Multislice Tomography   CT analysis of two Painted "Tablets", Gentile da Fabriano With collaboration of National Art Gallery of Bologna

 The two tablets, represent two holy (Holy Apostle and Holy Apostle with book), are between 1410 and 1415. They are attributed to Gentile from Fabriano (1385-1427). At the Department of Physics of the University of Bologna, in collaboration with the National Gallery of Bologna and the "Opificio dele Pietre Dure" restoration center in Florence, was performed an X-ray investigation of the inner structure of two small (20cm x 7 cm) painted "tablets", made of wood, and recognised as an artwork of Gentile da Fabriano, an important painter of the XIII century. Different techniques were used: conventional film radiography, digital radiography and computed tomography, the latter two with innovative equipment of the Department of Physics in Bologna.
An important result was achieved with the intensified fiber optics scanner. A quality close to that of a conventional film was obtained with estimated two order of magnitude less dose.
