Community-acquired pneumonia is diagnosed by clinical features (e.g., cough, fever, pleuritic chest pain) and by lung imaging, usually an infiltrate seen on chest radiography.
What is radiography?
An imaging technique called radiography uses X-rays, gamma rays, or other ionizing radiation along with non-ionizing radiation to see an object's internal structure. Medical radiography ("diagnostic" and "therapeutic") and industrial radiography are two examples of radiography applications. Airport security employs similar procedures (where "body scanners" generally use backscatter X-ray). In traditional radiography, a beam of X-rays is produced by an X-ray generator and directed toward the object to make an image. Depending on the object's density and structural make-up, the amount of X-rays or other radiation that is absorbed by it varies. A detector is placed behind the object to catch the X-rays that travel through it (either photographic film or a digital detector).
