We aim to real-time monitor the signal intensity (SI) change of microbubbles in the presence of stable cavitation (SC) effect in a flowing phantom to comprehend the combining effects of SC and flow. Distinct reduced SI was observed, particularly in the focused ultrasound (FUS) focus and downstream regions, during transmitting FUS pulses. More substantial SI changes can be observed with increase of acoustic pressure. In this study, we verified the feasibility of using HASTE sequence to real-time monitor SI changes at the presence of SC effect of MBs in a flowing phantom.
