The RefleXion linear accelerator utilizes a 6 MV FFF beam with a binary multi-leaf collimator and a pair of Y- jaws with clinical openings of 1 cm and 2 cm. The machine is equipped with a 16-slice on-board fan-beam CT and an on-...
Proton radiography (pRad) has long been proposed to reduce range uncertainties by providing patient-specific stopping power information. Recent developments in proton therapy delivery, including shoot-through beam techniques and...
To evaluate the dosimetric plan quality metrics and possibility of gantry collisions when utilizing +/- 10° couch kicks in 3 arc VMAT lung SBRT plans. Although it has been shown that couch kicks provide better dosimetry for lung...
To determine if the Accuray Precision dose calculator computes dose to water or dose to tissue for Radixact plans.
Standard dose optimization fails in low-resource settings due to unique patient phenotypes, heterogeneous aging equipment, and absent validation pathways. This work presents a closed-loop digital twin ecosystem that autonomously...
To develop prognostic models integrating delta radiomics from prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA-PET/CT) and dosiomics with clinical variables to predict metastasis-free surv...
To evaluate the ability of synthetic PET images derived from standard-of-care (SOC) 18F-FDG PET/CT images to predict the feasibility of biology-guided radiotherapy (BgRT).
To prospectively validate a prior and constraint-informed deep learning auto-segmentation framework for nasopharyngeal carcinoma (NPC) across three clinical centers, addressing accuracy, efficiency, and anatomical plausibility un...
T1-weighted (T1w) and T2-weighted (T2w) FLAIR MRI provide complementary image contrast for delineating gross tumor volume (GTV) and clinical target volume (CTV) in brain tumor radiotherapy (RT) planning during both MRI simulation...
Accurate segmentation of organs at risk (OARs) is essential for high precision head and neck (H&N) radiotherapy, particularly for small and low contrast anatomical structures. Although nnUNet demonstrates strong overall segmentat...
Access to radiation therapy remains a major challenge in many low‑ and middle‑income countries (LMICs), where limited infrastructure and workforce shortages hinder timely cancer treatment. Moi Teaching and Referral Hospital (MTRH...
Annual water-tank measurements help ensure beam characteristics remain consistent with commissioning baselines. However, the lack of a standardized processing workflow and decentralized data storage makes it difficult to analyze...
Intrafraction motion management is essential to reduce setup uncertainty and prevent dose delivery errors during radiotherapy, particularly for tumors influenced by respiratory motion near the diaphragm. Magnetic resonance guided...
Stereotactic arrhythmia radioablation (STAR) offers a non-invasive treatment option for refractory tachycardia; however, precise dose delivery remains challenging due to the complexity of cardiorespiratory motion. This study eval...
To quantify the impact of a prostate motion model on target robustness under setup and range uncertainty, and to evaluate whether anatomical robust optimization improves robustness while maintaining nominal OAR constraint complia...
Laboratory-based micro-X-ray fluorescence(micro-XRF) offers micrometer-scale spatial profiling of elemental distribution in biological tissues. However, quantitative analysis of thin tissue sections can be influenced by instrumen...
To quantify the accuracy of airway measurement using AirQuant on to-scale airway models.
To quantify Gamma Passing Rate (GPR) volatility in SBRT QA caused by the spatial coincidence of helical diode arrays (10 mm pitch) with high-gradient fields. While 3%/2mm criteria reduce alignment artifacts, more sensitive 3%/1mm...
The purpose of this study was to quantitatively analyze the effect of iodine contrast agent injection on heart volume and target volume positioning in patients with thoracic tumors adjacent to the heart, and to further evaluate h...
Accurate source positioning is essential for dose delivery in high-dose-rate (HDR) gynecologic (GYN) brachytherapy, necessitating routine applicator quality assurance (QA). This study introduces an applicator-specific, 3D-printed...
To quantitatively compare image quality from HyperSight CBCT to dedicated CT Simulation scanners, using a standard image quality phantom and conventional imaging metrics to assess performance differences and their statistical sig...
Accurate auto-contouring is essential for efficient prostate radiotherapy, particularly in image-guided and adaptive workflows, where contour quality influences clinical decision-making. This study quantitatively evaluates Radfor...
