While the spectral display for a single gate pulsed Doppler system will prevent the investigator 48 from a false evaluation tf the detected Doppler frequencies exceed (to some extent) the maximal detectable Doppler frequency (alias,-, ing) , no such warning is available for multi-gate pulsed Doppler systems. Aliasing is more likely to occur in high-resolution multigate pulsed Doppler systems because of the high emission frequency employed. That is why it is essential that the detection of the average velocity in each of the sampIe volumes is executed properly especially if the major interest is in the amplitude of the detected velocity signal.

Therefore, they are useful tools to explore the heart cavities for septum fects, to quantify (regurgitantl de- jets through heart valves and to determine the degree of narrowing of the aorta due to stenoses. Hemodynamic disorders are recognized on the basis of the recorded velocity distribution rather than the frequency content of the Doppler signal originating from a single sampIe volume. Special attention has to be paid to the increase of the limited velocity- 44 range product of pulsed Doppler systems, which presently prevents proper detection of high blood velocities in the cardiac cavities.
