- Very high energy electron radiotherapy and gold nanoparticle radiosensitisation: Quantifying DNA damage enhancement in pBR322 plasmids. [Journal Article]Phys Med. 2026 Oct; 150:107177.PM
- While novel radiotherapy modalities such as VHEE (Very High Energy Electron) and FLASH are being developed as effective potential cancer treatments, exposure of healthy cells to dose during radiotherapy remains a major challenge. Use of high-Z nanoparticles, in particular gold nanoparticles (AuNPs) has been identified as a method of radiosensitisation - increasing the toxicity of ionising radiati…

- Simulation-embedded MLEM reconstruction using SIMIND for quantitative myocardial SPECT. [Journal Article]Phys Med. 2026 Oct; 150:107204.PM
- CONCLUSIONS: Simulation-embedded reconstruction enabled integrated physical modeling within iterative reconstruction and improved the agreement with ideal reference images under controlled phantom-based conditions. These findings supported the technical feasibility and basic validity of acquisition-consistent Monte Carlo-embedded reconstruction for myocardial SPECT and provided a basis for further evaluation under more realistic and clinical conditions.

- Optimization of a β probe for [18]F radio-guided surgery. [Journal Article]Phys Med. 2026 Oct; 150:107183.PM
- CONCLUSIONS: A p-terphenyl scintillator thickness of 0.6 mm offers the best trade-off between β sensitivity and γ rejection for β-guided surgery applications with [[18]F]FDG. This study completes the experimental optimization of the β-probe for low-energy positron emitters and provides a solid basis for future in-vivo validation.

- Introduce the first SPArc optimization algorithm for synchrotron accelerator based proton therapy system. [Journal Article]Phys Med. 2026 Oct; 150:107194.PM
- Spot-scanning Proton Arc (SPArc) has drawn significant interest from the particle therapy community because of its superior target dose conformity, Organs-At-Risk (OARs) sparing, and Linear Energy Transfer (LET) modulation. However, all the existing SPArc optimization algorithms are designed for cyclotron-based proton treatment systems (PTS) instead of synchrotron-based PTS with the Single Energy…

- Enhancing patient safety and procedural quality in radiopharmacy: towards multidisciplinary collaboration between radiopharmacists and medical physicists. [Journal Article]Phys Med. 2026 Oct; 150:107188.PM
- CONCLUSIONS: Radiopharmacy practices in Spain show substantial heterogeneity in instrument verification, QC implementation, and radiation protection culture. Strengthening collaboration between RPhs and MPs, standardising procedures, and reinforcing a robust safety culture are essential to improve quality and safety in routine clinical practice.

- CONCLUSIONS: Clinical variables remained the strongest predictors in this small cohort. Compact multimodal models were feasible and interpretable but did not improve leakage-free internal performance. These findings support nested cross-validation in small high-dimensional radiomics and dosiomics studies.
