An iPRES-W Coil Array for Simultaneous Imaging and Wireless Localized B₀ Shimming of the Cervical Spinal Cord.

ABSTRACT:

Purpose

To develop a wireless integrated parallel reception, excitation, and shimming (iPRES-W) coil array for simultaneous imaging and wireless localized B₀ shimming, and to demonstrate its ability to correct for distortions in DTI of the spinal cord in vivo.

Methods

A 4-channel coil array was modified to allow an RF current at the Larmor frequency and a direct current to flow on each coil element, enabling imaging and localized B₀ shimming, respectively. One coil element was further modified to allow additional RF currents within a wireless communication band to flow on it to wirelessly control the direct currents for shimming, which were supplied from a battery pack within the scanner bore. The RF signals for imaging were transferred via conventional
