图书简介
This book covers topics in NMR/MRI at magnetic fields from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime, with an emphasis on imaging and understanding the human using its applications. Discussion of hardware considerations, relaxation contrast, imaging, artifact correction, and other applications unique to the ULF regime are presented.
