Test Patterns Models 07-501 to 07-555 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 patteerns up to 5 LP/mm. Radiopaque numbers indicate the resoulution (in LP/mm) of each group.   Shown in Model 07-501-2000
