ACR CT Accreditation Phantom GAMMEX 464

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.

Available as package only: Part #464-PKG

Includes: Phantom, Stand Software and Carrying case.

Care of the Gammex Model 464 ACR CT Accreditation Phantom

Congratulations on your purchase of the Gammex Model 464 ACR CT Accreditation Phantom. The Model 464 has been designed to provide years of stable, trouble-free use. It is constructed from a special composite material designed to mimic water in a CT scanner with none of the troubles associated with a water phantom.

Conditions of use:

The Model 464 phantom should be used at temperatures between 15 and 25 ° C (optimally 20°C). As is true for all materials, thermal expansion and contraction will alter the density of the phantom, which will cause slight shifts in the CT numbers of critical elements.

The phantom should be stored and used at the same temperature. If the phantom has been stored at a different temperature, allow it to normalize at the rate of 1 hour for each 1°C of difference.

Storage Conditions:

The phantom should not be subjected to conditions of extreme cold or heat. A brittle fracture could occur with sudden thermal shock from cold to warm conditions. Under very hot conditions, the phantom materials may soften and deform.

Prolonged storage under unusually high humidity conditions may result in moisture absorption. This is typically only on the surface and is reversible. Store your phantom in a dry location with controlled humidity to avoid this concern.

Storage of the phantom in bright light conditions will cause a shift in color. Such discoloration does not affect the functional properties of the phantom in any manner. To avoid discoloration, store the phantom in a light-tight enclosure.

As with all precision instruments, avoid drops, impacts, and vibration during use, transport and storage. A convenient way to decrease the possibility of damage is the Gammex Phantom Stand and Carrying Case. Damage caused by misuse is typically not covered under warranty.

Cleaning:

The Model 464 phantom can be cleaned with a mild detergent followed by a water rinse and wiping dry. Adhesive tape residue can be removed by wiping with mineral oil, followed by an alcohol rinse and wiping dry. Solvents and abrasive cleaners should not be used.

Storage/Use Conditions:

Use temperature: 15 - 25°C
Storage temperature: 0 - 40°C
Storage and use relative humidity: 8 - 70%
