Phase contrast flow imaging in Cardiac Magnetic Resonance (CMR): Imaging turbulent blood flow
Background Accurately measuring blood flow volume is paramount in patients with arterial valve disease. Flow measurements are important components of a CMR report and provide the referring clinicians with valuable information from which to base further clinical management. There are many factors which influence the quality and reliability of flow data including; slice positioning, velocity enco...
متن کاملQuantum imaging of current flow in graphene
Since its first discovery in 2004, graphene has been found to host a plethora of unusual electronic transport phenomena, making it a fascinating system for fundamental studies in condensed matter physics as well as offering tremendous opportunities for future electronic and sensing devices. Typically, electronic transport in graphene has been investigated via resistivity measurements; however, ...
متن کاملImplementation issues in ultrasonic flow imaging.
This article addresses several implementation issues in ultrasonic flow imaging. We discuss frequency-dependent scattering and attenuation, use of interpolation for computation intensive methods and implications of the use of chirps to increase bandwidth. We also discuss wall filtering issues; our observations show that the butterfly search estimator may be capable of detecting flow in the vici...
متن کاملColor Flow Imaging in Clinical Practice
Doppler color flow imaging is a method for noninvasively imaging blood flow through the heart by displaying flow data on the two-dimensional echocardiographic image. This capability has generated great excitement about the use of the technique for identifying valvular, congenital, and other forms of heart disease, as the color flow image imparts spatial information to the Doppler data. To inexp...
