Abstract: Ultrasound devices, and associated methods of assembly thereof, are disclosed whereby an annular electrode array of an ultrasound transducer is electrically connectedto a flexible printed circuit board in a compact configuration. The flexible circuit board includes an elongate flexible segment and a distal distribution segment, where the distribution segment is attached to a peripheral support ring that surrounds at least a portion of the ultrasound transducer. The distribution segment includes a plurality of spatially distributed contact pads, and electrical connections are provided between the contact pads and the annular electrodes of the annular array.

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.

Abstract: Among other things, in general, an acousto-mechanical transducer for the interconversion of electricity and acoustic waves is described. Methods are also described for the construction of such transducers.
