Acoustic Cavitation Enhances Focused Ultrasound Ablation with Phase-Shift Inorganic Perfluorohexane Nanoemulsions: An In Vitro Study Using a Clinical Device

Figure 4

Representative real-time ultrasound images of the MSNC-PFH and PBS-control phantoms before and immediately after 5 s and 10 s HIFU exposure at a duty cycle of 100%. A bright hyperechoic region (arrowhead) is observed immediately after exposure in both MSNC-PFH and PBS-control phantoms.
