Comparison of Imaging Changes and Pain Responses in Patients with Intra- or Extraosseous Bone Metastases Treated Palliatively with Magnetic Resonance-Guided High-Intensity-Focused Ultrasound.
(2019-09)<h4>Purpose</h4>This study compared changes in imaging and in pain relief between patients with intraosseous, as opposed to extraosseous bone metastases. Both groups were treated palliatively with magnetic resonance-guided ... -
The Feasibility of Thermal Imaging as a Future Portal Imaging Device for Therapeutic Ultrasound.
(2016-08)This technical note describes a prototype thermally based portal imaging device that allows mapping of energy deposition on the surface of a tissue mimicking material in a focused ultrasound surgery (FUS) beam by using an ... -
MR guided high intensity focused ultrasound (MRgHIFU) for treating recurrent gynaecological tumours: a pilot feasibility study.
(2019-06)<h4>Objective</h4>To assess the feasibility of targeting recurrent gynaecological tumours with MR guided high intensity focused ultrasound (MRgHIFU).<h4>Methods</h4>20 patients with recurrent gynaecological tumours were ... -
Realizing the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.
(2019-06)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 ... -
Super-resolution T2-weighted 4D MRI for image guided radiotherapy.
(2018-12)BACKGROUND AND PURPOSE:The superior soft-tissue contrast of 4D-T2w MRI motivates its use for delineation in radiotherapy treatment planning. We address current limitations of slice-selective implementations, including thick ... -
T2-Weighted 4D Magnetic Resonance Imaging for Application in Magnetic Resonance-Guided Radiotherapy Treatment Planning.
(2017-10)<h4>Objectives</h4>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 ...
