The present system allows one to observe defects in a thin slice of the object being studied without any interference from adjacent layers. Tomographs of adjacent layers can be added together to give the sum of the whole object. The applicability of a tomographic system depends upon the linear attenuation coefficients of the material to be studied. In the medical case, the linear attenuation coefficient of the various parts of the body may differ by only 0.5%. The linear attenuation coefficients of defects and ceramics (as well as other industrial materials) are quite different than the biological system.
