Use of Passive Arrays for Characterization and Mapping of Cavitation Activity during HIFU Exposure

Abstract:

Inertial cavitation occurring during HIFU exposure act both as a promoter and as a marker of heat deposition, bubbles re-radiate part of the incident field as noise emissions that are detectable over a frequency far removed from the main HIFU excitation frequency. In present work, a commercially available ultrasound scanning (with the transmit signal turned off) and linear array are to detect the emissions emanating from cavitating bubbles on 64 independent channels during HIFU exposure. A al...
