Active optical decoupling circuit for radio frequency endoluminal coil
Authors/Creators
Description
Nowadays, coaxial cables used to transmit MR signal to RF data cabinet are progressively replaced by optical fiber to
limit transmission loses [1]. Electro-optic conversion can also be done directly into the coil. It is also a mean to
overcome heating effects arising with metallic coaxial cables in the case of endoluminal coils [2]. A receiver coil should
also be decoupled during the emission of Radio Frequency (RF) pulses. In this work, an active optical decoupling
circuit for endoluminal coil is presented and compared to a reference coil with regular decoupling using bias signal
through coaxial cable.
