After successfully demonstrating the first ultra-low field (ULF) magnetic resonance images of a human brain, our group has proceeded with the further development of this technology towards achieving whole-body imaging. A new custom-built apparatus was manufactured that is capable of imaging any part of the human body for a small adult subject. Using this setup, we obtained ULF magnetic resonance images of several soft tissues, including anterior knee images. In addition, we also calculated relaxation times at low field strengths. In this presentation, these results will be reviewed, along with future directions we plan to take this work.
