This study shows the feasibility of
optical conversion of the RMN signal at 7T as a potential solution for the replacement
of coaxial cables. Further study of noise sources is required to preserve the
inherent benefits of this technique.
Signal conversion setup. The signal is
transmitted by coaxial cable in path A, and by coaxial cable with an EO
conversion and an OE conversion in path B. The amplitude of each signal is monitored
by a spectrum analyzer.
Images acquired using regular galvanic connexion
(left) and OE conversions with fiber optic transmission. The SNR are
respectively 162 and 5 (ratio of 32). Inner diameter of tube is 15mm.
