1.1 Introduction
The R/F QC Phantom was designed to give diagnostic radiologic technologists an easy method for
evaluating the image quality and performance of diagnostic radiographic and fluoroscopic imaging
systems. Its design is based on the same philosophy as the Mammography Accreditation Phantom: ease
of use, simplicity of evaluation, and the ability to provide useful quality control information.
The R/F QC Phantom provides a means for evaluating the constancy of the imaging system, rather than
for doing a thorough evaluation. For a standard R/F system, no more than 5 minutes should be required
to complete the suggested protocol. Additionally, the Phantom includes two low contrast squares to be
used to verify that the brightness and contrast controls of your fluoroscopic monitor are optimally
adjusted.
It is suggested that the Phantom be imaged on all radiographic and fluoroscopic equipment at least
monthly. If feasible, a weekly or even daily frequency is preferable. If used daily, the Phantom will allow
the technologist to determine very quickly whether or not the equipment is functioning well and if it is
ready for clinical use before any patient studies begin.
It is assumed that a responsible technologist is performing the evaluation, and that the guidance of a
trained Quality Control Technologist, Service Engineer or Medical Physicist is available when needed.
