Mammographic Accreditation Phantom
The required standard for image quality evaluations
The Mammographic Accreditation Phantom was designed to test the performance of a mammographic system by a quantitative evaluation of the system’s ability to image small structures similar to those found clinically. Objects within the phantom simulate calcifications, fibrous calcifications in ducts, and tumor masses.
The Phantom is designed to determine if your mammographic system can detect small structures that are important in the early detection of breast cancer. Test objects within the phantom range in size from those that should be visible on any system to objects that will be difficult to see even on the best mammographic systems. The 4.4 cm thick Mammograhpic Phantom is made of a 7 mm wax block insert containing 16 sets of test objects, a 3.4 cm (approx. 1-3/8") thick acrylic base, and a 3 mm (1/8") thick cover. All of this together approximates a 4.5 cm compressed breast of average glandular /adipose composition. Included in the wax insert are aluminum oxide (Al 2 O 3 ) specks to simulate microcalcifications. Six different size nylon fibers simulate fibrous structures and five different size lens shaped masses simulate tumors.
Each Phantom includes a 4mm acrylic step wedge, operating instructions, faxitron x-ray image and magnifying lens.
A Refined Quality Assurance Tool for Today's Advanced Imaging Systems
CIRS resin material mimics the photon attenuation coefficients of a
range of breast tissues. Average elemental composition of the human
breast being mimicked is based on the individual elemental composition
of adipose and glandular tissue reported by Hammerstein.
Attenuation coefficients
are calculated by using the "mixture rule" and the Photon
Mass Attenuation and Energy Absorption Coefficient Table of J.H. Hubbell.
The CIRS Model 11A Breast Phantom contains targets that are engineered to test the threshold of the new generation of mammography machines.
Model 11A is 4.5 cm thick and simulates a 50% glandular tissue composition. The Model 11A was designed to test the performance of any mammographic system. Objects within the phantom simulate calcifications, fibrous calcifications in ducts and tumor masses. Test objects within the phantom range in size from those that should be visible on any system to objects that will be difficult to resolve on the best mammographic systems.
CIRS mammography phantoms are also manufactured in 4cm, 5cm and 6cm thicknesses with various glandular eequivalences.
The methodology and design of these phantoms was developed by Dr. Panos Fatouros and his associates at the Medical College of Virginia.

Stereotactic Needle Biopsy Training Phantom
A non-leak, tissue equivalent, compressible biopsy training phantom
This phantom closely mimics properties of the human breast. It is an ideal teaching tool and practice medium for mammographic needle biopsy procedures. Model 13 also serves as an excellent quality assurance testing device for stereotactic systems and should be used whenever a new system is installed or repaired to insure accurate needle placement.
Each solid mass can be biopsied multiple times. The phantom is constructed from a solid material so it will not leak when punctured.
Model 13 is an excellent research and development or demonstration tool
for manufacturers of mammography equipment.
Phantom Features:
- Compressible.
- Proprietary gel simulates the physical density and mass attenuation of "BR 12."
- A physical consistency similar to human tissue combined with an elastic, skin-like membrane enables palpation of embedded structures and accurately simulates needle resistance.
- Anthropomorphic shape for accurate simulation of breast compression.
- Gel will not dry out after initial needle punctures thus extending storage life.
- Contains dense masses and calcifications.
ACR Radiography Fluoroscopy Accreditation Phantom
The ACR Radiography / Fluoroscopy Accreditation Phantom can be used for initial QA assessment and routine monthly QA testing to help ensure patients are receiving the best possible x-ray examinations. The CIRS Model 903 is manufactured from PMMA equivalent epoxy that offers the same x-ray attenuation properties as acrylic with sig-nificantly greater durability.
The overall phantom mea-sures 25 cm wide x 25 cm long x 20.7 cm high and consists of three attenuation -plates, one test object plate and a detachable stand for easy, reproducible set-up. Test objects include high-resolution copper mesh targets from 12 – 80 lines per inch, two separate contrast-detail test objects.
