Principles of Doppler and Color Doppler Imaging
Rainer Hearten/Michael Mück-Weymann Principles of Doppler and Color Doppler Imaging Due to the need to bridge the gap between haemodynamic questions and the technical means to answer them, this book discusses the fundamentals of Doppler and Color Doppler Sonography. It includes a brief outline of vascular haemodynamics, the physical and technical principles, typical physiological findings, as well as a survery of the most frequently used evaluation procedures in vascular diagnosis, Numerous illustrations and examples of ultrasound images are included to assist in the understanding of Doppler and Color Doppler applications.
