    Abstract: Ultrasound devices configured to perform high-intensity focused ultrasound (HIFU) are described. An ultrasound device may include HIFU units configured to emit high acoustic intensities. Multiple ultrasound devices may be disposed on a substrate, which may be configured to be flexed so that the direction of emission of the ultrasound devices can be mechanically controlled. Additionally, or alternatively, the ultrasound beams produced by different ultrasound devices may be electronically oriented by adjusting the phases of the signals with which each element of a device is driven. For example, multiple phased arrays of ultrasound devices may be used to concentrate ultrasound energy into a desired location. In some embodiments, the time at which different ultrasound signals are emitted may be controlled, for example to ensure that the combined signal has at least a desired intensity.

    Abstract: Aspects of the technology described herein relate to an ultrasound device including a first die that includes an ultrasonic transducer, a first application- specific integrated circuit (ASIC) that is bonded to the first die and includes a pulser, and a second ASIC in communication with the second ASIC that includes integrated digital receive circuitry. In some embodiments, the first ASIC may be bonded to the second ASIC and the second ASIC may include analog processing circuitry and an analog-to-digital converter. In such embodiments, the second ASIC may include a through-silicon via (TSV) facilitating communication between the first ASIC and the second ASIC. In some embodiments, SERDES circuitry facilitates communication between the first ASIC and the second ASIC and the first ASIC includes analog processing circuitry and an analog-to-digital converter. In some embodiments, the technology node of the first ASIC is different from the technology node of the second ASIC.
