The company received business advice and financial support from the ESA business incubation centre in Prague. “During this process it became clear that the work was executed layer by layer by Raphael, without the aid of his workshop assistants and apprentices,” says Jiří Lauterkranc, an art restorer and co-founder of InsightART. Spectral X-ray images reveal previously hidden layers of the painting. The artwork was scanned in great detail – from the foundation layers to the final glazes, revealing the internal structure of Raphael’s painting in detail. “While the standard X-ray machine only creates a black and white image, the RToo scanner provides ‘colour’ – or spectral – X-ray images, which allow the materials to stand out on the basis of their elemental composition,” he says. “This technology – which is also used to measure radiation at the International Space Station – is capable of detecting and counting single photons, as well as establishing their exact wavelength,” says Josef Uher, chief technical officer of InsightART. The machine uses a particle detector developed at CERN, the European laboratory for particle physics, that was repurposed for space exploration and manufactured by the Czech company ADVACAM. InsightART’s robotic X-ray scanner had earlier been used to identify a previously unknown painting by Vincent van Gogh. This has now been further supported by InsightART, a start-up company based in the Czech Invest-operated ESA business incubation center in Prague, which uses cosmic detector technology to examine artworks. That Raphael was in fact the creator of the masterpiece has been confirmed by expert studies from around the world as well as an international advisory board.
