[[Narrator] This is our new premium CT scanner, hi-def.]

[Global research was asked to revolutionize the way we take imagery.]

[[Jim Vortuli] In a history of computer tomography, there have only been]

[2 simulated materials ever been used, and we were asked to invent the third.]

[A scintillator is a ceramic that converts x-rays into light.]

[Most everyone is familiar with the garnet gemstone that you might have on your ring.]

[What we have here is a fully man-made garnet.]

[In the world of luminescent science -- luminescent being things that convert]

[x-rays into light -- the garnet crystal structure is very efficient at doing that.]

[What we did which is new and novel, is change the chemistry ]

[of these well-known garnets and make them even more sensitive.]

[They produce more light for a given x-ray.]

[What you're seeing here glowing is the gemstone simulator.]

[It's being illuminated by a UV flashlight.]

[This is exactly what it is designed to do in a CT scanner.]

[It's designed to take x-rays that are being cast on the simulator, is then converted into light.]

[[Bob Senzig] The gemstone detector pushes the technology]

[with respect to resolution, pushes new capabilities in spectral imagining ]

[that have never been seen before in CT.]

[There are certain materials in the body that have the same density]

[but have a different composition.]

[This system will be able to differentiate those materials.]

[It was a bunch of scientists that understood about what makes things sinnilate ]

[with the periodic table, and we started out with hundreds of different compounds.]

[[Carl Vess] This is the gemstone pilot facility.]

[What we're doing here is actually making prototype batches for GE health care.]

[This is the building block of what gemstone is, so what we end up doing]

[is taking individual powders of each one of these different atoms.]

[This powder is the first time that the garnet has been formulated,]

[and that powder is compacted and pressed and forms these wafers here.]

[We then heat this up, and that oven converts them into this yellow material]

[that you see here.]

[It's done with a much larger piece of this, almost like a brick size]

[at their manufacturing center, is we dice it up into small pixels.]

[Here is a gemstone detector.]

[This is comprises the portion of the whole CT scanner.]

[The response has been fabulous.]

[They've just seen features that they've never seen before.]

[Essentially, freezing the motion of the heart, they can look into the blood vessels ]

[that line heart and tell that they're fully closed,]

[or what's even amazing to me, even partially closed.]

[It's really delivering what the doctors want, which they want better image clarity.]

[They want to see more. They want to know more.]

[It's just great to be a part of that.]
