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 qMRI乳腺成模體,美國QalibreMD qMRI定量核磁共振乳腺模體主要特征 T1放松模仿: 4層交替纖維腺體和脂肪模擬物與T1擴散(100ms-1900ms) 充滿纖維腺體T1的12個球體被大塊脂肪模擬物包圍 充滿脂肪模擬物的12個球體被大塊纖維狀腺體模擬物包圍 ![]() qMRI乳腺成模體,美國QalibreMD qMRI定量核磁共振乳腺模體擴散模擬: 12個管充滿0,10,25或40%PVP水溶液以模擬擴散 4管充滿脂肪模仿 散裝溶液是纖維腺體T1模擬物 ![]() qMRI乳腺成模體,美國QalibreMD qMRI定量核磁共振乳腺模體評估以下參數: B1不均勻 B0不一致 幾何線性 梯度幅度 系統中心頻率漂移(短時間持續時間) 分辨率(高對比度可檢測性) SNR(低對比度可檢測性) T1和T2測量的精度和精度 表觀擴散系數的精度和精度 ![]() ![]() ![]() 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 Accuracy and precision of the Apparent Diffusion Coefficient
