Abstract

A portable device for ultra-low field magnetic resonance imaging (ULF-MRI). This portable ULF-MRI device has applications for emergency care, surgery, battlefield care and other trauma applications. The portable ULF-MRI device includes multiple receiver channels, imaging coils and times, and provides enhanced contrast behavior of ultra low field imaging and pulse sequence optimization. Using the additional spatial information that derives from the use of multiple receiver coil, the invention discloses a novel means of MRI signal spatial encoding.
