Visualization of transitional pipe flow using the photochromic tracer method

Autor: Paul Zalzal, Matadial Ojha, R. S. C. Cobbold, C. R. Ethier, K. W. Johnston

Publikováno v: Physics of Fluids. 6:2003-2010

Two noninvasive measurement techniques are described for investigating transitional flow in a rigid straight tube. Photochromic trace recordings, representing fluid displacement profiles, were made within the core and at the leading and trailing edge

Iliac arteries: reanalysis of results of balloon angioplasty

Autor: K W Johnston

Publikováno v: Radiology. 186:207-212

In this reanalysis of the 667 percutaneous transluminal balloon angioplasties (PTAs) of the iliac arteries, the variables that are predictive of early and late success were identified. For 82 iliac occlusions, the success rate at 1 month was 75.6% +/

Femoral and popliteal arteries: reanalysis of results of balloon angioplasty

Autor: K W Johnston

Publikováno v: Radiology. 183:767-771

The author presents an alternative statistical analysis of the results of the University of Toronto series of percutaneous transluminal angioplasty (PTA) of the femoral and popliteal arteries (n = 254). After recalculation of the data with the Kaplan

Carotid artery stenting: to be or not to be?

Autor: D. S. Moneley, A. Dueck, K. W. Johnston

Publikováno v: The surgeon : journal of the Royal Colleges of Surgeons of Edinburgh and Ireland. 6(1)

Carotid endarterectomy (CEA) has been the standard of care for suitable patients with symptomatic or asymptomatic high grade carotid stenosis since the landmark NASCET (North American Symptomatic Carotid Endarterectomy Trial), ECST (European Carotid

Spinal cord compression from precipitation of drug solute around an epidural catheter

Autor: M. K. W. Johnston, S. P. Harland

Publikováno v: British Journal of Neurosurgery. 12:445-447

We report a previously undescribed complication of long-term epidural catheter placement for the administration of analgesia in terminal malignancy. Spinal cord compression resulted from a drug-related precipitate forming around the epidural catheter

Problems In The Quantitative Assessment Of Pulsed Doppler Spectra

Autor: Richard S.C. Cobbold, K. W. Johnston, Y.F. Law, P.A.J. Bascom

Publikováno v: [1990] Proceedings of the Twelfth Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

A theoretical and experimental study of the influence of spectral broadening on the pulsed Doppler spectrum is presented. Specifically, the effect of sample volume size and position on the spectrum is discussed with particular emphasis placed on how

Waveform dependence of wall shear stresses in a human right coronary artery

Autor: K. W. Johnston, Jerry G. Myers, M. Ojha, C.R. Ethier, J.A. Moore

Publikováno v: Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015).

Wall shear stress patterns in a realistic model of a human right coronary artery (RCA) were numerically studied for two different flow waveforms. For both waveforms, the distribution of mean wall shear stress was very similar while the oscillatory sh
