Parallel radiofrequency transmission (pTx) is a highly researched topic. As a result, researchers have implemented different in-house system designs to investigate its clinical benefits. The performance specifications of these custom systems are often unknown. Signal-to-noise (SNR) ratio analysis is an important consideration for optimal imaging. This work uses a simple multi-purpose method to conduct SNR analysis and noise characterization of a 4-channel pTx system integrated on an existing 3 T MRI system.
