Abstract: Aspects of the technology described herein relate to ultrasound data collection using tele-medicine. An instructor electronic device may generate for display an instructor augmented reality interface and receive, on the instructor augmented reality interface, an instruction for moving an ultrasound imaging device. The instructor augmented reality interface may include a video showing the ultrasound imaging device and a superposition of arrows on the video, where each of the arrows corresponds to a possible instruction for moving the ultrasound imaging device. A user electronic device may receive, from the instructor electronic device, an instruction for moving an ultrasound imaging device, and generate for display, on a user augmented reality interface shown on the user electronic device, the instruction for moving the ultrasound imaging device. The user augmented reality interface may include the video showing the ultrasound imaging device and an arrow superimposed on the video that corresponds to the instruction.

Abstract: Ultrasound signal processing circuitry and related apparatus and methods are described. Signal samples received from an ultrasound transducer array in an ultrasound transducer based imaging system may be processed, or conditioned, by application of one or more weighting functions. In some embodiments, one or more weighting functions may be applied to the signal samples in the time domain. In other embodiments, the signal samples may be converted to the frequency domain and one or more weighting functions may be applied in the frequency domain. In further embodiments, one or more weighting functions may be applied in the time domain and one or more weighting functions may be applied in the frequency domain. The weighting functions may be channel dependent and/or channel independent. The processed data can be provided to an image formation processor.

Abstract: A time gain compensation (TGC) circuit for an ultrasound device includes a first amplifier having an integrating capacitor and a control circuit configured to generate a TGC control signal that controls an integration time of the integrating capacitor, thereby controlling a gain of the first amplifier. The integration time is an amount of time an input signal is coupled to the first amplifier before the input signal is isolated from the first amplifier.

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 in a substrate. Wafer bonding may also be used to bond the substrate to another substrate, such as a CMOS wafer. At least the second wafer bonding may be performed at a low temperature.

Abstract: Methods and apparatus are described for implementing a coding scheme on ultrasound signals received by a plurality of ultrasonic transducers. The coding, and subsequent decoding, may allow for multiple ultrasonic transducers to be operated in a receive mode simultaneously while still differentiating the contribution of the individual ultrasonic transducers. Improved signal characteristics may result, including improved signal-to-noise ratio (SNR).
