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 ...
Guidelines for Cleaning Transvaginal Ultrasound Transducers Between Patients.
(2017-05)
The purpose of this article is to provide guidance regarding the cleaning and disinfection of transvaginal ultrasound probes. These recommendations are also applicable to transrectal probes.
Dependence of inertial cavitation induced by high intensity focused ultrasound on transducer F-number and nonlinear waveform distortion.
(ACOUSTICAL SOC AMER AMER INST PHYSICS, 2018-09-01)
Pulsed high intensity focused ultrasound was shown to enhance chemotherapeutic drug uptake in tumor tissue through inertial cavitation, which is commonly assumed to require peak rarefactional pressures to exceed a certain ...
'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 ...
Evaluation of Quality of Life Outcomes Following Palliative Treatment of Bone Metastases with Magnetic Resonance-guided High Intensity Focused Ultrasound: An International Multicentre Study.
(ELSEVIER SCIENCE LONDON, 2018-04-01)
AIMS: To determine quality of life (QoL) outcomes after palliation of pain from bone metastases using magnetic resonance-guided high intensity focused ultrasound (MR-guided HIFU), measured using the European Organization ...
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 ...
Prediction of pelvic tumour coverage by magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) from referral imaging.
(TAYLOR & FRANCIS LTD, 2020-01-01)
BACKGROUND: Patient suitability for magnetic resonance-guided high intensity focused ultrasound (MRgHIFU) ablation of pelvic tumors is initially evaluated clinically for treatment feasibility using referral images, acquired ...
In vitro characterisation of ultrasound-induced heating effects in the mother and fetus: A clinical perspective.
(SAGE PUBLICATIONS LTD, 2020-09-14)
INTRODUCTION: The quantification of heating effects during exposure to ultrasound is usually based on laboratory experiments in water and is assessed using extrapolated parameters such as the thermal index. In our study, ...
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 ...
