描述Just a very few years after Edler and Hertz had described the clinical use of M-mode echocardiographyl Satomura reported the application of Dop­ 2 pler ultrasound 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) echocardiogra­ phy. Now, however, tremendous growth in the interest of clinicians in the diagnostic use of Doppler ultrasound can be observed and may in fact be due to the recent advent of color flow imaging. The reason for this growth may be that this method makes it possible to directly visualize the blood flow in the cardiovascular system in cross-sectional views. Moreover, the results are reproducible and much easier to understand than the older mapping techniques using a single-gate Doppler. In its short existence many different names have been used to describe this method, for instance, color Doppler, color flow imaging, real-time two-dimen­ sional Doppler echocardiography, and Doppler flow imaging. This diver­ sity reflects the large interest that many researchers have shown in this method. The technical development of color blood flow im

Flexible Code Using Polymorphism there is a maximal measurable flow velocity for a given transducer frequency under a constant angle; this maximum is caused by the strictly limited maximal pulse repetition frequency (prf) for a given depth. If blood velocities exceed the maximal measurable value, aliasing occurs (see p. 8).

Introduction,graphy. Additionally, it offers the option of a comprehensive integration of the various Doppler methods (i. e., single gate pulsed Doppler, continuous wave Doppler) into a very effective diagnostic concept which is easy to understand and quick to learn.

Principles of Color Blood Flow Imaging, there is a maximal measurable flow velocity for a given transducer frequency under a constant angle; this maximum is caused by the strictly limited maximal pulse repetition frequency (prf) for a given depth. If blood velocities exceed the maximal measurable value, aliasing occurs (see p. 8).

Simplify Complex Systems Using Facadesght 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.
