The Gammex 464 ACR CT Phantom is designed to be an integral part of the American College of Radiology (ACR) CT
Accreditation Program. This voluntary program provides physicians with an opportunity for a comprehensive peer review of
their CT facility, personnel qualifications, image quality and quality assurance programs. CT accreditation encourages
patient’s confidence and demonstrates your commitment to quality healthcare to payers, regulatory agencies and employers.
The ACR CT Accreditation Phantom can be used for initial QA assessment and routine monthly QA testing to help ensure
that patients are receiving the lowest possible CT dose. Solid Water ?construction makes for a convenient, physically
stable test device that provides reproducible results over time. The phantom consists of four modules designed to examine
a broad range of scanner parameters. It features white scribed markings on the axial, coronal and sagittal axis, and HEAD,
FOOT and TOP markings to ensure proper alignment. The optional phantom base, Gammex 464-STND (shown above
with the phantom) provides stability, makes alignment easier and features built-in leveling devices. The optional
analytical software, Gammex 464-ACTS provides automated data analysis for the ACR acrreditation CT Phantom 464.
