This study is designed to compare the channel numbers of multi channel T/Rx coils performace at 7.0 Tesla. 2,4,6 and 8 channel multi T/Rx coils are constructed with same dimension on 270mm diameter of acryl case. The 6 channel coil showed the best SNR in central and peripheral area compared to 4 and 8 channel coils. For parallel imaging techinique, we prefer to use the 8 channel coil which displays similar SNR with 6 channel coil, and the 6 channel coil may have benefit of some angiography studies which requires more contrast diference in central area. The 2 channel coil has no specific advantage in terms of both SNR and Tx power consumption.
