    Abstract: Aspects of the technology described herein relate to an apparatus including an ultrasound-on-a-chip device configured to be bound to a user's wrist. The ultrasound-on-a- chip device may include a two-dimensional array of ultrasonic transducers. The transducers may be capacitive micromachined ultrasonic transducers (CMUTs) and may be configured to emit ultrasound waves having a frequency between approximately 5-20 MHz. A coupling strip may be coupled to the ultrasound-on-a-chip device to reduce the air gap between the ultrasound-on-a-chip device and the user's wrist. The ultrasound-on-a-chip device may be waterproof and may be able to perform both transverse and longitudinal ultrasound scanning without being rotated. The ultrasound-on-a-chip device may be configured to calculate pulse wave velocity through a blood vessel in a user's wrist.

    Abstract: To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and a high-speed serial data module may be used to move data for all received channels off-chip as digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. Various novel waveform generation techniques, transducer configuration and biasing methodologies, etc., are likewise disclosed. HIFU methods may additionally or alternatively be employed as a component of the "ultrasound- on- a-chip" solution disclosed herein.

    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.
