A novel amplitude binning strategy to handle irregular breathing during 4DMRI acquisition: improved imaging for radiotherapy purposes.
(BMC, 2019-05-14)
BACKGROUND: For radiotherapy of abdominal cancer, four-dimensional magnetic resonance imaging (4DMRI) is desirable for tumor definition and the assessment of tumor and organ motion. However, irregular breathing gives rise ...
Low-cost Kinect Version 2 imaging system for breath hold monitoring and gating: Proof of concept study for breast cancer VMAT radiotherapy.
(WILEY, 2018-05-01)
Voluntary inspiration breath hold (VIBH) for left breast cancer patients has been shown to be a safe and effective method of reducing radiation dose to the heart. Currently, VIBH protocol compliance is monitored visually. ...
Towards real-time photon Monte Carlo dose calculation in the cloud.
(IOP Publishing Ltd, 2017-06-07)
Near real-time application of Monte Carlo (MC) dose calculation in clinic and research is hindered by the long computational runtimes of established software. Currently, fast MC software solutions are available utilising ...
Lung volume reproducibility under ABC control and self-sustained breath-holding.
(WILEY, 2017-03-01)
An Active Breathing Coordinator (ABC) can be employed to induce breath-holds during CT imaging and radiotherapy of lung, breast and liver cancer, and recently during lung cancer MRI. The apparatus measures and controls ...
T2-Weighted 4D Magnetic Resonance Imaging for Application in Magnetic Resonance-Guided Radiotherapy Treatment Planning.
(LIPPINCOTT WILLIAMS & WILKINS, 2017-10-01)
OBJECTIVES: The aim of this study was to develop and verify a method to obtain good temporal resolution T2-weighted 4-dimensional (4D-T2w) magnetic resonance imaging (MRI) by using motion information from T1-weighted 4D ...
Standardisation of Target Volume Delineation for Carotid-sparing Intensity-modulated Radiotherapy in Early Glottis Cancer.
(ELSEVIER SCIENCE LONDON, 2017-01-01)
AIMS: Recently, carotid-sparing intensity-modulated radiotherapy (IMRT) for early laryngeal glottis (T1/T2N0M0) cancer has generated interest in the hope of avoiding long-term carotid toxicity, as well as concerns relating ...
Real-time 4D dose reconstruction for tracked dynamic MLC deliveries for lung SBRT.
(WILEY, 2016-11-01)
PURPOSE: This study provides a proof of concept for real-time 4D dose reconstruction for lung stereotactic body radiation therapy (SBRT) with multileaf collimator (MLC) tracking and assesses the impact of tumor tracking ...
A kernel-based dose calculation algorithm for kV photon beams with explicit handling of energy and material dependencies.
(BRITISH INST RADIOLOGY, 2017-01-01)
OBJECTIVE: Mimicking state-of-the-art patient radiotherapy with high-precision irradiators for small animals is expected to advance the understanding of dose-effect relationships and radiobiology in general. We work on the ...
Phase I/II trials of 186Re-HEDP in metastatic castration-resistant prostate cancer: post-hoc analysis of the impact of administered activity and dosimetry on survival.
(SPRINGER, 2017-04-01)
PURPOSE: To investigate the role of patient-specific dosimetry as a predictive marker of survival and as a potential tool for individualised molecular radiotherapy treatment planning of bone metastases from castration-resistant ...
Real-time auto-adaptive margin generation for MLC-tracked radiotherapy.
(IOP PUBLISHING LTD, 2017-01-07)
In radiotherapy, abdominal and thoracic sites are candidates for performing motion tracking. With real-time control it is possible to adjust the multileaf collimator (MLC) position to the target position. However, positions ...
