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: 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 an output data module may be used to move data for all received channels off-chip as a 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. The on-chip digitization of received signals also enables the on-chip integration of ultrasound processing and/or pre-processing to reduce the burden on off-chip computing. Data compression architectures are disclosed to facilitate the transfer of data off-chip as a digital data stream in accordance with the bandwidth requirements of standard commercially- available output interfaces.

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: Programmable ultrasound probes and methods of operation are described. The ultrasound probe may include memory storing parameter data and may also include a parameter loader which loads the parameter data into programmable circuitry of the ultrasound probe. In some instances, the ultrasound probe may include circuitry grouped into modules which may be repeatable and which may be coupled together to allow data to be exchanged between the modules.

Abstract: Circuitry for ultrasound devices is described. A multilevel pulser is described, which can provide bipolar pulses of multiple levels. The multilevel pulser includes a pulsing circuit and pulser and feedback circuit. Symmetric switches are also described. The symmetric switches can be positioned as inputs to ultrasound receiving circuitry to block signals from the receiving circuitry.

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: An ultrasound circuit comprising a multi-stage trans-impedance amplifier (TIA) is described. The TIA is coupled to an ultrasonic transducer to amplify an electrical signal generated by the ultrasonic transducer in response to receiving an ultrasound signal. The TIA may include multiple stages, at least two of which operate with different supply voltages. The TIA may be followed by further processing circuitry configured to filter, amplify, and digitize the signal produced by the TIA.
