MRI-guided prostate adaptive radiotherapy - A systematic review.
(2016-06)
Dose escalated radiotherapy improves outcomes for men with prostate cancer. A plateau for benefit from dose escalation using EBRT may not have been reached for some patients with higher risk disease. The use of increasingly ...
Mean heart dose variation over a course of breath-holding breast cancer radiotherapy.
(2016-11)
Objective The purpose of the work was to estimate the dose received by the heart throughout a course of breath-holding breast radiotherapy.Methods 113 cone-beam CT (CBCT) scans were acquired for 20 patients treated within ...
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 ...
Review of ultrasound image guidance in external beam radiotherapy part II: intra-fraction motion management and novel applications.
(IOP PUBLISHING LTD, 2016-04-21)
Imaging has become an essential tool in modern radiotherapy (RT), being used to plan dose delivery prior to treatment and verify target position before and during treatment. Ultrasound (US) imaging is cost-effective in ...
Prospective Study Delivering Simultaneous Integrated High-dose Tumor Boost (≤70 Gy) With Image Guided Adaptive Radiation Therapy for Radical Treatment of Localized Muscle-Invasive Bladder Cancer.
(ELSEVIER SCIENCE INC, 2016-04-01)
PURPOSE: Image guided adaptive radiation therapy offers individualized solutions to improve target coverage and reduce normal tissue irradiation, allowing the opportunity to increase the radiation tumor dose and spare ...
A multicentre study of the evidence for customized margins in photon breast boost radiotherapy.
(BRITISH INST RADIOLOGY, 2016-01-01)
OBJECTIVE: To determine if subsets of patients may benefit from smaller or larger margins when using laser setup and bony anatomy verification of breast tumour bed (TB) boost radiotherapy (RT). METHODS: Verification imaging ...
The impact of 2D cine MR imaging parameters on automated tumor and organ localization for MR-guided real-time adaptive radiotherapy.
(IOP PUBLISHING LTD, 2018-11-22)
2D cine MR imaging may be utilized to monitor rapidly moving tumors and organs-at-risk for real-time adaptive radiotherapy. This study systematically investigates the impact of geometric imaging parameters on the ability ...
Synthetic 4D-CT of the thorax for treatment plan adaptation on MR-guided radiotherapy systems.
(IOP PUBLISHING LTD, 2019-05-23)
MR-guided radiotherapy treatment planning utilises the high soft-tissue contrast of MRI to reduce uncertainty in delineation of the target and organs at risk. Replacing 4D-CT with MRI-derived synthetic 4D-CT would support ...
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 ...
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 ...
