Application of Ultrasonic Tomography Technology to Concrete Structures

In recent years,ultrasonic tomography method has been widely applied to the integrity testing of concrete structures,and good results have been achieved.In this paper,the basic principles of CT imaging are described in details,and Radon transform and its inverse transform formulation for CT technology is derived.Furthermore,through application of tomography method to concrete structures,the results show that it can reach the better precision and higher efficiency.
