Abstract: Aspects of technology described herein relate to guiding collection of ultrasound data collection using motion and/or orientation data. A directional indicator corresponding to an instruction for moving an ultrasound imaging device relative to a subject may be displayed in an augmented reality display. The direction of the directional indicator in the augmented reality display may be independent of an orientation of the ultrasound imaging device. The augmented reality display may include video captured by a camera that depicts the ultrasound imaging device and a fiducial marker on the ultrasound imaging device. The direction of the directional indicator may be based on the pose of the camera relative to the fiducial marker and the rotation and/or tilt of the ultrasound imaging device relative to the axis of gravity. The direction of the directional indicator may also be based on the pose of the camera relative to the subject.

Abstract: An ultrasonic transducer includes a membrane, a bottom electrode, and a plurality of cavities disposed between the membrane and the bottom electrode, each of the plurality of cavities corresponding to an individual transducer cell. Portions of the bottom electrode corresponding to each individual transducer cell are electrically isolated from one another. Each portion of the bottom electrode corresponds to each individual transducer that cell further includes a first bottom electrode portion and a second bottom electrode portion, the first and second bottom electrode portions electrically isolated from one another.

Abstract: An ultrasound circuit comprising a single-ended 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 TEA is followed by further processing circuitry configured to filter, amplify, and digitize the signal produced by the TIA.

Abstract: Described herein are chargers for wirelessly charging an ultrasound imaging device. The charger may include a base member, a transmitter coil coupled to the base member, and a cradle extending from the top surface of the base member and including a surface configured to receive the ultrasound imaging device, where the first surface is disposed a vertical distance above the top surface of the base member. The cradle may be configured such that no portion of the ultrasound imaging device contacts the top surface of the base member when the cradle holds the ultrasound imaging device. The cradle may be configured to hold the ultrasound imaging device so as to substantially maintain alignment of a receiver coil of the ultrasound imaging device with the transmitter coil.

Abstract: A variable current trans-impedance amplifier (TIA) for an ultrasound device is described. The TIA may be coupled to an ultrasonic transducer to amplify an output signal of the ultrasonic transducer representing an ultrasound signal received by the ultrasonic transducer. During acquisition of the ultrasound signal by the ultrasonic transducer, one or more current sources in the TIA may be varied.
