Fusion images

Here is a concise and clear explanation of the concept of fusion images combining visible light and X-rays; I hope it is easy to understand:

The fusion of visible light and X-rays represents a combination of external appearance and internal structure. Visible light reveals surfaces, colours and shapes. X-rays make internal structures visible. This is why fusion images using X-rays are found in astronomy, medicine, art and restoration, materials research, archaeology, and security applications such as luggage screening. Fusion images arouse interest because they not only show what something looks like, but also reveal what lies hidden beneath. Alongside the reality visible to the naked eye, a deeper level of reality becomes apparent. My professional career as a radiologist is characterised by the ability to make things visible that must remain hidden from the eye. As an artist, I can use fusion images to give photography a deeper dimension through unexpected transparencies, overlays and contrasts.
