High Speed Interface For Myocardial Sonicated Echocontrast Studies

Quantitative measurement of regional myocardial perfusion would be invaluable for the detection and treatment of ischemic heart disease. Sonicated echocontrast agents now allow 2-D ultrasound scanners to track blood flow, but commercial scanners distort the received signal to produce visually pleasing images. To capture digitized radiofrequency (rf) envelope signal suitable for quantitative analysis before video processing, a real-time system for computer acquisition of echocardiogram data (CAED) was constructed.
