Mammographic Accreditation Phantom
The required standard for image quality evaluations.
Model 015
Meet
MQSA requirements.
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.
Tissue-Equivalent
Phantom for Mammography
A Refined Quality Assurance
Tool for Today's Advanced Imaging Systems.
Model
011A
Proven simulation technology enables the use of tissue-equivalent, realistically-shaped phantoms for mammographic quality assurance.
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
Model
013
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
Model 903
The
CIRS Model 903 ACR Radiography / Fluoroscopy Phantom is designed
to be an integral part of the American College of Radiology (ACR) Radiography
/ Fluoroscopy Accreditation Program. This voluntary program provides
physicians with an opportunity for a comprehensive peer review of their
Radi-ography / Fluoroscopy facil-ity, personnel qualifications, image
quality and quality assurance programs.
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.
Nema SCA&I Cardiovascular Fluoroscopic Benchmark
Phantom
Model 901
| The
CIRS Model 901NEMA - SCA&I phantom was designed
to evaluate and standardize catheterization image quality. It
is the result of collaborative efforts between the Society for
Cardiac Angiography and Interventions and the National Electric
Manufacturers Association. The phantom specifically enables
voluntary compliance with the recently published performance
standard NEMA XR 21.
|
| The
Model 901 is manufactured from PMMA with x-ray absorption
properties similar to soft tissue at diagnostic energies. It
contains a variety of static and dynamic test targets for objective
assessment of resolution, motion unsharpness and radiation exposure.
The sectional design allows for configuration in a wide range
of thicknesses from 5cm to 30 cm simulating PA thicknesses from
infants to large adult patients.
The phantom is ideal for routine assessment of the entire imaging system. |
Mammoview
Markers 021 & 022
Simple to use and compatible with any mammography x-ray system
Model
022
Each marker is manufactured to be clearly visible on x-ray film only in the mammo-graphic energy range.
Each set of markers comes with an acrylic holding device designed to be mounted near the x-ray unit for easy access.
The CIRS Mammoview Mark-ers are quick and easy to use. Simply mount the acrylic holder near the mammogra-phy unit in close proximity to the buckey. Firm pres-sure applied to the suction cup will hold the marker in place on any smooth surface. Mammoview Markers are usable on any mammography system.
Benefits:
- Fast and simple to use.
- Meets all requirements for standardized terminology set forth by the American College of Radiology.
- For all mammography systems.
- Custom, personalized ID markers also available.
CT
CT Dose Phantom
Designed for FDA performance standard.
Model 007
Each phantom consists of two 14cm thick solid PMMA disks measuring 16 cm (head) and 32 cm (body) in diameter.
