“…The X-ray imaging analysis was carried out at the CCR in a shielded 6 × 5 m 2 room where the fixed apparatus developed in the framework of the neu_ART project is in operation. The system is composed mainly of a General Electric Eresco 42MF4 X-ray source, a rotating platform of about 1.6 m in diameter on which the object is placed allowing the acquisition of multi-angle images, and a linear X-ray detector [19][20][21]. The X-ray source has a focal spot size of 3 mm (EN12543) and a 900 W maximum power that means a maximum current of 4.5 mA at the highest voltage of 200 kV, increasing to a maximum of 10 mA at lower operating voltages.…”

“…Due to the great variety of materials and dimensions of artworks in the cultural heritage field, the apparatus at CCR was purposely customized to be more flexible than medical and industrial CT. Developed in the framework of the neu_ART project involving the National Institute for Nuclear Physics (INFN), the Physics Department of the University of Torino, and CCR [18,19], the basic version was designed to perform, in a short time and with a sufficiently good resolution for restoration purposes, Digital Radiographies (DR) of large objects, up to 4 m × 3 m [20]. Moreover, the DR apparatus was integrated into a more complex system that can be used for the computed tomography of voluminous objects up to 2.5 m in height and 2 m in width [10,21,22].…”

Diagnostic physical methods are increasingly applied to Cultural Heritage both for scientific investigations and conservation purposes. In particular, the X-ray imaging techniques of computed tomography (CT) and digital radiography (DR) are non-destructive investigation methods to study an object, being able to give information on its inner structure. In this paper, we present the results of the X-ray imaging study on an ancient Egyptian statuette (Late Period 722–30 BCE) belonging to the collection of Museo Egizio in Torino and representing an Egyptian goddess called Taweret, carved on wood and gilded with some colored details. Since few specific studies have been focused on materials and techniques used in Ancient Egypt for gilding, a detailed investigation was started in order to verify the technical features of the decoration in this sculpture. Specifically, DR and CT analyses have been performed at the Centro Conservazione e Restauro “La Venaria Reale” (CCR), with a new high resolution flat-panel detector, that allowed us to perform tomographic analysis reaching a final resolution better than the one achievable with the previous apparatus operating in the CCR.

At present, the use of non-destructive, non-invasive X-ray-based techniques is well established in heritage science for the analysis and conservation of works of art. X-ray fluorescence (XRF) plays a fundamental role since it provides information on the elemental composition, contributing to the identification of the materials present on the superficial layers of an artwork. Whenever XRF is combined with the capability of scanning an area to provide the elemental distribution on a surface, the technique is referred to as macro X-ray fluorescence (MA-XRF). The heritage science field, in which the technique is extensively applied, presents a large variety of case studies. Typical examples are paintings, ceramics, metallic objects and manuscripts. This work presents an uncommon application of MA-XRF analysis to furniture. Measurements have been carried out with the MA-XRF scanner of the INFN-CHNet collaboration at the Centro di Conservazione e Restauro “La Venaria Reale”, a leading conservation centre in the field. In particular, a chinoiserie lacquered cabinet of the 18th century and a desk by Pietro Piffetti (1701–1777) have been analysed with a focus on the characterisation of decorative layers and different materials (e.g., gilding in the former and ivory in the latter). The measurements have been carried out using a telemeter for non-planar surfaces, and with collimators of 0.8 mm and 0.4 mm diameter, depending on the spatial resolution needed. The combination of the small measuring head with the use of the telemeter and of a small collimator has guaranteed the ability to scan difficult-to-reach areas with high spatial resolution in a reasonable time (20 × 10 mm2 with 0.2 mm step in less than 20 min).

“…A scanner suited for the digital radiography of large paintings has been developed at "La Venaria Reale", the restoration centre in Turin (Italy) by the research group of INFN (National Institute of Nuclear Physics) and University of Turin [20,21]. But, in this case, the scanner is fixed because it is devoted to the use by restorers at the centre.…”

A scanner for in situ X-ray radiography of large paintings: the case of “Paolo and Francesca” by G. Previati

A scanner for digital radiography of large paintings has been designed and developed, aimed to in situ performances. We report here the application to “Paolo and Francesca” ($$260 \times 230 \,\hbox {cm}^{2}$$ 260 × 230 cm 2 ), masterpiece by the Italian divisionist painter Gaetano Previati (1909). The scanner has given the whole radiography in 1137 X-ray shots, which were corrected for X-ray inhomogeneities and finally processed, minimizing the visual impact of the frame structure. The original version of the painting has been brought to the light, and it appears to be a further step in the evolution of the theme frequently experienced by the artist.
