If you've ever been to a hospital, chances are you've walked by a room with a CT scanner. Maybe you've even been in one. Now to be clear, I'm not talking about an MRI machine (those use magnetic fields), but a CT scanner which uses an x-ray beam.

CT Scanners have been around since the the mid-70s but for the first decade, they produced only flat black and white images. Then on July 19, 1983 — 28 years ago — Michael W. Vannier, MD published the first 3D reconstruction of CT scan images. This became a game changer in CT scans, helping doctors prepare more accurately for surgery.

CT Scans are an every day occurrence now, but back in the early 80s, they were leading edge technology. We all know that technology is in a constant state of evolution: case in point, consider how much computers and their outputs have evolved in the past few decades.

Take a look at the image to the right. It's compiled using today's CT scanners, far evolved from the one Vannier and his team used. Now take a moment to check out the video below, and consider that in 1983 the computer used to view the graphics filled an entire room. And the screens were so small!

My how tech has improved...
