Professor Marsh huddles over a set of slides of his most recent subject. The slides are translucent save for the data that represent the subject. They are viewed by being fastened over a florescent light.

Second Technician Franks gently slides open the laboratory door. The sound of which is just loud enough for Professor Marsh to momentarily break concentration. The professor is also eager to inform his protégé of the scanning techniques that are used in the institute.

“Ah, Technician Franks, I’ve just pinned a Z-slide for us to peruse.”

Technician Franks is intrigued by the shapes on the slide which are sharply defined by the bright light behind them. The shapes are circular and repeat in ripple effect, broken on the outer edges.

He notices that there are two additional slides lying on the professor’s bench. They both have the same code as the slide pinned over the florescent light, except each has a differing suffix.

“Professor,” the Technician asks, “I see that these slides belong to the same subject yet they have an X and Y suffix, what is the difference?”

“Call me Spencer,” the professor kindly offers, “I think you know what XYZ means.”

“It’s a 3-D image,” Franks astutely states, “How does one combine the slides?”

The professor explains that each slide is scanned and saved onto the database. “Once the slides are processed we are able to build a unique profile of the subject. All manner of information may be extrapolated from this juncture.”
