It is extremely important to study chailges of ultrasonic properties of
hunian blood during coagulation for improving ultrasonic diagnosis of blood
dyscrasies.
In this paper, ultrasonic properties (ultrasonic velocity, attenuation
coefffcient, back-scattering, nonlinearity parameter B/A ) are studied in
vitro for both natural and anticoagulated blood.
It is shown that for natural coagulative blood of more than 10 h in
vitro, ...
