| Summary: | In this contribution a coherent relation between the algebraic and the
transform-based reconstruction technique for computed tomography is
introduced using the mathematical means of two-dimensional signal processing.
There are two advantages arising from that approach. First, the algebraic
reconstruction technique can now be used efficiently regarding memory usage
without considerations concerning the handling of large sparse matrices.
Second, the relation grants a more intuitive understanding as to the
convergence characteristics of the iterative method. Besides the gain in
theoretical insight these advantages offer new possibilities for
application-specific fine tuning of reconstruction techniques. |
