Ultrasonic B-scanning: a computer simulation.
A method has been developed which can predict the appearance and properties of B-scan images. Expand
Evaluation of droplet dispersion during non-invasive ventilation, oxygen therapy, nebuliser treatment and chest physiotherapy in clinical practice: implications for management of pandemic influenza
BACKGROUND Influenza viruses are thought to be spread by droplets, but the role of aerosol dissemination is unclear and has not been assessed by previous studies. Oxygen therapy, nebulised medicationExpand
Measurement of changes in tissue temperature using MR imaging.
The spin-lattice relaxation time T1 of tissue has been measured as a function of temperature using a magnetic resonance imager. Both in vitro and in vivo tissues have been heated within the imagerExpand
A random phased array device for delivery of high intensity focused ultrasound.
Randomized phased arrays can offer electronic steering of a single focus and simultaneous multiple foci concomitant with low levels of secondary maxima and are potentially useful as sources of highExpand
Liver resection with a new multiprobe bipolar radiofrequency device.
HYPOTHESIS Liver resection can be associated with marked blood loss. A novel multiprobe bipolar radiofrequency device (Habib 4X; RITA Medical Systems Inc, Fremont, California) has been developed toExpand
Percutaneous Intraductal Radiofrequency Ablation is a Safe Treatment for Malignant Biliary Obstruction: Feasibility and Early Results
PurposePrevious clinical studies have shown the safety and efficacy of this novel radiofrequency ablation catheter when used for endoscopic palliative procedures. We report a retrospective study withExpand
Measurement of soft tissue motion using correlation between A-scans.
The advent of real-time B-scanning has led to interest in the diagnostic value of the dynamic properties of soft tissue. Present ultrasonic techniques for investigating motion cannot measure theExpand
New Low-Profile Applicators for Local Heating of Tissues
A new type of low-profile applicator is described giving efficient power transfer to tissue with low leakage. Expand
Observation by MR imaging of in vivo temperature changes induced by radio frequency hyperthermia.
Volunteers have undergone radio frequency hyperthermia in a magnetic resonance (MR) imaging system to investigate which of several possible MR parameters would be most convenient and sensitive to useExpand
Modelling and performance analysis of clinical pathways using the stochastic process algebra PEPA
This paper presents a clinical pathway management platform, the Imperial Clinical Pathway Analyzer (ICPA), is introduced for quantitatively analysing clinical pathway. Expand
