AI Technical Summary
Conventional MRI systems face challenges in effectively cycling magnetic fields for enhanced image contrast due to practical limitations such as high energy deposition, difficulty in installing ferromagnetic inserts, and infeasibility of spin locking at high fields exceeding SAR standards.
A single-sided magnetic resonance imaging system is designed with a static field magnet and a solenoid coil for field cycling, allowing for low static external magnetic fields and pulsed radio frequency fields to alter the magnetic environment without exceeding SAR limits, facilitating spin locking and relaxation encoding.
This system enables improved tissue differentiation and image contrast by varying magnetic fields, reducing energy exposure and enabling relaxation dispersion measurements without major hardware changes, enhancing diagnostic capabilities.
