Area of Science:

Ultrasound Imaging
Biomedical Engineering
Transducer Technology

Background:

Top orthogonal to bottom electrode (TOBE) arrays offer potential for rapid, high-quality volumetric ultrasound imaging.
Bias-voltage-sensitive TOBE arrays require specialized, fast bias-switching electronics not found in conventional systems.

Purpose of the Study:

To develop novel modular bias-switching electronics for TOBE arrays.
To enable simultaneous transmit, receive, and biasing for every row and column in high-channel-count TOBE systems.

Main Methods:

Designed and implemented modular bias-switching electronics supporting up to 1024 channels.
Integrated the electronics with a transducer testing interface board (IB).
Utilized software-defined reconstruction on channel-domain ultrasound platforms.

Main Results:

Demonstrated 3-D structural imaging of tissue.
Achieved 3-D power Doppler imaging of phantoms.
Showcased real-time B-scan imaging and reconstruction capabilities.

Conclusions:

The developed electronics represent the first modular solution for bias-switchable TOBE arrays.
This advancement facilitates next-generation 3-D ultrasound imaging at unprecedented scales and speeds.
