3D Micro Computed Tomography Principle Acquisition Reconstruction Visualization
3D Micro-CT (Micro Computed Tomography) is a non destructive X-ray technique for internal expertise and volume digitization. Definition
Volume digitization (volumical data)
Complete digitization of entire objet, without shaded zone
Compatible with all material, even black, brillant and transparent surfaces
Closed wooden box : how to discover internal and invisible objects
Real Picture 3D rendering (possibility to apply mapping textures) Grenoble Museum’s collection African sculpted box. MHNGr.1979.633
African sculpted box. MHNGr.1979.633 The internal view with transparency of the wood reveals shellfishes, plants and grains. In fact it seems to be a shellfish necklace. Shellfish virtual extraction by selection of an expected range of density. 3D virtual cross-section to discover the inner objects Grenoble Museum’s collection
Talisman : discover all about mysterious objects
Lyon Museum’s collection Talisman from Madagascar External volumical view of an african talisman Segmentation of high density components : 3D view of the hook and dicovery of a pearl. 2D high resolution CT slices of the pearl and the hook
Talisman from Madagascar Lyon Museum’s collection 3D surface rendering of the hook and the pearl : detailed views and transparent rendering
Paleolagus Fossil : how to virtually extract bone from stone
Grenoble Museum’s Collection Paleolagus haydeni, Wyoming (USA), oligocène. Digitalization and 3D volume rendering of a 35 million years fossil. The aim of microCT scanning is here to study the skull by virtually removing the stone.
Paleolagus haydeni, Wyoming (USA), oligocène. Grenoble Museum’s Collection Virtual extraction of the bone and real time 3D visualization
Hornet Very high resolution digitalization applied to insects – internal 3D anatomy analysis.
Rodent : classification of the animal by studying internal teeth
3D real time cross sections of the teeth to determine the specie Grenoble Museum’s collection After comparison with literature schemes, we can classify the specie : this rodent is an Arvicola terrestris
Ostracod fossil Real size 2mm Rabbit’s bone Junon – Le Louvre
Computed Tomography of a small clay pompeian head CT of a cat shaped coffin CT and reconstruction made by University of Bologna, Physics department A cat mummy exposed at the Egyptian section of the City Museum of Bologna It is possible to see the rest of a cat skeleton without opening the coffin.
