Marc E. Frischer,Peter G. Veritylume from extent and duration of aortic cusp separation. We proceeded to record the aortic valve and root echo simultaneously with measurements of cardiac outputs using the indicator dilution technique in the cardiac catheterization laboratory. It was then a routine practice at the University of Roc

To place microbubble phenomena in context, it was deemed useful to consider parallel multidisciplinary efforts in such areas as hydrodynamic cavitation, diving physiology and bubbly flow processes. Although there are many applications of ultrasound contrast, one difficult but

Marc E. Frischer,Peter G. Verityo water to entrained air bubbles Minnaert has since shown that the sound generated by gas bubbles in liquids is associated with simple volume pulsation of the bubble without changing shape. The bubble behaves as a simple damped oscillating system with one degree of freedom. Therefore, the differ

Smoke-like SEC is described as an amorphous, swirling, light gray haze . Its configuration and acoustic density change when observed over sev

Joanna M. Cain,Kathleen C. Bowlinglements to achieve their objective. Iodine is radio-opaque and the powerfully paramagnetic rare earths such as gadolinium decrease proton relaxation time, shortening T1 and T2 times and brightening the tissues that take them up.

Part-Time Faculty and Their Hidden Value, by Gramiak and Shah in 1968 . Twenty-eight years later, microbubbles remain the standard echocontrast enhancers. They have been used clinically to verify the presence of intracardiac shunts and valvular regurgitation and for the measurement of cardiac output . Contrast echocardiogr
