A 16-channel MR-PET array coil for high-resolution parallel transmit brain imaging at 7T
Motivation: We are developing the Human Dynamic NeuroChemical Connectome, a high spatio-temporal resolution brain PET (HSTR-BrainPET) scanner integrated with a 7T MR systemGoal(s): To build a 16-channel PET-compatible RF coil with parallel transmit capability based on an 8-channel test array for high-resolution imaging. Approach: We designed and built multi-channel transmit-receive coils with RF screen that fits inside the spherical geometry of the PET camera. Coil performance was characterized with and without PET modules present. Results: The performance of the 8-channel coil was satisfactory. Preliminary tests with the 16-channel array showed some loss in sensitivity in the CP mode. Impact: By designing a 16-channel transmit-receive RF head coil and RF screen that both conform to the novel spherical geometry PET camera, we can acquire high-quality MR data simultaneously with PET data while also minimizing 511 keV photon attenuation.
