Noninvasive brain stimulation plays an essential role in diagnosing and treating diseases of the brain. This stimulation can affect disease-related changes in brain activation, inhibition, or connectivity. Ultrasound neuromodulation is a rapidly growing field of noninvasive brain stimulation. In a form of acoustic pressure waves, ultrasound can...

In this letter, a compact high-voltage (HV) transmit circuit for dense 2-D transducer arrays used in 3-D ultrasonic imaging systems is presented. Stringent area requirements are addressed by a unipolar pulser with embedded transmit/receive switch. Combined with a capacitive HV level shifter, it forms the ultrasonic HV...

As medical ultrasound imaging moves from conventional cart-based scanners to new form factors such as imaging catheters, hand-held point-of-care scanners and ultrasound patches, there is an increasing need for integrated transceivers that can be closely integrated with the transducer to provide channel-count reduction, improved signal quality...
