Ludlum Medical Physics Model L-647

  RD/FL Contrast Resolution Tool

Introduction

The Ludlum 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 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.

The L-647 phantom has six pie shaped mesh patterns ranging from 20 to 100 lines per inch. Surrounding the Mesh Pattern are four Low contrast targets of varying diameters ( 2mm, 4mm, 6mm and  8mm).
