Mammography Phototimer Consistency Testing Slabs.
Computerized Imaging Reference Systems, Inc! Better than PMMA for AEC calibration

CIRS Phototimer Consistency Testing Slabs are designed for precise assessment of AEC system performance in accordance with American College of Radiology and MQSA recommendations. BR-12 (47% glandular / 53% adipose) is most commonly used but other glandular equivalencies are available. Unlike acrylic, these testing slabs are manufactured with very tight thickness tolerances and more accurately simulate real breast tissue over the range of energies used in mammography.

Mammography Artifact Evaluation Phantom






The American College of Radiology and MQSA recommend a uniform 4 cm thick "high grade" cassette sized phantom for evaluation of mammography artifacts as it is often difficult to identify artifacts based on clinical or standard phantom images.

CIRS has designed two phantoms to meet these recommendations. The small phantom measures 18 x 24 x 4 cm thick and the large phantom measures 24 x 30 x 4 cm thick.

Both are made from tissue equivalent BR-12 with a thickness tolerance of .01 mm and all phantoms are image tested and carefully screened for homogeneity and impurities. Other glandular equivalencies are available upon request.
