Part 2 book “Chesneys' radiographic imaging” has contents: Presentation and viewing of radiographs, storage and archiving of exposed film, the radiographic image, the influence of exposure factors, image quality control, the image intensifer, lens systems and image distributors, . And other contents. | Chapter 14 Presentation and Viewing of Radiographs Types of information Identification (essential information) Technical Miscellaneous Methods of recording information Opaque letters and legends Actinic marking Perforating devices Identification of dental films Dental mounts Final presentation of the radiograph Viewing equipment Colour temperature High-intensity light spot Specialized illuminators No radiograph is complete unless it has been correctly identified with sufficient patient details imprinted upon it. The need not only for sufficient, but accurate identification can never be stressed enough. Without it, a radiograph is useless. Besides being dangerous practice, the medicolegal implications which may arise if a poorly or non-identified radiograph is wrongly associated with a particular patient should be a sobering thought for any radiographer. Providing as much information as possible minimizes the risk of uncertainty over identification, and can help to speed up the sorting process. It should be the responsibility of the radiographer who takes the film to ensure that the radiograph includes all the necessary information. Careful checking of each radiograph is therefore essential. There is no exception to this rule. All information should be photographically imprinted upon the film by the methods that we describe later, or be put there during radiographic exposure. Adding details by hand after the radiograph has been processed is a sloppy method which only encourages error. Types of information Identification (essential information) (1) Full name.
