Experimental validation of simulated SNR loss due to noise coupling

Motivation: The aim of our study was to analyze the SNR loss due to noise coupling during reception with MRI coil arrays. Goal(s): In particular, we wanted to experimentally confirm the existing calculation methods. Approach: We compared the simulation predicted SNR loss due receiver noise against measurements for a single as well as for three coil elements. Results: A nice agreement was shown between theory and experiment. Impact: With our study, we also show how decisively noise coupling affects the SNR of an array.
