NMR signal reception is usually considered and benchmarked on the basis of SNR yield, acquisition speed or parallel imaging performance based on a specific trajectory and reconstruction paradigm. These benchmarks are therefore inherently bound to its reconstruction methods or acquisition schemes (trajectory, orientation, reduction factor etc.). In this work, a method is presented to measure the performance of a coil array or alternatively an entire acquisition sequence using an information theoretical approach. From this, a holistic metric of MRI signal acquisition could be derived.
