Cardiac imaging on mice needs both high performance
gradient systems and optimized RF coils. The limited
available space leads to either optimized gradient
performance with a birdcage as Tx/Rx coil, which is the
most commonly used design. Alternatively, larger
gradient diameters allow for operating (large) Tx
resonators and receive arrays. The aim of this work is
to develop a Tx resonator and an Rx coil array,
optimized for murine cardiac MRI and to be combined with
a high-performance microscopy gradient system. Bench and
MRI characterizations are provided, and a comparison
with a quadrature driven Tx / Rx coil is performed,
demonstrating superior performance of the coil-array for
cardiac imaging.
