New computed radiography processing condition for whole-spine radiography.

Computed radiography (CR) has many advantages compared with conventional radiographs, especially in image processing. Although CR is being used in chest radiography and mammography, it has not been applied to spine imaging. The purposes of this study were to formulate a set of new CR processing parameters and to test whether the resultant whole-spine radiographs visualized the spine more clearl...

New dimensions in chest radiography.

Traditionally in the United States, large size chest x-ray film examinations are made with 14 x 17 inch ifims in 15 x 18 inch cassettes. When a survey minifilm reveals a questionable disease process, large films are ordered for further study. This film has become the accepted size through years of routine practice.
