The company has shown that with by using ultra-fast strong gradients, inexpensive low-field MRI systems can collect images that are comparable in quality (signal-to-noise ratio,resolution) to conventional (e.g., 3T) MRI. The company already has made large stridesin commercializing this advantage by conducting human studies (with a prototype) andby attracting investors.The prototype was built with 20th-century technology (e.g., electrolytic capacitors andcryogenic coils) which were bulky and do not lend themselves to mass production. In theproposed effort we will improve manufacturing capability by upgrading the electronicsand power storage sub-systems of our low-field MRI without compromising imagequality. These new subsystem designs are based on ultra-capacitor technology (originallydeveloped for hybrid cars) and electropermanent magnets (originally designed fordrones).The low-field systems will be used in neuro-operating rooms, neuro-ICUs, battlefields,athletic fields, etc. Inquiries for the product have come from serious distributors ofproducts in the fields of neurology, brain surgery, trauma, oncology, and otolaryngology,some of whom have already invested in the company. Documentation of this interest froma subset of interested partners and/or investors is included in the Letters of Supportsection of this proposal.
