Abstract: A low field MRI software and hardware acquisition system has been designed and characterized. The transmit-receive is not custom built. Instead, a low cost, commercially available Software Defined Radio (SDR) capable of transmission and reception of RF signals was used. An application for the SDR was built using the opensource program GNURadio. The custom built, relevant hardware was a Transmit-Receive switch, a RF probe, and a Halbach array of permanent magnets. The result is a system that can serve as a proof of concept for a low cost, portable, customizable MRI scanner. However, a NMR signal in the form of a Free Induction Decay (FID) remains yet to be detected.
