ABSTRACT
The word tomography consists of two separate Greek words: τομοσ (slice, section) and γροφοσ (to write). So, tomography is similar to a "write sections" procedure, that is, a division of the structure of the object under investigation into slices. Wave tomography records information on each element of the object under investigation by use of numerous integral projections under various angles with respect to the direction of the investigated object. Radio, optical, and acoustic wave tomography are separate novel directions of physical tomography, and have recently been used for sounding, visualization, and reconstruction of various objects, features, and processes presented and occurring in the environment, as well as anomalous occurrences on and in the human body. In all types of wave tomography, the wave nature of any radiation is usually used during investigations carried out to understand deeply the inner and outer nature of the objects under investigation.
