An 8 channel shoulder coil for high resolusion imaging
Hamamura Y, Brown B, Johnson K, Wheeler M, Hathaway J, Meurer K
An 8 channel shoulder coil with high surface SNR and deep tissue SNR is presented by optimizing the loop layout and introducing dual hinging mechanism to fit various patients body tightly. 1.5T and 3T coils were built and evaluated by both phantom and volunteer images. Phantom SNR showed 1.2 times higher than conventional four-channel coil at the labrum position and 2.0 times at the surface. Volunteer images showed SNR improvement at both medial and surface regions.
