       Focal Spot Test Star Patterns.       
Pro-Project! "Pro-Star" Test Patterns for Focal Spot Size can be determined by observing the regions of blurring which occur when the pattern is radiographed by an x-ray source of finite dimensions. Radiation from different areas of the focal spot will cause a periodic blurring of the pattern due to penumbra effects. Knowledge of the geometric factors, and the distance from the center of the pattern to the region where blurring occurs, will permit the calculation of the focal spot size with the same accuracy as measurements made with a pinhole camera.

       Line Pair / Resolution Test Phantoms.       


Leeds Test Objects! Resolution Test Patterns by LEEDS.

Manufactured since 1955, these test patterns have become world renowned as a clinical standard for establishing the correct operating performance of X-ray machines following their adoption for clinical use by the U.K. Health Service (NHS) in 1973 and as a testing protocol by the U.K. Hospital Physicists' Association (I.P.E.M.) in 1979.
They are used worldwide to ensure the safety and image quality of X-ray, MRI, nuclear medicine and radiotherapy imaging systems.

These test patterns are designed for quick quantitative assessments of the limiting spatial resolution of an X-Ray system. The line pair patterns consist of a thin foil of Lead sandwiched between plastic plates. In the foil, linear slits are cut with a range of widths, these alternate with linear bars of the foil of equal width. One slit and one bar is referred to as a line pair, and the width of each group of lines is specified in terms of the number of line pairs per mm (LP/mm). The observer counts the number of groups in which he can resolve the slits from the bars and as such can determine the resolving capability of the x-ray system in terms of LP/mm. A wide range of pattern designs is available with varying ranges of LP/mm and foil thicknesses.
