Does anyone have a tool for segmenting/masking the eyeball in MRI images? Specifically proton density or T2-weighted images.

The answer might look something like this brain MRI image on Wikipedia:
Except the image intensity might be flatter across the brain and eyes. In this particular image the eyes appear quite bright. I tried using the spherical Hough transform to detect sphere across multiple image slices, but it doesn't seem to be working reliably across multiple image datasets.
