3-D dosimetry readout techniques
(IOP PUBLISHING LTD, 2019-01-01)
A method to verify sections of arc during intrafraction portal dosimetry for prostate VMAT.
(2019-10-16)
This study investigates the use of a running sum of images during segment-resolved intrafraction portal dosimetry for volumetric modulated arc therapy (VMAT), so as to alert the operator to an error before it becomes ...
Calculation of absorbed dose in radiotherapy by solution of the linear Boltzmann transport equations.
(2019-01-10)
Over the last decade, dose calculations which solve the linear Boltzmann transport equations have been introduced into clinical practice and are now in widespread use. However, knowledge in the radiotherapy community ...
Tumor to cervical spinal cord standardized uptake ratio (SUR) improves the reproducibility of <sup>18</sup>F-FDG-PET based tumor segmentation in head and neck squamous cell carcinoma in a multicenter setting.
(2019-01)
Background In quantitative FDG-PET data analysis, normalization of the standardized uptake value (SUV) with an internal image-derived standard improves its reproducibility. In this study, the cervical spinal cord is proposed ...
Metastasis-directed Therapy in Treating Nodal Oligorecurrent Prostate Cancer: A Multi-institutional Analysis Comparing the Outcome and Toxicity of Stereotactic Body Radiotherapy and Elective Nodal Radiotherapy.
(2019-12)
Background Stereotactic body radiotherapy (SBRT) and elective nodal radiotherapy (ENRT) are being investigated as metastasis-directed treatments in oligorecurrent prostate cancer (PC); however, comparative data are still ...
Novel concepts for automated segmentation to facilitate MRI-guided radiotherapy in head and neck cancer
(Institute of Cancer Research (University Of London), 2019-09-30)
The dramatic increase of magnetic resonance imaging (MRI) in daily treatment planning and response assessment of radiotherapy (RT) requires the development of reliable auto-segmentation algorithms for organs-at-risk (OARs) ...
Quantitative photoacoustic imaging study of tumours in vivo: Baseline variations in quantitative measurements.
(ELSEVIER GMBH, 2019-03-01)
Photoacoustic imaging (PAI) provides information on haemoglobin levels and blood oxygenation (sO2). To facilitate assessment of the variability in sO2 and haemoglobin in tumours, for example in response to therapies, the ...
Circulating Metabolic Biomarkers of Screen-Detected Prostate Cancer in the ProtecT Study.
(AMER ASSOC CANCER RESEARCH, 2019-01-01)
BACKGROUND: Whether associations between circulating metabolites and prostate cancer are causal is unknown. We report on the largest study of metabolites and prostate cancer (2,291 cases and 2,661 controls) and appraise ...
Radiotherapy plus cisplatin or cetuximab in low-risk human papillomavirus-positive oropharyngeal cancer (De-ESCALaTE HPV): an open-label randomised controlled phase 3 trial.
(ELSEVIER SCIENCE INC, 2019-01-05)
BACKGROUND: The incidence of human papillomavirus (HPV)-positive oropharyngeal cancer, a disease affecting younger patients, is rapidly increasing. Cetuximab, an epidermal growth factor receptor inhibitor, has been proposed ...
