ABSTRACT
It is widely acknowledged that Ultrasonic Computed Tomography (UCT) technology may provide a considerable monitoring approach while describing the inner defects, which cannot be observed by naked eyes. And also, the UCT technology can be adopted to detect defects in stones belonging to ancient building or archaeological sites. This paper aims to introduce the work which is concerned with the UCT technology to evaluate the defects inside stone. The result shows that UCT technique is a compromising app roach to trace and detect the damage level inside stone, especially for the weathering defects from surface.
