Energy Efficient High Voltage Driver for High Frequency Ultrasound Medical Applications

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...

A Compact Integrated High-Voltage Pulser Insensitive to Supply Transients for 3-D Miniature Ultrasound Probes

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...

Integrated Transceivers for Emerging Medical Ultrasound Imaging Devices: A Review

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...
