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-656 has three mesh patterns: 20, 30, and 40 lines per inch. At the center of the test tool is a line pair resolution pattern and a short contrast scale that allows simultaneous evaluation of the resolution, contrast, and density uniformity of the imaging chain.
