radiotherapy for quality assurance (QA), treatment verification and dosimetric validation purposes. However, commercially available anthropomorphic phantoms are expensive and offers limited customization, restricting their broader clinical use.

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, Volume 73, Issue 2, Page 156-163, June 2026.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Integrating measurement and simulation for evaluation of patient‐specific whole‐body dosimetry in clinical BNCT

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Boron neutron capture therapy (BNCT) is a treatment modality that utilises high intensity neutron beam in combination with a boron drug to target cancer cells at the cellular level. Despite decades of research in this field, there are very few reports on out‐of‐field patient dose of BNCT.

Pulse‐to‐pulse analysis of ultra‐high dose per pulse electron beams using beam current transformers

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Ultra‐high dose per pulse (UHDPP) beams have shown to be promising for clinical applications due to their healthy tissue sparing potential. In this radiotherapy modality, a limited number of pulses (often < 25) can deliver the prescribed dose, making pulse‐to‐pulse beam stability essential for accurate dose delivery. In this context,
