3D X-RAY IMAGE COMPOSITION

3D image reconstruction algorithms fall into one of the three major categories of methods: analytical reconstruction - the filtered backprojection (FBT) method, iterative reconstruction - algebraic reconstruction techniques (ART), statistical image reconstruction techniques (SIRT) and hybrid methods. The analytical methods are based on filtered backprojection (FBP) are currently and widely used on radiology scanners because of their computational efficiency and numerical stability. These mathematical models are applied in X-ray imaging, thermograms, multispectral scanning and many more. Presented study is oriented on X-ray image reconstruction applied in the field of Cultural Heritage investigations, field in which it becomes one of the most important source of information.
