Acoustic Characterisation of Individual Targeted Microbubbles with High-Frequency Ultrasound

Abstract:

The acoustic response of individual targeted microbubbles, sized optically, to high-frequency ultrasound was examined to improve nonlinear imaging techniques and aid signal quantification. Single bound phospholipid shell microbubbles (diameters 1.0 to 5.0 mu;m) were insonated with 30 MHz Gaussian-shaped pulses for pressures from 20 kPa to 4 MPa with a fractional-6dB one-way bandwidth of 20%. The scattering cross-section, subharmonic and second harmonic SNR, and microbubble disruption (determi...
