Evaluation and simulation of eight-element phased-array surface coil in 3.0T MRI

Abstract

To evaluate the performance of a new eight-channel phased array surface coil, a standard sixteen volume coil was compared. Signal to noise ratio(SNR) and uniformity of the two coils was measured using two different sequences respectively. The images from a volunteer with the two coils were also evaluated.In addition, simulation analysis of the coil was done for further explanation of the coil performance. The results showed the SNR of eight-channel phased array coil was about three times of sixteen-channel volume coil but had a worse uniformity. The electromagnetic simulation experiment had a consistent result with the clinical imaging.
