Model L-647 RD/FL Contrast/Resolution Test Tool

The RD/FL Test Tools are used to quickly assess the image quality and performance of diagnostic radiographic and fluoroscopic imaging systems. The ability to measure contrast and resolution in one exposure allows the operator to quickly determine whether or not the system is working correctly.

The Model L-647 has center quadrants numbered to correspond to the lines of wire mesh per inch (40, 60, 80, and 100). The tool also has four low-contrast targets of varying diameters (2, 4, 6, and 8 mm), a contrast square, two monitor adjustment squares, and a copper attenuator to simulate the attenuation of a small adult.
