Development of a Compact Head-only Scanner with a Window and Shoulders Outside its Vertical Bore.
Motivation: MRI has evolved into an indispensable tool, but remains inaccessible to much of the world’s population. Goal(s): To build a compact, low-cost, mid- to high-field MRI system capable of producing diagnostic-quality images. Approach: A complete redesign of MR scanner architecture and key technologies; including a compact high temperature superconducting magnet, multi-coil gradient array, and digital spectrometer. The system required extensive testing prior to integration and initial imaging. Results: Initial experiments produced high-resolution images despite using an extremely inhomogeneous magnetic field from the compact 0.7 tesla magnet. Impact: This work represents a significant milestone within the MRI community to address the problems in accessibility and under-utilization facing MRI today. By focusing on ways to develop portable, low-cost systems, the accessibility of this imaging modality can increase substantially.
