In the past few years, a great progress was done in the field of acoustical imaging. One aspect of this progress has been the application of this evolving technique to the non-destructive evaluation of civil engineering structures. This paper gives a brief review of the basic theory of acoustical imaging. It also describes a case study to highlight the practical aspects and the possibility of using this technique to assess the internal conditions of concrete structures.
