In 1895 W.C. Roentgen invented roentgenograms, which today are
simply referred to as x-rays or radiographs. Although x-rays
have evolved over the years, the principle remains the same -
except - today's techniques utilize only a fraction of the x-ray
dose required in the early days of radiology. Truly, x-ray
technology is the 'workhorse' of fundamental diagnostic imaging.
Testing is fast, easy, and painless. Radiographs are produced by
means of a source that radiates x-rays through a particular body
part (e.g. spine). As the x-rays pass through the body they are
weakened by the many types and levels of tissue encountered.
That is why bony structures appear more prominently (e.g.
whiter) than soft tissue - bone is denser and absorbs a greater
amount of radiation. The energy is directed into a film cassette
that has been placed into a receptacle under/behind the targeted
body part. The film is exposed and developed in much the same
manner as a photograph. AP (Anterior/Posterior) X-Ray of Lumbar
