    In ultra-low-field MRI (ULF MRI), spins precess in microtesla magnetic fields, and the signal is measured by superconducting quantum interference devices (SQUIDs). Low fields offer several advantages compared to conventional MRI such as narrow line-widths, enhanced T1 contrast, imaging of objects in the presence of metal, and a possibility for simultaneous magnetoencephalography (MEG) measurement. In this work, we describe the current state of our multichannel ULF-MRI system. We present phantom images and discuss technical solutions for coil design in a magnetically shielded environment.
