Biomedical Applications of Diagnostics and Measurements by Industrial Computer Tomography
The aim of presented study is a review on biomedical applications of industrial computed tomography (CT). Industrial CT enables in contrast to medical CT scanning of technical materials (plastic materials, low density metals, wood, etc.) but also living tissues in vitro. Important parameters for scanning are maximum size of the part 300 x 300 x 300 mm; and the best obtainable resolution of the digitalized scan is 9 μm. The termination for the scanning is also density of material, where low density medical materials like titanium or medical polymers are applicable. Presented review shows potentials of industrial CT for biomedical applications; an assembly inspection, damage analysis, inspection of materials, porosity analyses, conventional defect, and the reverse engineering.
Paper presents several biomedical studies realized by industrial CT, including epithetic foot and obtained 3D model for inner structures and materials analysis, epithetic hand glove for material homogeneity analysis, where recent thickness is required, reverse engineering of human teeth to get the STL file for further applications (fabrication by additive manufacturing), animal skulls scanning and digitalization for preservation of museum exhibits, scanning of orthosis and total hip replacements. The end of the study shows the full process of porous implant design, using metrotomographic bone-like porous structure.
