Abstract:
In this paper, ACR single image method and NEMA dual-image method were measured SNR using two types of phased-array coils. The correlation equation of the two methods was obtained and substitutability of two methods was analyzed. The results showed that the two methods are replaceable in the evaluation of coils, but the later method gets higher SNR than the first method because structure noise is eliminated.
