Geometry Matters: High Performance Acceleration with Twisted Pair and Conventional Coil Designs at 7T MRI

Year: 2024

Type: conference-paper

Abstract: Motivation: Driven by the potential of the highly flexible twisted pair coil in creating unique sensitivity patterns for optimal acceleration. Goal(s): To compare geometry factors of the twisted pair and conventional copper coils, exploring effective arrangements for various coil shapes. Approach: Simulations of eight-element arrays containing circular and elongated coils; assessing geometry factors and the impact of random coil placements. Results: Findings emphasize similar geometry factors between the twisted pair and conventional coils. Moreover, random coil setups around a phantom do not inherently improve geometry factors. Impact: A comparison between twisted pair and conventional coils shows similar performance in g-factors. The flexibility of the twisted pair can be used to improve the g-factor but more work is required in finding the optimal shape of these coils.
