A quadrature birdcage/47Rx head
coil array designed and built for a dedicated PET insert was presented and
tested on a 3T MRI system. The coil performances have been verified through
flip-angle maps, SNR, and anatomical images.
Fig.5. 0.6
mm isotropic modulated flip angle technique in refocused imaging with extended
echo train (MATRIX) images were acquired using the quadrature birdcage/47Rx
head coil array at R = 7-fold acceleration. The acceleration direction was on
phase encoding and slice phase encoding. H = head; P = posterior; R = right; A
= anterior.
Fig.1. The (a.) application
scenario and (b.) coil wiring of the quadrature birdcage/47Rx head coil array. The
birdcage's size was displayed in red, the coverage of the surface coil was
displayed in blue, and the size of a single surface loop was displayed in yellow.
