CIRS 010 and CIRS 011A are tissue-equivalent, anthropomorphic phantoms
designed to test performance of any mammographic system. Simulated
calcifications, fibrous ducts, and tumor masses are embedded into the phantom as
test objects. Test objects range in size to allow system checks at varying
levels of difficulty.
CIRS mammographic phantoms include a removable 0.5 cm adipose-equivalent
tissue layer, have compressed thicknesses ranging from 4-6 cm, consists of
various glandular compositions and are realistically shaped. Standard Model 010
and 011A configurations are composed of 30% glandular/ 70% Adipose, 50/50
glandular and adipose, or 20/80 glandular and adipose. In addition, CIRS can
manufacture any glandular/adipose combination from pure gland to pure fat.
Model 010 and 011A address all desirable features of breast-equivalent
phantoms as described by NCRP Report No. 95. Phantoms are realistically shaped
and are designed to mimic tissue of average firm breast. Breast detail
components closely simulate the radiographic properties and shapes of normal and
pathological breast structures. Phantoms can be used to evaluate radiation dose
and image quality. The subjective assessment of detail visibility is easy to use
for routine clinical assessment, while densitometry analysis provides necessary
accuracy for laboratory work. The phantoms may be used for screen-film
mammography or digital mammography.
