  Magnetic resonance (MR) imaging relies on conventional electronics that is
increasingly challenged by the push for stronger magnetic fields and higher
channel count. These problems can be avoided by utilizing optical technologies.
As a replacement for the standard low-noise preamplifier, we have implemented a
new transduction principle that upconverts an MR signal to the optical domain
and imaged a phantom in a clinical 3 T scanner with signal-to-noise comparable
to classical induction detection.
