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.
