EVALUATE FFDM SYSTEM PERFORMANCE

CIRS 모델 086은 ACR 디지털 유방 촬영 (DM) 팬텀은 FFDM 시스템의 성능을 테스트하기 위해
방사선의 미국 대학 (ACR)의 후원하에 설계되었습니다. 팬텀 내의 객체는 석회화, 덕트 및 종양 질량을 시뮬레이션 할 수 있습니다.

The CIRS Model 086, ACR Digital Mammography (DM) Phantom was designed under the sponsorship of the American College of Radiology (ACR) to test the performance of FFDM systems. Objects within the phantom simulate calcifications, ducts and tumor masses. The phantom is designed to determine if your DM system can detect small structures that are important in the early detection of breast cancer.
​
The critical component of the phantom is a 7 mm thick wax insert positioned within a matching cavity milled out in a polymethylmethacrylate (PMMA) block. The total attenuation under the wax insert is matched with the 4.1 cm thick surrounding PMMA by the use of a 0.23 mm "compensator" placed under the wax insert. The wax insert contains targets as per map (Figure 2). Fibers are monofilament nylon, simulated calcifications or "specks" are made of spherical glass and the masses simulate 10% adipose - 90% glandular breast tissue.

CIRS Model 086 includes carry case, user guide and 48-month warranty.
