An investigation of the use of a doppler technique to Study acoustic streaming in biological fluids
Acoustic streaming generated by diagnostic ultrasound fields is an important area for study both for safety reasons and because it has potential application as a diagnostic tool. A method of investigating streaming in biological fluids is reported. A number of fluids were insonated using a 3.5 MHz weakly focused single element transducer which was driven in pulsed mode. Streaming was detected in each fluid using an 8 MHz continuous wave Doppler system and the maximum streaming velocity was obtained by spectral analysis of the Doppler signal. Using this system longitudinal streaming profiles were measured. At an acoustic power of 150 mW the maximum streaming velocities detected were: 9.3 cms-1 in water, 6.8 cms-1 in 4.5% human serum albumin (HSA) solution and 4.9 cms-1 in blood.
