RaySafe Pro-Mam Accrediation Phantom

The Mammography Accreditation Phantom is designed to meet the Mammography Quality Standards Act (MQSA) and the American College of Radiology (ACR) Quality Control Programs for diagnostic testing. It is used for Full-field Digital Mammography (FFDM) machines.

This phantom is intended for use as an integral part of the Mammographic Quality Control Program. It helps you to quickly and easily perform routine testing to evaluate the overall imaging performance of your mammographic system.

Regular quality control performed with the RaySafe Pro Mam Accreditation Phantom allows you to detect any changes in imaging quality, enabling you to maintain the system so it remains at peak performance.

This phantom was designed to test the performance of a mammographic system by a quantitative evaluation of the system’s ability to image small structures, important in the early detection of breast cancer. Objects within the phantom simulate fibrous lesions, microcalcifications, and tumor masses. Sizes range from what should be visible on any system, to objects which would be challenging to detect even for the best mammography units.

Key Features 

• Complies with ACR phantom specifications and accreditation program/quality control (QC) requirements
• Tests the performance of a mammographic system and its ability to image small structures similar to those found clinically
• Contains test objects to simulate indications of breast cancer, punctuate calcifications, tissue fibrillar extensions in adipose tissue, and tumorlike masses
• Ideal for monitoring the overall performance of your mammographic imaging system
• Equivalent in X-ray attenuation to a 4.2 cm compressed "average" breast
• Helps ensure optimum image quality and peak performance of the mammographic system
• Essential for MQSA compliance

Note: The phantom is made of a 7.25 mm (0.29 in.) wax block insert containing 16 sets of test objects, a 33.75 mm (1.33 in.) thick acrylic base, and a 3 mm (0.12 in.) thick cover.

The phantom approximates a compressed breast of average glandular/adipose composition.
Included in the wax insert are five aluminum-oxide (Al2O3) specks that simulate microcalcifications.

Six different nylon fibers simulate fibrous structures and five different size lens-shaped masses simulate tumors.

Each phantom includes a 4 mm (0.16 in.) thick, Ø 10 mm (0.39 in.), 6 g (0.2 oz) acrylic contrast test disk, and a magnifying glass
