Computed tomography (CT) is a medical imaging method employing tomography. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The word "tomography" is derived from the Greek tomos (slice) and graphein (to write).
My journey started on Jan 4th 2010 when I went to the dentist for a check up, something I hadnt done for a few years. She asked me if I was a smoker which I answered No and I have never smoked in my life... with that she said that I should go to my GP. I asked why and she said "you have a black mark on the roof of you mouth" and showed me with a mirror. It looked horrible.
