qMRI乳腺成模体，美国QalibreMD qMRI定量核磁共振乳腺模体 - 专为MRI执行定量乳房成像而设计
qMRI乳腺成模体，美国QalibreMD qMRI定量核磁共振乳腺模体包括一套柔软的硅胶外壳，具有刚性聚碳酸酯内部结构。每个充满大量溶液以模拟纤维腺体组织T1。一种乳房标准是各种乳房组织的专用T1mimic，另一种是扩散模拟标准。乳房标准可以适用于大多数乳腺成像检测线圈。所有组件都可溯源到NIST，为MRI扫描仪和乳房线圈以及成像协议和程序提供准确的标准化。
对应的型号为：HPD BP131

Quantitative MRI (qMRI) Breast Standard-Specifically designed for MRI’s Performing 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 evaluates the following quantities:
B1 Non-uniformity
B0 Non-uniformity
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
