The WHO manual of diagnostic imaging: radiographic technique and projections
Overview
The positioning of the patient is illustrated with a computed animation technique, showing one male and one female patient that are meant to represent all ethnic groups in the world. Reasonable cassette-screen-film combinations are suggested, as well as exposure values, which have to be adjusted to local conditions. Each page contains a short recommendation of how to handle the patient, and it should, as a rule, be possible to perform the examinadon of the patient only following tl1e illustrations and instructions on the relevant page. An acceptable, usually normal, resulting X-ray image is shown. FoUowing the instructions, the result will be a standard projection that is easily repeated for comparison and easily understood by physicians and others trained to interpret radiographs.
