Image Enhancement by Volume Limitation in Binary Tomography

摘要

We introduce two methods to limit the reconstruction volume in binary tomography. The first one can be used when the CT scanner is equipped with a laser distance measurement device which gives information of the outer boundary of the object to reconstruct. The second one uses dilated versions of a blueprint of the object under investigation. Such a blueprint is often available in non-destructive testing of industrial objects. By experiments we show that the proposed methods can enhance the quality of the reconstructed images.
