Design of Multichannel Two-row Quadrature Transceive Array for Ultrahigh field MR Imaging

Motivation: Increased sensitivity and sufficient image coverage is demanded for more efficient and comprehensive extremity imaging. Goal(s): Our goal is to exploit multiple-row quadrature RF coil array configuration to increase detection/transmission sensitivity and image coverage for human knee imaging at 7T. Approach: Due to the increase of the channel count in a multiple-row configuration, it is technically challenging to attain adequate decoupling between quadrature elements of the array. We address this issue by using a double cross magnetic wall decoupling. Results: The use of double cross magnetic wall decoupling have proven to be an efficient decoupling method. Impact: The feasibility of this work is a substantial achievement in the multichannel RF hardware engineering, poised to enhance MR imaging technology, especially in high-field applications, where multiple-row quadrature RF coil array configuration can significantly impact image quality and overall efficiency.
