The RABBIT risk-based approach to clinical implementation of new technology: SRS as a case study

Anna Ralston; Peter Graham; Joel Poder dkk.

Technical Innovations & Patient Support in Radiation Oncology, Vol. 14 · 2020 · Inggris · DOAJ Scopus

Radiation oncology technology continues to evolve rapidly, resulting in advanced versions frequently being brought to market. Before a new product is used standard tests are carried out to reduce the risks associated with failure of the equipment to comply with well-established technical…

A review of whole gland prostate brachytherapy with focal dose escalation to intra-prostatic lesions: Clinical efficacy and technical aspects

Joel Poder; Peter Hoskin; Hayley Reynolds dkk.

Physics and Imaging in Radiation Oncology, Vol. 32 · 2024 · Inggris · DOAJ Scopus

Focal boost to intra-prostatic lesions (IPLs) in radiotherapy could enhance treatment efficacy. Brachytherapy (BT), delivering highly conformal dose with sharp dose gradients emerges as a potentially optimal approach for precise dose escalation to IPLs. This study aims to consolidate clinical and…

Mid-ventilation PTV approach for stereotactic ablative body radiotherapy in stage I non-small-cell lung carcinoma: Implementation of a single-system workflow

Kendell Shields-Dowton; Joel Poder; Johnson Yuen dkk.

Technical Innovations & Patient Support in Radiation Oncology, Vol. 37 · 2026 · Inggris · DOAJ Scopus

Introduction: The Mid-Ventilation (MidV) approach is an alternative to internal target volume (ITV) for generating a planning target volume (PTV) in lung stereotactic ablative radiotherapy (SABR). It has been shown to reduce PTV and volume of normal lung tissue irradiated, whilst maintaining high…

Characterization of the First Prototype of an Angular Independent Silicon Diode Array for Quality Assurance in Stereotactic Radiosurgery

Aishah Bashiri; Sean Hood; Jessie Posar dkk.

Applied Sciences, Vol. 14 No. 13 · 2024 · Inggris · DOAJ Scopus

Quality assurance (QA) ensures the accurate and safe delivery of radiation treatment. However, there are several challenges for advanced radiotherapy techniques, such as stereotactic radiosurgery (SRS), where substantial doses of radiation with multi-directional beams and variable dose rates are…

Preliminary Characterization of an Active CMOS Pad Detector for Tracking and Dosimetry in HDR Brachytherapy

Thi Ngoc Hang Bui; Matthew Large; Joel Poder dkk.

Sensors, Vol. 24 No. 2 · 2024 · Inggris · DOAJ Scopus

We assessed the accuracy of a prototype radiation detector with a built in CMOS amplifier for use in dosimetry for high dose rate brachytherapy. The detectors were fabricated on two substrates of epitaxial high resistivity silicon. The radiation detection performance of prototypes has been tested…

Establishing Linearity of the MOSkin Detector for Ultra-High Dose-per-Pulse, Very-High-Energy Electron Radiotherapy Using Dose-Rate-Corrected EBT-XD Film

James Cayley; Elette Engels; Tessa Charles dkk.

Applied Sciences, Vol. 15 No. 14 · 2025 · Inggris · DOAJ Scopus

Very-high-energy electrons, coupled with ultra-high dose rates, are being explored for their potential use in radiotherapy to treat deep-seated tumours. The dose per pulse needed to achieve ultra-high dose rates far exceeds the limit of current medical linear accelerator capabilities. A high dose…
