MRI-based Assessment of 3D Intrafractional Motion of Head and Neck Cancer for Radiation Therapy.
(ELSEVIER SCIENCE INC, 2018-02-01)PURPOSE: To determine the 3-dimensional (3D) intrafractional motion of head and neck squamous cell carcinoma (HNSCC). METHODS AND MATERIALS: Dynamic contrast-enhanced magnetic resonance images from 56 patients with HNSCC ... -
MRI-guided adaptive radiotherapy for prostate cancer: When do we need to account for intra-fraction motion?
(ELSEVIER IRELAND LTD, 2022-11-01)A shift of the daily plan can mitigate target position changes that occur between daily MR acquisition and treatment for MR-linac radiotherapy, but increases the session time. We demonstrated that our workflow strategy and ... -
MRI-guided lung SBRT: Present and future developments.
(ELSEVIER SCI LTD, 2017-12-01)Stereotactic body radiotherapy (SBRT) is rapidly becoming an alternative to surgery for the treatment of early-stage non-small cell lung cancer patients. Lung SBRT is administered in a hypo-fractionated, conformal manner, ... -
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 ... -
Multi-Channel Optical Coherence Elastography Using Relative and Absolute Shear-Wave Time of Flight.
(PUBLIC LIBRARY SCIENCE, 2017-01-20)Elastography, the imaging of elastic properties of soft tissues, is well developed for macroscopic clinical imaging of soft tissues and can provide useful information about various pathological processes which is complementary ... -
