RD/FL Contrast Resolution Test

Send Your Inquiry:

The RD/FL Phantoms are an easy to use tool to quickly assess the general radiographic and fluoroscopic image quality and performance of a standard imaging system. The Model L647 phantom has three various shaped mesh patterns ranging from 20 to 100 lines per inch. Surrounding the Mesh Pattern are four Low contrast targets of varying diameters (2 mm, 4 mm, 6 mm and 8 mm). The Model L656 RD/FL Digital Test Tool has a centered contrast scale and a line pair resolution insert that allows simultaneous evaluation of resolution, contrast and density uniformity. The ability to measure contrast and resolution in one exposure allows the QC Technologist, service engineer, or medical physicist to quickly determine whether or not the system is working correctly. When used daily, the RD/FL test tools will also easily identify trends that may be an indication of image degradation, typically caused by slight changes in kVp or mAs.
