Veterinary imaging is changing rapidly from film-screen- to computer-based technologies. Even though the majority of equine imaging procedures entail assessing a radiograph on a view box, as soon as digital radiography becomes more competitive in price, it will likely replace film-based technology. Regardless of the technology used in equine practice, the generation of x-rays remains a common factor in the imaging equation. Therefore, an understanding of the production of a radiograph remains relevant for the equine practitioner. This article reviews the most commonly used portable x-ray generators in the market as well as an overview of the key concepts behind film screen radiography. It also provides a side-by-side summary of relevant specifications associated with film and screens as well as tabletop automatic film processors.
