Evaluation of a new x-ray film with reduced crossover. 1979

G U Rao, and P P Fatouros

The improvement in MTF that can be obtained by the reduction of crossover exposures is evaluated using an experimental film supplied by the 3M Company (3M XUD). It was found that image resolution, as measured by the equivalent passband (2 integral of infinity 0 [M(f)]2df), of 3M Trimax 8 screens when used with the experimental 3M XUD film was 2.9 c/mm as compared to 1.8 c/mm when used with a conventional double coated film such as Kodak Ortho G or 3M XD. On the other hand, system speed with 3M XUD film was only 1.6 mR-1 as compared to 3.2 mR-1 with 3M XD film and 2.4 mR-1 with Kodak Ortho G film. These findings were substantiated by phantom studies as well.
