CIRS 011A乳腺模體，CIRS 011A乳腺X射線組織等效模體描述
為今天的先進成像系統提供了一個精致的質量保證工具。
CIRS 011A乳腺模體經過驗證的模擬技術可以使組織等效，逼真的模型用于乳腺攝影質量保證。
樹脂材料模仿一系列乳房組織的光子衰減系數。被模仿的人乳房的平均元素組成是基于Hammerstein報道的脂肪和腺體組織的單個元素組成。
衰減系數通過使用JHHubbell的“混合規則”和光子質量衰減和能量吸收系數表來計算。
CIRS 011A乳腺模體包含旨在測試新一代乳房X光機的閾值的目標。4.5厘米厚，并模擬平均腺體組織成分。
旨在測試任何乳房X線照相系統的性能。模型中的物體模擬鈣化，導管和腫瘤塊中的纖維性鈣化。在體模范圍內測試物體的范圍應該從任何系統上應該可見的物體到最好的乳腺攝影系統上難以解決的物體。
DESCRTPTION
A Refined Quality Assurance Tool for Today's Advanced Imaging Systems.
Proven simulation technology enables the use of tissue-equivalent, realistically-shaped phantoms for mammographic quality assurance.
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.
Contains targets that are engineered to test the threshold of the new generation of mammography machines. 4.5 cm thick and simulates an average glandular tissue composition.
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.
