During the restoration process of a huge oil canvas (266 cm × 361 cm × 3 cm) by Agostino Bosia, a deep diagnostic campaign was carried out to characterize the original materials and those stratified over time. The activity was supported by the technologies available today in the field of conservation of the Cultural Heritage. Multispectral analyses (UV fluorescence, infrared reflectography, infrared false-colour post-production, digital radiography) associated with punctual (X-Ray Fluorescence, Fibre Optics Reflectance Spectroscopy) and microstratigraphic analyses (visible light and UV fluorescence optical microscopy and SEM–EDX) allowed to accurately reconstruct the artist's creative process and to identify the pictorial materials. The well-known analytical protocol was finally combined with Macro X-ray Fluorescence scanning technique (MA-XRF) in order to consolidate the results of the punctual, non-invasive analyses over a large area of the canvas.

“Costruzione del viadotto”：Agostino Bosia 图像执行技术中的 MA-XRF

在阿戈斯蒂诺·博西亚 (Agostino Bosia) 对巨大油画帆布 (266 厘米 × 361 厘米 × 3 厘米) 的修复过程中，进行了深入的诊断活动，以表征原始材料和随时间分层的材料。该活动得到了当今文化遗产保护领域现有技术的支持。与准时（X 射线荧光、光纤反射光谱）和显微地层分析（可见光和紫外荧光光学显微镜和 SEM-EDX）相关的多光谱分析（紫外荧光、红外反射、红外假色后期制作、数字射线照相）允许准确地重建艺术家的创作过程并识别图画材料。
