Design of novel loop coil array for B0 and gradient field generation

Motivation: By adjusting individual coil currents, a loop coil array can generate a uniform B0 field and it offers the flexibility to control gradient field direction making it suitable for compact MRI systems. Goal(s): The goal is to show that the loop coil array produces a uniform and/or gradient magnetic fields. Approach: The current values of individual loops for a uniform magnetic field were determined by ptimization to achieve either uniform field strength, whose orientation can be rotated, or a linear field gradientResults: A method for calculating required current values has been presented, and simulations validate its effectiveness. Impact: Suggested coil arrays offer the potential for developing more compact and lighter MRI systems by substituting traditional magnets and 3-axis gradient coils in current low-field MRI setups.
