Abstract: Aspects of the technology described herein relate to built-in self-testing (BIST) of circuitry (e.g., a pulser or receive circuitry) and/or transducers in an ultrasound device. A BIST circuit may include a transconductance amplifier coupled between a pulser and receive circuitry, a capacitor network coupled between a pulser and receive circuitry, and/or a current source couplable to the input terminal of receive circuitry to which a transducer is also couplable. The collapse voltages of transducers may be characterized using BIST circuitry, and a bias voltage may be applied to the membranes of the transducers based at least in part on their collapse voltages. The capacitances of transducers may also be measured using BIST circuitry and a notification may be generated based on the sets of measurements.

Abstract: Aspects of the technology described herein related to controlling, using control circuitry, modulation circuitry to modulate and delay first ultrasound data generated by first ultrasound transducers positioned at a first azimuthal position of an ultrasound transducer array of an ultrasound device and second ultrasound data generated by second ultrasound transducers positioned at a second azimuthal position of the ultrasound transducer array of the ultrasound device, such that the first ultrasound data is delayed by a first delay amount and the second ultrasound data is delayed by a second delay amount that is different from the first delay amount. The first and second ultrasound data received from the modulation circuitry may be filtered and summed. The ultrasound transducer array, the control circuitry, the modulation circuitry, the filtering circuitry, and the summing circuitry may be integrated onto a semiconductor chip or one or more semiconductor chips packaged together.

Abstract: A processing device is coupled to a single ultrasound device having a single array of capacitive micromachined ultrasound transducers (CMUTs). The processing device generates a graphical user interface (GUI) having user selectable GUI menu options corresponding to respective ultrasound operating modes for the single ultrasound device having the single ultrasound transducer array. The user-selectable GUI menu options include GUI menu options labeled as representing an ultrasound operating mode for musculoskeletal imaging, breast imaging, carotid imaging, vascular imaging, and abdominal imaging, respectively. The processing device further receives, via the GUI, user input indicating selection of one of the ultrasound operating modes, and in response to receiving the user input, provides an indication to the single ultrasound device having the single array of CMUTs to operate in the selected ultrasound operating mode.

Abstract: Aspects of the technology described herein relate to wirelessly offloading, from a wearable ultrasound device, ultrasound data sufficient for forming one or more ultrasound images therefrom. The wearable ultrasound device may include an ultrasound patch. Indications that may be monitored with such a device, and therapeutic uses that may be provided by such a device, are also described. Methods and apparatuses are also described for compounding multilines of ultrasound data on an ultrasound device configured to collect the ultrasound data. Additionally, certain aspects of the technology relate to non-uniform grouping of ultrasound transducers that share a transmit/receive circuit in an ultrasound device.

Abstract: Circuitry for ultrasound devices is described. A multi-level pulser is described, which can support time-domain and spatial apodization. The multi-level pulser may be controlled through a software-defined waveform generator. In response to the execution of a computer code, the waveform generator may access master segments from a memory, and generate a stream of packets directed to pulsing circuits. The stream of packets may be serialized. A plurality of decoding circuits may modulate the streams of packets to obtain spatial apodization.
