Abstract
Estimation of vibration amplitude of intra-capillary micro-bubbles driven to vibrate with an incident ultrasound wave with amplitude and frequency to adjust the drive amplitude of the incident wave to obtain specified vibration amplitude of extra-capillary tissue. Estimation uses transmission of M groups of pulse complexes having low frequency pulse (LF) at bubble drive frequency, and high frequency (HF) pulse with angular frequency ω>˜5ω, and pulse duration shorter than π/4ωalong HF beam. The phase between HF and LF pulses is ωtfor each group, where tvaries between the groups. Within each group, LF pulse varies between pulse complexes in amplitude and/or, where the LF pulse can be zero for a pulse complex, and LF pulse is different from zero for pulse complex within each group. HF receive signals are processed to obtain a parameter relating to bubble vibration amplitude when the HF pulse hits bubble.
