The process was led by institutions such as the <strong>B\u00f3veda Verde, the Albertinum and the Galer\u00eda de los Maestros Antiguos<\/strong>, who sought to deepen the creative and restorative processes of their artistic heritage. <\/p>\n\n<h2 class=\"wp-block-heading\">D\u00dcRR NDT technology<\/h2>\n\n<p>Various tools from the German company D\u00dcRR NDT were used to carry out these studies.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Model HD-IP<\/strong> high-definition imaging plates, which are placed behind the artwork to capture the X-ray image.<\/li>\n\n\n\n<li>One scanner <strong><a href=\"https:\/\/www.duerr-ndt.com\/products\/computed-radiography\/hd-cr-35-ndt.html\" target=\"_blank\" rel=\"noreferrer noopener\">HD-CR 35 NDT<\/a><\/strong>The HD-CR 35 NDT scanner is used to &#8220;read&#8221; the imaging plates (HD-IP) after they have been exposed to X-rays. The scanner digitizes the information stored on the plate and creates a digital image file on the computer.<\/li>\n\n\n\n<li>The analysis software <strong><a href=\"https:\/\/inspenet.com\/en\/video-tv\/durr-ndt-digital-radiography-panndt-2025\/#:~:text=D%2DTect%20X%3A%20adquisici%C3%B3n%20de%20im%C3%A1genes%20radiogr%C3%A1ficas%20optimizadas\" target=\"_blank\" rel=\"noreferrer noopener\">D-Tect X<\/a><\/strong> to scan in great detail the internal structures of the parts.<\/li>\n<\/ul>\n\n<p>By using these tools they were able to cut the analysis time in half, from half a day to a quarter of a day. In addition, by using extremely thin imaging plates, it is possible to <strong>examine fragile or oddly shaped objects<\/strong>, such as the rhino horn cup, with great precision. <\/p>\n\n<p>On the other hand, by stitching together several digital radiographs, they can create a <strong>highly detailed, panoramic image<\/strong> (in TIF format) that shows the <strong>finest details<\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">What can be discovered with this technology?<\/h2>\n\n<p>Thanks to computerized radiography, it was possible to detect <strong>tears, loss of color and seams in canvases<\/strong> that previously went unnoticed. In the case of wooden panels, it was possible to identify <strong>assembly techniques<\/strong> such as the use of dowels or gluing, even with variations of millimeters. <\/p>\n\n<p>One of the most striking investigations was on copies of <strong>Rembrandt&#8217;s The Burial of Christ<\/strong>, where it was observed how <strong>some details were added later<\/strong>, altering the original composition. These observations make it possible to trace technical, material and stylistic changes that enrich the understanding of the works. <\/p>\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"677\" src=\"https:\/\/cdn.inspenet.com\/rembrandt-entierro-cristo-radiografia-computarizada-1024x677.webp\" alt=\"Computer X-ray of Rembrandt: The Burial of Christ (copy), with invisible tears.\" class=\"wp-image-314412\" srcset=\"https:\/\/cdn.inspenet.com\/rembrandt-entierro-cristo-radiografia-computarizada-1024x677.webp 1024w, https:\/\/cdn.inspenet.com\/rembrandt-entierro-cristo-radiografia-computarizada-300x198.webp 300w, https:\/\/cdn.inspenet.com\/rembrandt-entierro-cristo-radiografia-computarizada-768x508.webp 768w, https:\/\/cdn.inspenet.com\/rembrandt-entierro-cristo-radiografia-computarizada-624x412.webp 624w, https:\/\/cdn.inspenet.com\/rembrandt-entierro-cristo-radiografia-computarizada.webp 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Rembrandt, The Burial of Christ (copy) with a large tear, which was invisible during repairs.
