Diagnostic Test Tools
Model L-600 Fluoroscopic Alignment Device                                   Model L-600
 The Ludlum Fluoroscopic Beam Alignment device
 consists of an aluminum plate with 4 sliding brass strips set in
 recessed channels. The strips define the border or visible
 area of the image receptor. A plastic overaly prevents any
 vertical displacement of the brass strips. Holes drilled in
 half inch intervals are filled with higher density material for
 visibility through the brass strips. The device when placed
 in the center of the image receptor is designed to correct or
 optimize fluoroscopic collimation.

 Any portion of the fluoroscopic field that falls outside the
 image receptor does not contribute to the useful image and
 can lead to unnecessary exposure to the patient. This very
 simple but critical measurement will identify a misaligned
 fluoroscopic system.

 Dimensions: 9” x 9” x 5/8”
 Weight: 5 Lbs.

                                                                                     Part Number: 99-9406

            Model L-777 CR/DRr Test Tool                                    Model L-777
 The Ludlum CR/DR Test Tool is designed for the evaluation
 of the newer filmless digital CR ( Computed Radiography)
 and DR (Digital Radiography) imaging systems.

 The CR/ DR Test Tool incorporates a variety of testing
 parameters that, when used daily, tracks Geometry (region
 of interest) Symmetry, Line Pair Resolution, as well as,
 Low and High Contrast performance. Measurements of the
 various targets allow for evaluation of both the monitor and
 printed film image. The CR/DR tool will become a valuable
 asset to the QA Technologist and the Medical Physicist when
 trying to determine the source of an image quality problem
 or complaint.

 The large 14” x 17” size make it ideal for quick checks on
 automated chest systems.

 Dimensions: 14” W x 17” H x 0.5” D
 Weight:       7 Lbs.
 Converging Line Pair Test Pattern                                                   Part Number: 99-9412
