The squirrel monkey has similar functional and microstructural organization of the central nervous system of humans. Therefore it holds the potential to provide guidance for further explorations into the brain structure and function especially if investigated at ultrahigh magnetic field strengths. However, the dimensions of the preclinical MR systems, the size of the squirrel monkeys head and the necessary animal handling present considerable constraints for the RF coil desing. Accepting this challenge, this work presents a design and first results of a dedicated RF coil with a large inner diameter and a thin wall for MR imaging at 11.7 T.
