Preface,trasound to the study of cardiac function.. Yet Doppler ultrasound has been integrated into diagnostic practice in cardiology much more slowly than conventional (M-mode and two-dimensional) echocardiography. Now, however, tremendous growth in the interest of clinicians in the diagnostic use of Doppl

Introduction,ascinating features, which will be shown in a variety of examples and demonstrate that this noninvsive and harmless method can give important diagnostic information. The reliability of its qualitative and semi-quantitative results equals that of the invasive and much more risky method of angiocardio

Principles of Color Blood Flow Imaging,f energetic waves. The Doppler shift caused by the ultrasound reflection from the corpuscles of the flowing blood is used as a means to investigate blood flow. CBFI utilizes the range-gating properties, i. e., pulsed emission and reception, of ultrasound waves. The pulsed mode leads to the fact that

Color Display of Blood Flow Velocities,athological flow conditions in different forms of heart disease. As will be seen, there are only a few archetypical flow patterns and the knowledge of these will make the recognition of pathological states much easier.

Physiological Flow Velocity Patterns in the Cardiovascular System,e heart and the great vessels. The spatial as well as the temporal distribution for every compartment will yield a topography of flow behavior in the cardiovascular system. The directions in normal as well as in pathological states, however, do not always obey the rules for the standardization of ec

Blood Flow Velocity Patterns in Heart Disease,ght place at the right time with normal velocities (right in space, right in time, right in velocity). Pathological flow patterns in heart disease may exhibit pathological characteristics, such as turbulence and vortex formation, or they may occur at the wrong time or at the wrong location.
