Radiografia-X de pintura

: fundamentos radiológicos, parâmetros radiográficos e potencialidades interpretativas

Abstract

This study aims to develop the knowledge about the application of X-radiographs to easel painting, focusing on those with wood and canvas supports. An historical perspective is drawn, from the discovery of X-rays by Wilhelm Röntgen, through the following radiological and radiographic impact, to the implementation in the field of art works. It is described the radiological basis involved in this type of examination, concerning the nature of electromagnetic radiation, the way X-rays are produced and the resultant phenomena of its interaction with matter. Every radiographic factor is evaluated such as the nature of the radiation, the instrumental parameters, geometrical and placements issues or the inclusion of additional structures, and then proceed to the systematic description of its impact on image quality, whether in analogic film, as on digital support. In the reading component of the data, it is outlined a specific methodology of image interpretation, being described and explored specific case studies that illustrate the ability to supply new information on easel painting, by this non-destructive exam.
