Abstract:

This research aims to evaluate the internal structure of concrete material configuration using an immersed ultrasonic computed tomography imaging technique. We propose a relative difference method of time of flight data to remove distortions in imaging process of concrete. Time of flight data for 306 paths were measured in total by manual scanning for one computer tomography image, we examined interpolation of time of flight data as the density which has a considerable effect on image quality in Filtered Back Projection (FPB) method. The relative difference of time of flight and interpolation is examined in detail using concrete phantoms. The accuracy of defect detection in concrete was significantly improved by the proposed technique.
