Some of their work involved X-rays produced by particle accelerators, devices that bring atomic particles into high energies.

X-rays are taken to see the break.

So we are looking at bio-markers, we're doing sophisticated X-rays, like functional MRI and spec-scanning to understand what happens in the brains of patients with fibromyalgia when they have pain, what happens to their brains when we treat that pain."
