AbstractLarge number of cables on RF array could produce serious electromagnetic interference, therefore, deteriorate the MR image quality. A 4-channel direct modulated optical fiber link has been designed and implemented to avoid these problems. The link performances are measured by bench tests. The optical link is used for a 4-channel neck coil array at 1.5T GE Signa MRI. The phantom and clinical images are successfully obtained by the optical link and compared to those by traditional coaxial cables. The SNR of the 4-channel phantom image using the optical link is 9% better than that using the original coaxial cables.
