Comparison of volumetric reconstructions obtained from CT and micro-CT scans of the petrous bone

is study presents effects of volumetric reconstructions of the petrous bone anatomy obtained from image data delivered by the medical CT scanner (Optima CT 660) and micro-CT scanner (Nanotom 180N) used in biological and technical applications. Although most of the osseous structures of the ear were visible in the subsequent serial CT scans delivered by the computed tomography system (Optima CT 660), their composition into volume was not satisfactory for viewing as a three-dimensional reconstruction. Micro-CT imaging of the anatomical structures of the petrous bone performed by the Nanotom 180N device was considerably superior to the medical computed tomography and the reconstructed anatomical structures presented a high level of accuracy and very realistic appearance.
