Flexible multi-purpose integrated RF/shim coil array for MRI and localized B₀ shimming.

ABSTRACT:

Purpose

To develop a flexible, lightweight, and multi-purpose integrated parallel reception, excitation, and shimming (iPRES) coil array that can conform to the subject's anatomy and perform MR imaging and localized B₀ shimming in different anatomical regions with a high SNR, shimming performance, ease of positioning, and subject comfort.

Methods

A four-channel flexible iPRES coil array was constructed by enabling RF and direct currents to flow on the same flexible coil elements for imaging and shimming, respectively. Shimming experiments were performed with the coil array wrapped around the knee or neck of healthy subjects to demonstrate its high shimming performance and versatility. Additionally, its SNR and shimming performance in the knee were compared to thos
