Abstract
Image quality of E-speed film processed in four rapid chemistry solutions was evaluated
and compared to that of D-speed film. One-hundred-twenty films (60 E-speed and 60
D-speed) were exposed with the use of a quality-control phantom and processed in four
different rapid solutions. The images were evaluated for speed, contrast, fog and
base, resolution, and granularity, and the useful lifetime of the solutions was determined.
E-speed film processed with rapid chemistry produced images equal in quality to D-speed
film in the range tested (70 to 90 kVp). Fog and base levels of E-speed film were
greater than those of D-speed film. The resolution and grandularity of the images
were equal and were judged adequate in both film types, regardless of the chemistry
used. Rapid processing solutions were found to have a 10% to 15% shorter useful lifetime
with E-speed film than with D-speed film. The processing of E-speed film in rapid
chemistry is recommended for emergency care and endodontics.
