Development of a novel MR microscope using a clinical MRI magnet

提出了一种用于临床现场的低场(1-2T)磁共振显微镜的方法。该系统利用临床全身磁铁和便携式磁共振成像单元的磁场，独立于临床磁共振成像工作。使用1.5T临床全身磁铁的实验显示了清晰的2D图像(50μm^2像素)和3D图像(200μm^3体素大小)。因此，我们得出的结论是，所提出的系统可以是现有或未来临床MRI扫描仪的有用的附加MR显微镜，因为既不需要与扫描仪的电气连接，也不需要磁铁的成本。

An approach to the low field (1-2 T) MR microscope is proposed for use of MR microscopes in clinical sites. The proposed system uses the magnetic field of a clinical whole body magnet and a portable MRI unit, which works independently of the clinical MRI.Experiments using a 1.5 T clinical whole body magnet presented clear 2D images at (50 μm)^2 pixel size and a 3D image at (200 μm)^3 voxel size. It us thus concluded that the proposed system can be a useful add-on MR microscope to existing or future clinical MRI scanners, because neither an electrical connection to the scanners nor cost for the magnet is required.
