Designed by Researchers for Demanding Applications

MRI is a demanding context that combines extremely high sensitivity to noise and artifacts, with a harsh environment of both large magnetic fields and high energy radio signals. The radio signals alone are enough to destroy electronic circuits, and can even cause heating or fires in devices that are designed improperly.

The MREyes unit was designed from the ground up for high end applications, yet it is also optimized for extreme ease of use, reliability, and professional appearance.



The simple configuration of MREyes includes:

  • A specially-designed MR compatible video camera with purpose-built lens and enhanced infrared sensitivity; 
  • A compact power supply for the camera and illuminator, which combines conversion to noiseless optical signals;
  • An optical fiber connection that can be extended to nearly arbitrarily long lengths (up to 2km) to bring the video signal out of the MRI shielded room;
  • A converter box that reconstructs a standard video signal.

Performance and Noise

Because the signal used in magnetic resonance imaging is so small, even the tiniest extra radio signals can render MR images useless, yet the video camera itself contains hundreds of electronic components with the potential to radiate noise. With our experience, and our careful attention to engineering detail we have designed to the MREyes such that this noise is undetectable. The plots above show the results of the challenging Siemens Prisma noise tests. The noise floor on the left (without the MREyes unit) is indistinguishable from the plot on the right, acquired with MREyes in operation.
