MRI safe goniometer

[Dustin Grooms]

Anyone have any idea or experience with an MRI safe(no metal) goniometer? Digital or otherwise? Some sort of ability to output a signal for data capture would be nice or just any insights on anything used, even the traditional clinical handheld models made without metal pieces?

Thanks all!

Hi Dustin,

While not quite a goniometer, my group has used a fiber optic rotary encoder from Micronor in conjunction with a leg brace. It would be an expensive solution (over $3,000 for the encoder and interface module) but it is definitely MR-compatible and has great resolution. Let me know if you want more information.
