areas on the radiograph. The edge definition or detail is not present because<br />
<strong>of</strong> certain factors or conditions which exist in the imaging system.<br />
In review, it is entirely possible to have radiographs with the following<br />
qualities:<br />
■ Low contrast and poor detail<br />
■ High contrast and poor definition<br />
■ Low contrast and good definition<br />
■ High contrast and good definition<br />
One must bear in mind that radiographic contrast and definition are not<br />
dependent upon the same set <strong>of</strong> factors. If detail in a radiograph is originally<br />
lacking, then attempts to manipulate radiographic contrast will have no effect<br />
on the amount <strong>of</strong> detail present in that radiograph<br />
