Focused ultrasound transducer spatial peak intensity estimation: a comparison of methods.
(2018-03-07)
Characterisation of the spatial peak intensity at the focus of high intensity focused ultrasound transducers is difficult because of the risk of damage to hydrophone sensors at the high focal pressures generated. Hill et ...
The Feasibility of Thermal Imaging as a Future Portal Imaging Device for Therapeutic Ultrasound.
(ELSEVIER SCIENCE INC, 2016-08-01)
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 ...
Quantitative photoacoustic imaging study of tumours in vivo: Baseline variations in quantitative measurements.
(ELSEVIER GMBH, 2019-03-01)
Photoacoustic imaging (PAI) provides information on haemoglobin levels and blood oxygenation (sO2). To facilitate assessment of the variability in sO2 and haemoglobin in tumours, for example in response to therapies, the ...
Maternal and fetal cardiometabolic recovery following ultrasound-guided high-intensity focused ultrasound placental vascular occlusion.
(ROYAL SOC, 2019-05-31)
High-intensity focused ultrasound (HIFU) is a non-invasive method of selective placental vascular occlusion, providing a potential therapy for conditions such as twin-twin transfusion syndrome. In order to translate this ...
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.
(ELSEVIER SCIENCE INC, 2019-02-21)
PURPOSE: 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 ...
'Relationship between thermal dose and cell death for "rapid" ablative and "slow" hyperthermic heating'.
(TAYLOR & FRANCIS LTD, 2019-01-01)
AIM: Thermal isoeffective dose (TID) has not been convincingly validated for application to predict biological effects from rapid thermal ablation (e.g., using >55 °C). This study compares the classical method of quantifying ...
Value of diffusion-weighted imaging for monitoring tissue change during magnetic resonance-guided high-intensity focused ultrasound therapy in bone applications: an ex-vivo study.
(SPRINGERNATURE, 2018-05-10)
BACKGROUND: Magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU) can palliate metastatic bone pain by periosteal neurolysis. We investigated the value of diffusion-weighted imaging (DWI) for monitoring ...
Combining radiation with hyperthermia: a multiscale model informed by in vitro experiments.
(ROYAL SOC, 2018-01-01)
Combined radiotherapy and hyperthermia offer great potential for the successful treatment of radio-resistant tumours through thermo-radiosensitization. Tumour response heterogeneity, due to intrinsic, or micro-environmentally ...
Focused ultrasound transducer spatial peak intensity estimation: a comparison of methods.
(IOP PUBLISHING LTD, 2018-03-07)
Characterisation of the spatial peak intensity at the focus of high intensity focused ultrasound transducers is difficult because of the risk of damage to hydrophone sensors at the high focal pressures generated. Hill et ...
Focused Ultrasound-Mediated Hyperthermia in Vitro: An Experimental Arrangement for Treating Cells under Tissue-Mimicking Conditions.
(ELSEVIER SCIENCE INC, 2019-12-01)
An experimental arrangement that allows in vitro exposure of cells to focused ultrasound-mediated hyperthermia (43°C-55°C) in a tissue-mimicking phantom with biological, acoustic and thermal properties comparable to those ...
