As paintings on canvas or wood are thin and flat they are convenient to radiograph, and over the past 50 years it has become almost commonplace to study them in this way (Gilardoni 1994). Paintings and drawings on paper can also be radiographed: this is considered in Chapter 5 and in this chapter. Some establishments have custom-built tables for radiographing pictures, but suitable conditions can easily be achieved with a medical X-ray set and many pictures have been examined on a hospital trolley. No harm is done to the work, and valuable, often surprising information is obtained which is useful to restorers, curators and art historians, and is also fascinating to any student of art.
