The NextGen 7T scanner is equipped with a high-performance head gradient insert and hence the radial space available on the patient table for radiofrequency (RF) coils is limited. In addition to a large visual field to support fMRI studies, a split-top receive array on a sliding mechanism is desirable for improved patient comfort. We have developed a novel 8-channel transmit 64-channel receive 7T head coil and implemented a sliding mechanism to operate within the limited space in the head gradient insert. In this abstract, we present the overall coil design, transmit array performance and preliminary phantom results.
