Abstract

We describe the design and performance of a 28-channel RF receive array optimized for human head ¹³C imaging at 3T. The array employs a fixed and symmetric cylindrical geometry to provide predictable prior information of the coil sensitivity profiles, which can be used to resolve practical challenges of hyperpolarized parallel imaging and to improve performance. The results show good SNR and spatial encoding of the different elements, with only small performance difference between the individual elements.
