Digital endocasts of the cranial surface generated by the 3D vision system

Skrzat J., Sioma A.

Bio-Algorithms and Med-Systems

2013

Vol. 9, no. 4

179--182

This article demonstrates a technique of generating digital endocasts of the cranial interior using the three-dimensional (3D) vision system. Obtained digital endocasts reflected the shape and size of the brain, pattern of dural vascularization, position, and interlocking of the cranial sutures. Hence, some minor anatomical structures (granulations faveole, digital impressions) were recorded by the 3D vision system and were revealed on the digital endocasts.

Digital skeletonization as a probe of correlation between sutural bones and diffusion limited agreggation clusters

Skrzat J., Walocha J.

Bio-Algorithms and Med-Systems

2008

Vol. 4, no. 7

57--61

Skeletonization of the digital images of the sutural bones and computer generated clusters formed by diffusion limited aggregation process (DLA) revealed branch-like patterns underlying the shape of these objects. Density of DLA cluster is determined by the ratio of particle size to distance a particle moves in one step. Skeletons of DLA clusters aggregated from particles whose size was 20 pixels show the most similar fractal dimension to the skeletons of sutural bones. The skeletons obtained from DLA clusters formed by lesser (5,10 pixels) or bigger (30,40,50 pixels) particles are less accurate to model basic pattern underlying shape of the sutural bones because of divergences in their fractal dimension.
