ART X-RAY from NTB
X-ray technology for Art and History
Art museums and galleries often face the task of conserving and restoring paintings. It is important for restorers to know the location and extent of hidden damages, as this has an impact on the restoration concept. An important examination method here is x-raying: X-rays reveal hidden structures and provide valuable knowledge about the structure and changes in the artwork.
X-ray technology is also used in research and authentication. Painting techniques and pentimenti (changes to the painting during the creation phase) are recognized and analyzed on the basis of the x-ray images. Sometimes the x-rays even reveal finished paintings that were later painted over with the painting visible today.
But not only paintings are x-rayed: other objects such as sculptures, antique furniture and archaeological finds also hold secrets. What is the internal structure of a sculpture? What technical joints were used to hold a piece of furniture together? How does the mechanism of an old toy work? These are some of the questions that can be answered by x-ray examination.
Our x-ray ART X-RAY systems, especially designed for full-digital x-ray examination of large format paintings, sculptures and other historical objects
The problem with conventional x-ray systems is that they can only ever expose relatively small x-ray images. Several x-ray images must be taken of larger objects, each of them shows only a small section. And since the exposure position must be changed for each individual x-ray image, the amount of work increases exponentially with the size of the object.
In contrast to other x-ray systems, our ART X-RAY system works according to the scanning principle: With a high-resolution x-ray linescan camera the respective object is scanned lengthwise. One single pass creates a very large x-ray image. This drastically reduces the amount of work, e.g. for the examination of a large format painting. The objects are always scanned without contact and leave no traces or even damage to the artwork. You can find more detailed information on the recording technique in the description of the system
Renowned museums such as the Städel Museum in Frankfurt and the Belvedere Palace in Vienna already work with our ART X-RAY systems. Please have a look at our references.
