Abstract
The authors report the design of a multichannel data acquisition system for the visualization of intracardiac blood flows. The system permits the simultaneous measurement of signals backscattered from blood cells and cardiac structures. The image parameters, the mean Doppler frequency and frequency distribution, were calculated from the Doppler spectrum, and the cardiac image was also estimated from a signal amplitude. This information was reconstructed by minicomputer and was displayed on a color device.
