Combined Ultrasound and Cone Beam CT Improves Target Segmentation for Image Guided Radiation Therapy in Uterine Cervix Cancer.
(ELSEVIER SCIENCE INC, 2019-07-01)
PURPOSE: Adaptive radiation therapy strategies could account for interfractional uterine motion observed in patients with cervix cancer, but the current cone beam computed tomography (CBCT)-based treatment workflow is ...
MRE11 as a Predictive Biomarker of Outcome After Radiation Therapy in Bladder Cancer.
(ELSEVIER SCIENCE INC, 2019-07-15)
PURPOSE: Organ-confined muscle-invasive bladder cancer is treated with cystectomy or bladder preservation techniques, including radiation therapy. There are currently no biomarkers to inform management decisions and aid ...
Comparison of the dose escalation potential for two hypofractionated radiotherapy regimens for locally advanced pancreatic cancer.
(ELSEVIER IRELAND LTD, 2019-03-08)
OBJECTIVES: To determine the potential for dose escalation to a biological equivalent dose BED10 ≅ 100 Gy in hypofractionated radiotherapy for locally advanced pancreatic cancer (LAPC). MATERIALS AND METHODS: Ten unselected ...
Reduced inter-observer and intra-observer delineation variation in esophageal cancer radiotherapy by use of fiducial markers.
(TAYLOR & FRANCIS LTD, 2019-06-03)
Objective: Delineation variation of esophageal tumors remains a large source of geometric uncertainty. In the present study, we investigated the inter- and intra-observer variation in esophageal gross tumor volume (GTV) ...
MRI commissioning of 1.5T MR-linac systems - a multi-institutional study.
(ELSEVIER IRELAND LTD, 2019-03-01)
BACKGROUND: Magnetic Resonance linear accelerator (MR-linac) systems represent a new type of technology that allows for online MR-guidance for high precision radiotherapy (RT). Currently, the first MR-linac installations ...
'Relationship between thermal dose and cell death for "rapid" ablative and "slow" hyperthermic heating'.
(TAYLOR & FRANCIS LTD, 2019-01-01)
AIM: Thermal isoeffective dose (TID) has not been convincingly validated for application to predict biological effects from rapid thermal ablation (e.g., using >55 °C). This study compares the classical method of quantifying ...
Comparison of prostate delineation on multimodality imaging for MR-guided radiotherapy.
(BRITISH INST RADIOLOGY, 2019-03-01)
OBJECTIVE:: With increasing incorporation of MRI in radiotherapy, we investigate two MRI sequences for prostate delineation in radiographer-led image guidance. METHODS:: Five therapeutic radiographers contoured the prostate ...
Realizing the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.
(BRITISH INST RADIOLOGY, 2019-05-14)
CT-based radiotherapy workflow is limited by poor soft tissue definition in the pelvis and reliance on rigid registration methods. Current image-guided radiotherapy and adaptive radiotherapy models therefore have limited ...
Dosimetry and Gastrointestinal Toxicity Relationships in a Phase II Trial of Pelvic Lymph Node Radiotherapy in Advanced Localised Prostate Cancer.
(ELSEVIER SCIENCE LONDON, 2019-06-01)
AIMS: Pelvic lymph node (PLN) radiotherapy for high-risk prostate cancer is limited by late gastrointestinal toxicity. Application of rectal and bowel constraints may reduce risks of side-effects. We evaluated associations ...
Plane wave versus focused transmissions for contrast enhanced ultrasound imaging: the role of parameter settings and the effects of flow rate on contrast measurements.
(IOP PUBLISHING LTD, 2019-04-23)
Contrast enhanced ultrasound (CEUS) and dynamic contrast enhanced ultrasound (DCE-US) can be used to provide information about the vasculature aiding diagnosis and monitoring of a number of pathologies including cancer. ...
