What are normal relaxation times of tissues at 3 T?
The T 1 and T 2 relaxation times are the basic parameters behind magnetic resonance
imaging. The accurate knowledge of the T 1 and T 2 values of tissues allows to perform …

A low-cost and shielding-free ultra-low-field brain MRI scanner
Y Liu, ATL Leong, Y Zhao, L ** at high field
The large spatial inhomogeneity in transmit B1 field (B1+) observable in human MR images
at high static magnetic fields (B0) severely impairs image quality. To overcome this effect in …
