The receive coil geometry significantly influences MPI detection sensitivity, a primary distinguishing characteristic when competing with other tracer-based imaging methods. Here, we compare four gradiometric receive inserts for non-human primate functional MPI to identify a coil geometry that maximizes sensitivity while accommodating the primate head. A cylindrical coil with a diameter of 14 cm provided the highest sensitivity while fitting the macaque. Smaller cross-section gradiometers offered better rejection of noise originating from the shift coil amplifiers.
