MODEL 141 AND 141H HIGH CONTRAST RESOLUTION TEST TOOLS

High Contrast Resolution Test Tools Model 141
Model 141H
An important measure of your fluoroscopy system is its high contrast resolution.  This test is used to assess the resolving   power of your system and can be done easily with the Gammex 141 and 141H High Contrast Resolution Test Tools.  Both the 141 and 141H consist of eight patterns of copper wire mesh in a pie shape.  Each is labeled with lead numbers for easy visualization.  The difference between the 141 and the 141H is the mesh.  The 141 is used for standard radiographic systems with resolutions between 16 and 60 mesh.  The 141H is designed and recommended for systems with high resolution such as those used in cardiology suites, where resolution is between 60 and 150 mesh.
