In Vitro Demonstration of Focused Ultrasound Thrombolysis Using Bifrequency Excitation

Figure 7

Temperature rise along transverse axis for a monofrequency excitation (black crosses) and a bifrequency excitation (red asterisks), after of pulsed sonication 10% duty cycle. The power is equal to for both cases. The origin represents the intersection with the acoustical axis of the transducer.
