CDRH Fluoroscopic Phantom

?. Conforms to Center for Devices and??Radiological Health (CDRH)??specifications

?. This phantom is now required in order to comply with QC test?recommended in the

??? ACR’s Barium Enema QC Manual

?. Recommended in AAPM Report No. 60, “Instrumentation Requirements??of Diagnostic

??? Radiological Physicists”

?. Optimized for both under- and over-table fluoroscopic tubes

?. Compact, and easy to use

?The CDRH Fluoroscopic Phantom can help reduce fluoroscopy doses and improve image quality. The Nationwide Evaluation of X-Ray Trends (NEXT*) fluoroscopy protocol has been issued to provide guidelines for quality control procedures for diagnostic fluoroscopy. In order to perform these procedures, a suitable phantom was developed: the CDRH Fluoroscopic Phantom.

In a survey of fluoroscopic facilities for the NEXT program, it was determined that a substantial proportion of facilities could not visualize low-contrast test objects; this strongly suggests image quality problems.

Measurements for this survey were performed using the Model 07-649 CDRH Fluoroscopic Phantom.

In addition to air kerma rate (free in air) measurements, imaging performance was assessed using the Fluoroscopic Image Quality Test Object (included with phantom).

1 The phantom also contains a lead stop plate and copper attenuation plate.

This patient-equivalent phantom of uniform thickness consists of a 7 inch thick acrylic block, one Fluoroscopic Image Quality Test Object, one lead stop plate and one copper attenuation plate.

The base of the phantom is comprised of two type-1100 aluminum plates, each 2.3 mm thick.

The phantom has four lead beads embedded on top, to be used as collimation orientation points. It stands on two legs, approximately 4 inches off the tabletop.

One leg is specially designed as a probe holder
