摘要：
A study of the effect of atherosclerosis on the transmission of ultrasound through the arterial wall was carried out on seven aortas and iliac arteries removed at the time of autopsy. Using a pulsed echo-ranging system, the extent of the sound attenuation was measured from plane sections of the vessels. The results indicated that areas of arterial calcification attenuated the transmitted ultrasound in the 30-40 db range. Normal areas or plaques without calcification, as determined by x-ray and histologic studies, attenuated the sound in the 0-5 db range. Thus, the sound absorption due to the plaque containing calcium is larger by a factor of approximately 1000 than the absorption of the normal artery wall. © 1969.
