  • SYSTEMS AND METHODS FOR ENHANCING EFFICACY OF ULTRASOUND TREATMENT
    Publication number: 20220023670
    Abstract: Embodiments are provided that enhance ultrasound efficacy by for example, high efficiency, signal measurement, calibration, and assurance systems with a control system radio-frequency (RE) driver configured to drive one or more focused ultrasound transducers. The RE driver can comprise one or more power amplifiers including one or more III-V semiconductors, (e.g., gallium nitride GaN, GaAs, GaSb, InP, InAs, InSb, InGaAs, AlSb, AlGaAs, and/or AlGaN) field-effect transistors to efficiently provide high power with distinct narrow-band RE signals over a wide frequency range. The RE driver can include a power measurement and/or calibration system to monitor the amplitude and phase of the RE signal output from the power amplifier and estimate the amount of RE power delivered to the ultrasound transducers.
