1.1 Specifications
Fluoroscopic Phantom, Model 07-649 is designed to meet the requirements for the NEXT* protocols.
This patient-equivalent phantom of uniform thickness consists of a 7" 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" off the tabletop. One leg is specially designed as a probe holder.
Fluoroscopic Image Quality Test Object
This aluminum disk is (2" diameter; 0.25" thick), comprised of eight low-contrast test holes (each 0.375"
diameter, and ranging in depth from 0.0063" to 0.068") and eight wire meshes (ranging from 12 to 60
wires per inch). The test object is used for the assessment of spatial resolution, and can easily be taken
on and off the phantom.
Lead Stop Plate
This 3.2 mm (1/8") plate simulates maximum attenuation, and can be used to measure the maximum air
kerma rate (free in air).
Copper Attenuation Plate
This 1.6 mm (1/16") copper filter simulates the presence of a 2 mm thick layer of barium sulfate, and can
be used to measure the air kerma rate (free in air).
This phantom is now required in order to comply
with QC tests recommended in the ACR's Barium
Enema QC Manual.
*NEXT (Nationwide Evaluation of X-Ray Trends is a committee of The Conference of Radiation Control Program Directors (CRCPD)
that oversees quality control procedures for diagnostic radiology. They issue procedure protocols and guidelines for imaging
modalities.
