X-ray Computed Tomography (CT) scanning is a powerful imaging process for the digitization, exploration and 3D modeling of objects in the natural sciences. It allows for the observation of the internal structures of any type of sample (mineral, fossil, extant) on a sub-micron scale. The finest structures can be selected and extracted as virtual 3D models, and quantified in a repetitive way. These CT-scanned models have applications for the preventive conservation of rare and fragile specimens. The Museum national d'Histoire naturelle, Paris, France, recently acquired a high-resolution CT scan, a v|tome|x L240-180 from GE Sensing and Inspection Technologies phoenix|x-ray, with unique performance capabilities and applications for the natural science field. Indeed, the two x-ray microfocus and nanofocus sources, coupled with a large-size detector, allow for the imaging of samples with extremely variable sizes and densities. Here we present the new MNHN CT scanning Platform “AST-RX” and some results of several projects developed using it.
