Simultaneous positron emission tomography/ magnetic resonance imaging(PET/MR) provides advantages in clinical and research applications of human’s brain. The two systems, MRI and PET, can work complementary to provide more information for medical diagnosis. As most research and clinical institutes already have MRI systems, an insert PET and matched MRI coil would be a more economical choice than a PET/MR system. In this study, we designed and built a dedicated quadrature birdcage/47Rx head coil array for PET insert on human’s brain study. The flip-angle maps and SNR performances were measured through a dedicated phantom. Anatomical images were scanned on a volunteer.
