Abstract: Methods and systems are provided for ultrasound imaging. In one example, a method includes receiving ultrasound signals of a region of interest with a wireless hand-held probe assembly, generating a plurality of received digital signals based on the received ultrasound signals within the wireless hand-held probe assembly, generating each of a larger dataset and a smaller dataset from the plurality of received digital signals, transmitting the smaller dataset from the wireless hand-held probe assembly to a hub via a lower bandwidth wireless connection, transmitting the larger dataset from the wireless hand-held probe assembly to the hub via a higher bandwidth wireless connection, generating each of a low resolution image from the smaller dataset and a high resolution image from the larger dataset at the hub, and transmitting the low resolution image from the hub to a first display and the high resolution image from the hub to an electronic device.

Abstract: An ultrasound pulse generator circuit includes a first gate driver electrically coupled to a first gallium nitride (GaN) transistor, a second gate driver electrically coupled to a second GaN transistor, a first snubber circuit, a second snubber circuit, and a transformer. The first snubber circuit and the second snubber circuit each include a respective capacitor and resistor and each snubber circuit is configured to clamp a voltage overshoot when present. Further, the transformer generates an output signal when operated and the third transformer is electrically connected downstream of the first GaN transistor, the second GaN transistor, the first snubber circuit, and the second snubber circuit. In addition, the transformer includes multiple windings.
