7 Tesla 31P Birdcage / 16-channel 1H Loop and Dipole Array integrated with Parallel Transmit System

Motivation: Integrating multinuclear applications into parallel transmit system (PTx) at ultra-high field MRI systems will provide uniform transmit field and good SNR for both proton and the x-nuclei. Goal(s): Design, build and integrate a 7T 31P/1H head array into a 7T PTx system that supports multinuclear applications. Approach: Use 8 loops and 8 folded dipoles as 1H transceivers, and a birdcage as 31P transceiver, for 31P/1H MRS and MRI in a 7T PTx systemResults: Phantom and in vivo experimental results show that the coil can provide homogeneous and good SNR signals for both 31P and 1H in ROIImpact: Elevating multinuclear studies with 7T parallel transmit system, providing uniform transmit fields and good receive sensitivity profile for both proton and x-nuclei in ROI. A potential game-changer for metabolic studies in body applications at ultra-high fields, advancing medical research.
