—In order to create 3D models used in finite element
analysis, a reconstruction of the structure of metal foam
composites reinforced with ceramic spherical shells is
necessary. A new algorithm has been developed for
reconstruction. The input of the algorithm consists of CT layer
images which were created at the Szechenyi Istvan University,
Györ, Hungary. The CT images were analyzed by the new
algorithm. The algorithm seeks the contours of the spherical
shells by gradually increasing the radii, also in CT images. A
suitably accurate 3D CAD model can be created with algorithm.

processing, μCT, circle fitting.
