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: Described herein are arrays of piezoelectric ultrasound elements. The piezoelectric ultrasound elements may be arranged in a checkerboard pattern. The piezoelectric ultrasound elements in one column may be shifted along the vertical dimension of the array with respect to piezoelectric ultrasound elements in an adjacent column. A piezoelectric ultrasound element in one column may be coupled to a different circuit than all other piezoelectric ultrasound elements in the column. The circuit may be, for example, an analog-to-digital converter or a circuit configured to transmit ultrasound signals from the array. Each piezoelectric ultrasound element in a column may be configured so that it can operate at a different frequency from each of the other piezoelectric ultrasound elements in the column. There array may include at least 1,000 piezoelectric ultrasound elements. The array may be monolithically integrated with a substrate comprising different circuits for each piezoelectric ultrasound element in the array.

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.

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: Ultrasound devices are described. The ultrasound devices may be flexibly configured to output a certain number of multilines per channel of ultrasound data and to process certain channels of ultrasound data per processing cycle. The ultrasound device may then be configured to either output more multilines per channel and process fewer channels per processing cycle, or output fewer multilines per channel and process more channels per processing cycle. In other words, the circuitry may be configured to change to a configuration with increased resolution and increased processing time or to a configuration with decreased resolution and decreased processing time.
