Quality assurance for the clinical implementation of kilovoltage intrafraction monitoring for prostate cancer VMAT.
Published 2014-11-01PURPOSE: Kilovoltage intrafraction monitoring (KIM) is a real-time 3D tumor monitoring system for cancer radiotherapy. KIM uses the commonly available gantry-mounted x-ray imager as input, making this method potentially ...Open AccessArticle -
Quantification of intrafraction prostate motion and its dosimetric effect on VMAT.
Published 2017-06-01Intrafraction prostate motion degrades the accuracy of radiation therapy (RT) delivery. Whilst a number of metrics in the literature have been used to quantify intrafraction prostate motion, it has not been established ...Open AccessArticle -
Quantification of lung tumor rotation with automated landmark extraction using orthogonal cine MRI images.
Published 2015-09-01The quantification of tumor motion in sites affected by respiratory motion is of primary importance to improve treatment accuracy. To account for motion, different studies analyzed the translational component only, without ...Open AccessArticle -
Quantifying the accuracy and precision of a novel real-time 6 degree-of-freedom kilovoltage intrafraction monitoring (KIM) target tracking system.
Published 2017-06-01Target rotation can considerably impact the delivered radiotherapy dose depending on the tumour shape. More accurate tumour pose during radiotherapy treatment can be acquired through tracking in 6 degrees-of-freedom (6 ...Open AccessArticle -
Quantifying the accuracy of the tumor motion and area as a function of acceleration factor for the simulation of the dynamic keyhole magnetic resonance imaging method
Published 2016-05-01PURPOSE: The dynamic keyhole is a new MR image reconstruction method for thoracic and abdominal MR imaging. To date, this method has not been investigated with cancer patient magnetic resonance imaging (MRI) data. The ...Open AccessArticle -
Quantifying the image quality and dose reduction of respiratory triggered 4D cone-beam computed tomography with patient-measured breathing.
Published 2015-12-01Respiratory triggered four dimensional cone-beam computed tomography (RT 4D CBCT) is a novel technique that uses a patient's respiratory signal to drive the image acquisition with the goal of imaging dose reduction without ...Open AccessArticle -
Quantifying the impact of respiratory-gated 4D CT acquisition on thoracic image quality: A digital phantom study.
Published 2015-01-01Purpose: Prospective respiratory-gated 4D CT has been shown to reduce tumor image artifacts by up to 50% compared to conventional 4D CT. However, to date no studies have quantified the impact of gated 4D CT on normal lung ...Open AccessArticle -
Quantifying the reproducibility of lung ventilation images between 4-Dimensional Cone Beam CT and 4-Dimensional CT.
Published 2017-05-01PURPOSE: Computed tomography ventilation imaging derived from four-dimensional cone beam CT (CTVI4DCBCT ) can complement existing 4DCT-based methods (CTVI4DCT ) to track lung function changes over a course of lung cancer ...Open AccessArticle -
Quantitative Spectral Assessment of Intracardiac Electrogram Characteristics Associated with Post Infarct Fibrosis and Ventricular Tachycardia
Published 2018-09-01Background: Post-myocardial infarction (MI) remodeling contributes to increased electrophysiological and structural heterogeneity and arrhythmogenesis. Utilising the post-infarct ovine model our aim was to determine unipolar ...Open AccessDataset -
Radiation oncology during COVID-19: Strategies to avoid compromised care
Published 2020The COVID-19 pandemic will present a range of challenges to radiation oncology departments. Early data suggest that cancer patients carry a higher than average, but still low absolute risk of hospitalization from COVID-19. ...Article -
Radiotherapy beyond cancer: target localization in real-time MRI and treatment planning for cardiac radiosurgery.
Published 2014-12-01PURPOSE: Atrial fibrillation (AFib) is the most common cardiac arrhythmia that affects millions of patients world-wide. AFib is usually treated with minimally invasive, time consuming catheter ablation techniques. While ...Open AccessArticle -
A randomised controlled trial of a code-word enuresis alarm
Published 2016-04-15Objective: To compare a novel code-word alarm with a commercially available wireless alarm for treating enuresis Design: Randomised controlled trial with blinding of study personnel and outcome assessors Setting: A tertiary ...Open AccessArticle -
A randomized controlled trial investigating the effects of a low-glycemic index diet on pregnancy outcomes in gestational diabetes mellitus
Published 2011-11-01OBJECTIVE: The prevalence of gestational diabetes mellitus (GDM) is rising. There is little evidence to demonstrate the effectiveness of one dietary therapy over another. We aimed to investigate the effect of a low-glycemic ...Open AccessArticle -
