Abstract: An ultrasound device is described configurable to operate in a variety of modes. At least some of the modes are associated with different frequencies of ultrasound signals. A system is also described, comprising a multi-modal ultrasound probe configured to operate in a plurality of operating modes associated with a respective plurality of configuration profiles and a computing device coupled to the handheld multi-modal ultrasound probe and configured to, in response to receiving input indicating an operating mode selected by a user, cause the multi-modal ultrasound probe to operate in the selected operating mode.

Abstract: Ultrasound devices and methods are described, including a repeatable ultrasound transducer probe having ultrasonic transducers and corresponding circuitry. The repeatable ultrasound transducer probe may be used individually or coupled with other instances of the repeatable ultrasound transducer probe to create a desired ultrasound device. The ultrasound devices may optionally be connected to various types of external devices to provide additional processing and image rendering functionality.

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: Ultrasound signal processing circuitry and related apparatus and methods are described. Groups of signal samples corresponding to respective acquisitions performed by an ultrasound transducer array may be processed by being transformed to the Fourier domain and via the application of one or more weighting functions. The transformed groups of signals may be combined with one another in the Fourier domain to obtain a Fourier-compounded set of signals that may be used for image formation.

Abstract: Complementary metal oxide semiconductor (CMOS) ultrasonic transducers (CUTs) and methods for forming CUTs are described. The CUTs may include monolithically integrated ultrasonic transducers and integrated circuits for operating in connection with the transducers. The CUTs may be used in ultrasound devices such as ultrasound imaging devices and/or high intensity focused ultrasound (HIFU) devices.

Abstract: An ultrasound device, comprising: at least first and second ultrasonic transducer elements; a first transmit control circuit comprising: a first pulser coupled to the first ultrasonic transducer element so as to drive the first ultrasonic transducer element so that the first ultrasonic transducer element emits an ultrasonic pulse; a first waveform generator coupled to the first pulser to provide a first waveform to the first pulser in response to receipt, by the first transmit control circuit, of a transmit enable signal generated by a timing and control circuit; and at least one first component that impacts a length of a first delay between when the first transmit control circuit receives the transmit enable signal and when the first waveform is applied to the first pulser; a second transmit control circuit comprising: a second pulser coupled to the second ultrasonic transducer element so as to drive the second ultrasonic transducer element so that the second ultrasonic transducer element emits an ultrasonic pulse; a second waveform generator coupled to the second pulser to provide a second waveform to the second pulser in response to receipt, by the second transmit control circuit, of the transmit enable signal generated by the timing and control circuit; and at least one second component that impacts a length of a second delay between when the second transmit control circuit receives the transmit enable signal and when the second waveform is applied to the second pulser; wherein the at least one first component is configured differently than the at least one second component, so that the length of the second delay is different than the length of the first delay, and wherein the first and second ultrasonic transducer elements, the first transmit control circuit, and the second transmit control circuit are formed on a single solid state semiconductor die. c-o

Abstract: Micromachined ultrasonic transducers integrated with complementary metal oxide semiconductor (CMOS) substrates are described, as well as methods of fabricating such devices. Fabrication may involve two separate wafer bonding steps. Wafer bonding may be used to fabricate sealed cavities (306) in a substrate (302). Wafer bonding may also be used to bond the substrate (302) to another substrate (304), such as a CMOS wafer. At least the second wafer bonding may be performed at a low temperature.
