 Large Objects Tomographyc System



THE EXPERIMENTAL SETUP 
The CT system used consists of an X-ray tube, mounted on a vertical moving axis, a planar detector made of a GOS scintillating screen and an Electron Bombarded CCD (EBCCD) camera, which can translate both horizontally and vertically, and a rotating platform, on which the globe was placed. 

A motor moved the X-ray tube along an aluminum column. Two more motors moved the detector along the x and y-axis. The main problem of getting a 
complete CT is related to the large size of this masterpiece (220 cm in diameter) and the need of achieving an in situ analysis in a museum surrounded by visitors. The dimension of the planar detector used was 30 × 40 cm2, thus requiring the acquisition of about 32,000 images, for covering the entire Field Of View (FOV).
