Definition for Radiography
From Biology Forums Dictionary
Radiography is the use of X-rays to view a non-uniformly composed material (i.e. of varying density and composition) such as the human body. A heterogeneous beam of X-rays is produced by an X-ray generator and is projected toward an object. The density and composition of each area determines how much of the ray is absorbed. The X-rays that pass through are captured behind the object by a detector (either photographic film or a digital detector). The detector gives a 2D representation of all the structures superimposed on each other.
