Advanced Ultrasonic Imaging Research

Trahey Lab at Duke University, Pratt School of Engineering

KEYWORDS: Medical Ultrasound, Breast Imaging, Adaptive Imaging, Medical Imaging, Flow Imaging, Acoustic Radiation Force Imaging.

Research in Dr. Trahey's laboratory focuses on experimental investigations of advanced ultrasonic imaging methods with a focus on breast imaging. The laboratory's experimental capabilities are centered around several state-of-the-art clinical phased array scanners in facilities in the Pratt School of Engineering and the Duke University Medical Center Breast Clinic. Through collaborative agreements with Siemens Ultrasound, researchers in Dr. Trahey's laboratory are able to reconfigure these scanners in novel imaging modes, connect custom transducers and circuitry to these scanners, and collect raw radio-frequency data from individual elements or collections of elements during clinical or phantom trials. Students in this laboratory design custom transducer arrays, program ultrasonic scanners to implement novel methods of transmitting ultrasonic signals and processing echoes, and conduct theoretical, clinical, and phantom trials of these methods.
