Bio-Inspired "MRI" of Concrete Bridges using Waveform-Based Ultrasonic Tomography

Bridges can have deep subsurface concrete damage and it can be difficult to measure and analyze the damage.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 205-A: Bio-Inspired "MRI" of Concrete Bridges using Waveform-Based Ultrasonic Tomography details the development of an innovative measurement and data processing approach of waveform-based ultrasonic tomography to generate tomographic images of sub-surface defects in structural concrete using a single measurement linear wave velocity method and an acoustic nonlinearity coefficient.
