Twstr: A Resonant, Matched MRI Coil without any Discrete Components

Motivation: Component-less MRI coils have the potential to increase the strength and flexibility of array elements making them suitable for implantables, multi-modal imaging, and body conformal applications. Goal(s): As a result, this work strives to demonstrate a resonant, matched MRI coil without the use of discrete components. Approach: A Twstr coil is composed of a single Twisted-Pair wire manipulated by twisting and cutting such that the coil presents a match at its resonant frequency. Results: Twstr coils have a high quality factor, similar SNR performance in a Rx-Only configuration, and outstanding TRx capabilities when compared to a standard loop coil. Impact: Twstr coils are component-less, flexible MRI coils made from a single piece of Twisted-Pair wire. Such coils eliminate the need for discrete components on a coil providing a viable solution for implantable and multi-modal imaging coils without compromising performance.
