Abstract

A whole body RF coil array module configured for cryogenic cooling for use in magnetic resonance imaging. The RF coil array may be a superconducting coil array, such as a high temperature superconducting (HTS) array. The RF coil array module provides sufficiently high signal-to-noise ratio and large field of view such that the RF coil array may be used in an MRI whole body system for diagnostic imaging of all body parts without requiring using special-purpose RF coils for different body parts.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 61 / 484620, filed May 10, 2011, which is hereby incorporated by reference in its entirety for purposes of each PCT member state and region, wherein such Incorporation is permitted or otherwise not prohibited. technical field [0003] The present invention relates generally to magnetic resonance imaging and spectroscopy, and more particularly to magnetic resonance imaging and spectroscopy devices employing superconducting components, and methods for making such devices. Background technique [0004] Magnetic resonance imaging (MRI) technology is commonly used today in larger medical institutions worldwide and yields significant and unique advantages in the practice of medicine. Although magnetic resonance imaging has been developed as a well-established diagnostic tool for imaging structure and anatomy, it has also been developed for imaging functional activity and other b...
