Photographic processing produces a permanent film image that is the final mammogram. In DM, x-ray photons strike the digital detector, and the photons are absorbed by a phosphor material.

WebSilver is a common component of most historical photographic processes. Silver mirroring is a natural deterioration, inherent within silver-containing photographic material. Silver is affected by oxidizing agents and silver ions are produced. Once these ions are produced, they can migrate through the gelatin layer, towards the support (Weyde 1954). Webthe silver atom reverts to a silver ion. When this occurs, a stable photographic latent image can be formed. 24 The num ber of silver atoms, n, required to form a stable silver cluster is between 3 and 5. Somewhere between 6 and 30 absorbed photons are needed to form this stable latent image. 5 The steps involved in this
