Non-invasive imaging techniques

Definition

Non-invasive imaging techniques refer to methods used to visualize and analyze the structure and condition of artworks and artifacts without causing any damage to them. These techniques are crucial in art conservation as they allow conservators to gather information about the materials, layers, and underlying issues of a piece while preserving its integrity. By employing these methods, professionals can make informed decisions about the necessary conservation treatments and monitor changes over time.
