Affordable, state-of-the-art, magnetic resonance imaging scanners: Design and manufacturing insights

In the current study, design and manufacturing insights into the development of affordable, state-of-the-art, magnetic resonance imaging (MRI) scanners are provided, and imaging results to demonstrate their viability are presented. Perspectives on affordability and accessibility are given, followed by a set of scanner specifications that, if met, can satisfy these criteria. Next, the architecture of a concept scanner that can satisfy some of these requirements is outlined and explained in detail. Specific insights into the design modifications that can enable reductions in power consumption, weight, and form factors are provided. Scanner performance benchmarking via large American College of Radiology phantom imaging tests is reported. Human volunteer imaging results are shown for the most common clinical contrasts to establish viability and demonstrate body coverage. In summary, a ground-up approach for designing state-of-the-art, yet affordable, MRI scanners is described, along with insights into the future steps that must be taken to ensure genuine accessibility and affordability.
