One of the major challenges in very high-field magnetic resonance spectroscopy is the detection and characterization of the hippocampi deep inside the medial temporal lobes. The demands placed on the resistive shim systems by this application are beyond the capability of existing whole-body shim coil systems. We are investigating the development of an extremely high performance, high order, short, insertable shim set specifically designed for the medial temporal lobes of the human brain. A first goal is to determine how much improvement could possibly be achieved using such a shim set
