Monte Carlo simulations are widely used to derive effective dose conversion factors (k-factors) for CT; however, acquisition parameters such as helical pitch and tube starting angle are often randomly selected. The impact of thes...

Inorganic scintillating detectors offer high-precision and high spatiotemporal resolution dosimetry for small-field radiotherapy applications such as SRS, SBRT, and SFRT. This study examines the impact of detector materials and v...

To determine whether adjusting MLC blocking of the left anterior descending artery (LAD) in left breast radiotherapy plans can reduce heart and LAD doses and improve plan robustness while maintaining desired target coverage.

This study assessed the impact of machine-specific delivery sequence in quantifying interplay effects for lung stereotactic body radiotherapy (SBRT) between two proton therapy modalities, intensity-modulated proton therapy (IMPT)...

Respiratory motion during proton therapy introduces uncertainties that can lead to dose inhomogeneities, primarily due to the interplay between tumor motion and spot-scanning beam delivery. Understanding and predicting this effec...

To identify key factors influencing proton beam delivery accuracy with a Mevion Hyperscanning system equipped with Adaptive Aperture, and to address parameters contributing to patient-specific quality assurance (PSQA) failures th...

Proton therapy treatments deliver a prescribed absorbed dose to the patient. This work investigates both energy deposition and the temporal evolution of water radiolysis products at micrometric scales, combining a multi-scale app...

To evaluate the impact of Monaco sequencing parameters on monitor units per fraction (MU/Fx), plan quality, and plan optimization time for liver SBRT treated on the Elekta Unity MR-linac.

To compare HyperSight imaging systems between O-ring (Halcyon) and C-arm (TrueBeam) machine, with specific emphasis on the impact of motion in resulting dose calculation.

Eclipse v18 introduces an enhanced leaf model (ELM) for multileaf collimator (MLC) configuration. The model requires dosimetric measurements acquired with MLC-shaped fields and is therefore sensitive to leaf condition. Although l...

To evaluate how varying the noise-suppression level and reducing the imaging exposure affects contrast-detail performance and other image quality metrics in image-guided radiation therapy.

To quantify the impact of proton dose calculation methodology, including nuclear halo contributions, on secondary cancer risk for near-field organs following proton craniospinal irradiation.

To quantify the effect of interfractional anatomic variation on dose-averaged linear energy transfer (LETd) in head-and-neck intensity-modulated proton therapy (IMPT), and to determine whether daily adaptive proton therapy (APT)...

Opportunistic coronary artery calcium (CAC) assessment from lung cancer screening (LCS) CT can broaden cardiovascular risk stratification, but cardiac motion and acquisition settings may impact the calcium score. This study quant...

Weisskoff analysis assesses temporal stability of echo-planar imaging (EPI) in functional MRI (fMRI) by comparing how the temporal coefficient of variation (CoV) scales with ROI size relative to uncorrelated noise (e.g. ideal sca...

To map the saturation behaviour of quenching in multiple CeTb-doped optical fibres, with different levels of X-rays pre-irradiation, under proton irradiation.

To quantify the effects of respiratory motion and target size on internal target volume (ITV) geometric accuracy and Hounsfield Units (HU) stability in fast (6 s) and slow (60 s) thoracic HyperSight CBCT acquisitions.

Small metallic objects such as titanium and tantalum surgical clips are frequently present in clinical treatment planning images. Because these objects produce streak artifacts in planning CT images and may lie within the beam pa...

A single institution clinical trial evaluated the efficacy of structured patient education and individualized CBCT-based visual feedback on the consistency and magnitude of bladder volume relative to the planning simulation basel...

Tin filtration has shown improved dose efficiencies in conventional CT for renal stone imaging. Photon-counting CT (PCCT) enables virtual monoenergetic image (VMI) reconstructions that can enhance stone conspicuity. This study ev...

To investigate the effect of tumour location and incidental radiation dose delivered to the internal mammary lymph nodes (IMLNs) in breast radiotherapy (RT) on breast cancer-specific mortality (BCSM).

Definitive radiotherapy for oropharyngeal cancer (OPC) requires adequate PTV coverage, but the optimal degree of target coverage is unknown. Some protocols require a PTVD95≥95% whereas others require PTVD95≥100% of prescription d...

This project aimed to characterize a shielding technique for total skin electron therapy (TSET) patients with implanted cardiac devices (ICDs). Goals of the work included quantifying shielding effectiveness by quantifying and min...

To validate and assess the performance of an AI-assisted tool, CorneliUS, for needle reconstruction in high dose rate (HDR) ultrasound-guided prostate brachytherapy in an independent clinical setting.
