A Comparative Study of Algebraic and Backprojection Reconstruction Techniques for Concrete Ultrasonic Tomography

Abstract

AbstractUltrasonic tomography is a promising nondestructive technique for evaluating the internal state of concrete elements, which is crucial for maintaining the sustainability and safety of civil infrastructures. In civil engineering, ongoing research ...Ultrasonic testing around a concrete element with voids is used to generate tomographic images. Four reconstruction algorithms - OLS, SIRT, ART, and FBP - are evaluated with different measurements, mesh configurations, and iterations. Images on the right ...Practical ApplicationsThis study offers valuable insights into the use of ultrasound tomography, a nondestructive testing method, for analyzing the interior concrete elements in civil engineering. It compares four techniques—simultaneous iterative ...
