英國利茲MagIQ MRI模體詳細介紹:
MagIQ MRI模體和MagIQ Duo MRI模體
MagIQ磁共振成像模型是磁共振成像(MRI)的圖像質(zhì)量模型,包括一個腔室(MagIQ)或兩個完全相同的腔室(MagIQ Duo),可以用不同的溶液填充以創(chuàng)建兩個測試對象(例如高場和低場)??梢允褂每偣?個(MagIQ)或10個(MagIQ Duo)單獨的信號隔室。
MagIQ配備3.5升 1.5T和3.0T磁共振成像解決方案。

MagIQ and MagIQ Duo
The MagIQ MRI phantom is an image quality phantom for Magnetic Resonance Imaging(MRI) comprising a single chamber (MagIQ) or two identical chambers (MagIQ Duo) which may be filled with different solutions to create two test objects (e.g. high field and low field). A total of 5 (MagIQ) or 10 (MagIQ Duo) separate signal compartments can be used.
MagIQ is supplied with 3.5 litres each of 1.5T and 3.0T MRI Solutions as standard.
Dimensions: 230mm dia. (254mm with caps) & 100mm deep (solo).
MagIQ includes the following features:
Reproducible positioning and test conditions
white pigment-filled centre markings
integral bubble level
external LCD temperature strip
Geometric Distortion
An array of 25.0mm uniformly pitched, high contrast circles
Spatial Resolution
LP/mm (1.0 LP/mm)
MTF edge block
Contrast Resolution
Fat Suppression
8 user defined compartments (4 x in each arrangement)
SNR / Ghosting / Uniformity
Flood-fill section for measurement of SNR, ghosting, uniformity
Slice Profile
Wedges or ′virtual plates′ can be used for slice profile measurements
Automatic Scoring Software (available separately)
