Abstract

The behavior of engineering systems is highly dependent on the distribution of material parameters. The goal of tomographic imaging is to invert boundary measurements to determine the field of a parameter. This paper reviews difficulties in tomographic imaging, summarizes inversion methods and ray tracing algorithms, and presents a comparative study of matrix-based inversion methods for simulated, laboratory, and field data. The effect of errors in ray-paths and travel times is assessed.
