qMRI乳腺成模體，美國QalibreMD qMRI定量核磁共振乳腺模體 - 專為MRI執行定量乳房成像而設計
qMRI乳腺成模體，美國QalibreMD qMRI定量核磁共振乳腺模體包括一套柔軟的硅膠外殼，具有剛性聚碳酸酯內部結構。每個充滿大量溶液以模擬纖維腺體組織T1。一種乳房標準是各種乳房組織的專用T1mimic，另一種是擴散模擬標準。乳房標準可以適用于大多數乳腺成像檢測線圈。所有組件都可溯源到NIST，為MRI掃描儀和乳房線圈以及成像協議和程序提供準確的標準化。
對應的型號為：HPD BP131

Quantitative MRI (qMRI) Breast Standard-Specifically designed for MRI’s Perbing Quantitative Breast Imaging
The qMRI Breast Standard consists of an anthropomorphic set of pliable silicone shells with rigid polycarbonate internal structures. Each is filled with a bulk solution to mimic fibroglandular tissue T1. One breast standard is a dedicated T1mimic of the various breast tissues, and the other is a diffusion mimic standard. The Breast standard can fit into most detection coils for breast imaging. All components are traceable to NIST, providing for accurate standardization of MRI scanners and breast coils as well as imaging protocols and procedures.
Key Features
T1 Relaxation Mimic:
4 layers of alternating fibroglandular and fat mimics with T1 spread (100ms-1900ms)
12 spheres filled with fibroglandular T1 surrounded by bulk fat mimic
12 spheres filled with fat mimic surrounded by bulk fibroglandular mimic
Diffusion Mimic:
12 tubes filled with 0, 10, 25 or 40% aqueous PVP solution to mimic diffusion
4 tubes filled with fat mimic
Bulk solution is fibroglandular T1 mimic
The qMRI Breast Standard buates the following quantities:
B1 Non-unibity
B0 Non-unibity
Geometric linearity
Gradient Amplitude
System Center Frequency Drift (short time duration)
Resolution (High-contrast detectability)
SNR (Low-contrast detectability)
Accuracy and precision of T1 and T2 measurements
Accuracy and precision of the Apparent Diffusion Coefficient
