A 4-Channel Head Coil RX Array has been created supporting Field-Cycling Imaging studies at an 8.5 MHz readout frequency. Head imaging to date, has been accomplished with a quadrature TX/RX birdcage coil.
The array goals include improved SNR, enhanced patient comfort, peripheral compatibility, with fast application to various sized heads.
Evaluation with healthy volunteers is now underway. The array appears well tolerated by individuals when compared to the 8-rung birdcage, accommodating a communication headset, and leaving the face quite open.
SNR is comparable to the birdcage at the image center and improved as you move towards the array elements.
