Automatic reconstruction of the delivered dose of the day using MR-linac treatment log files and online MR imaging.
(ELSEVIER IRELAND LTD, 2020-01-10)
BACKGROUND AND PURPOSE: Anatomical changes during external beam radiotherapy prevent the accurate delivery of the intended dose distribution. Resolving the delivered dose, which is currently unknown, is crucial to link ...
Dosimetric accuracy of delivering SBRT using dynamic arcs on Cyberknife.
(WILEY, 2020-04-01)
PURPOSE: Several studies have demonstrated potential improvements in treatment time through the use of dynamic arcs for delivery of stereotactic body radiation therapy (SBRT) on Cyberknife. However, the delivery system has ...
Feasibility of magnetic resonance guided radiotherapy for the treatment of bladder cancer.
(ELSEVIER IRELAND LTD, 2020-11-01)
Whole bladder magnetic resonance image-guided radiotherapy using the 1.5 Telsa MR-linac is feasible. Full online adaptive planning workflow based on the anatomy seen at each fraction was performed. This was delivered within ...
Edge effects in 3D dosimetry: characterisation and correction of the non-uniform dose response of PRESAGE®.
(IOP PUBLISHING LTD, 2020-05-04)
Previous work has shown that PRESAGE® can be used successfully to perform 3D dosimetric measurements of complex radiotherapy treatments. However, measurements near the sample edges are known to be difficult to achieve. ...
Daily adaptive radiotherapy for patients with prostate cancer using a high field MR-linac: Initial clinical experiences and assessment of delivered doses compared to a C-arm linac.
(ELSEVIER IRELAND LTD, 2020-07-01)
INTRODUCTION: MR-guided adapted radiotherapy (MRgART) using a high field MR-linac has recently become available. We report the estimated delivered fractional dose of the first five prostate cancer patients treated at our ...
A treatment planning study of combined carbon ion-beam plus photon intensity-modulated radiotherapy.
(ELSEVIER, 2020-07-01)
BACKGROUND AND PURPOSE: Combined photon intensity-modulated radiotherapy (IMRT) and sequential dose-escalated carbon ion beam therapy (IBT) is a technically advanced treatment option for head and neck malignancies. We ...
Consistent and invertible deformation vector fields for a breathing anthropomorphic phantom: a post-processing framework for the XCAT phantom.
(IOP PUBLISHING LTD, 2020-08-13)
Breathing motion is challenging for radiotherapy planning and delivery. This requires advanced four-dimensional (4D) imaging and motion mitigation strategies and associated validation tools with known deformations. Numerical ...
