To determine whether collagen content may be a determinant of the ultrasonic attenuation and backscatter in myocardium and to identify factors in the measurement of the backscatter coefficient needed for ultrasonic characterization of myocardium in vivo, two series of experiments were conducted. In the first series, the ultrasonic attenuation was measured from 110 regions in 18 dogs studied 2, 4, and 6 weeks after coronary occlusion. The increased slope of the attenuation of regions within… CONTINUE READING
