Concentric-loops coil reducing imaging noise and enhancing imaging SNR compared to traditional single-loop coil

Key Points

The concentric-loops coil achieves significant SNR gain, increasing it by approximately 1.7-2.6 folds compared to traditional coils.
Noise reduction reached between 15% and 30%, which significantly improves overall imaging quality.
Electromagnetic simulations and phantom tests were utilized to evaluate the coil's performance across various field strengths.
The novel design shows potential for optimization in various MRS and MRI applications, enhancing imaging capacity.

Abstract

Motivation: To improve MR imaging performance using advanced RF coil. Goal(s): To provide a new RF coil with largely improved signal-to-noise (SNR) compared to traditional single-loop surface coils. Approach: We designed a two concentric (primary and secondary) loops RF coil, and evaluated the coil performance via electromagnetic simulation and phantom tests. Results: The concentric-loops coil produces 1.4-1.6 times higher B1 close to the coil plane, and 15% to 30% noise reduction, resulting in approximately 1.7-2.6 folds SNR gain compared to the traditional single-loop coil across different nuclei and field strengths (17O at 10.5T, 31P at 7T and 1H at 1.5T). Impact: This simple novel coil can be optimized and adapted for a broad range of MRS and MRI imaging applications with largely reduced imaging noise, improved coil sensitivity and approximately doubled imaging SNR as compared to the traditional single-loop coil.
