X-Ray Test Patterns for Measuring Resolution. The choice of pattern depends on the specific application. The sector test patterns are 0.4°, and the group test patterns have varying numbers of line pair groups. Lead thicknesses are limited by the resolution, with a maximum thickness of 0.1 mm for test patterns up to DI Diagnostic Imaging 5 LP/mm. Radiopaque numbers indicate the resolution (in LP/mm) of each group.
07-501 and 07-555 X-Ray Test Patterns for Measuring Resolution of Image Intensifiers and Video Systems
Ultra-High Precision Test Pattern for Measuring Modulation Transfer Function
The Ultra-High Precision Test Pattern utilizes 22 groups of line pairs. Each group is indicated by the extended line above the pattern. The resolution of the individual groups can be taken from the table. Lead thickness is 0.05 mm. Pattern size is 71 x 44 mm.
