Design and realization of a multi-coil array for B₀ field control in a compact 1.5T head-only MRI scanner.

ABSTRACT:

Purpose

To design and implement a multi-coil (MC) array for B₀ field generation for image encoding and simultaneous advanced shimming in a novel 1.5T head-only MRI scanner.

Methods

A 31-channel MC array was designed following the unique constraints of this scanner design: The vertically oriented magnet is very short, stopping shortly above the shoulders of a sitting subject, and includes a window for the subject to see through. Key characteristics of the MC hardware, the B₀ field generation capabilities, and thermal behavior, were optimized in simulations prior to its construction. The unit was characterized via bench testing. B₀ field generation capabilities were validated on a human 4T MR scanner by analysis of experimental B₀ fi
