After many years of research there is a new type of scanner now in use in two hospitals in texas. You all know about the traditional X-rays, the CAT scan (computerized axial tomography), the MRI (Magnetic Resonance Imagery) and the PETT scan (positron emission transaxial tomography). The new one, interestingly is cann a DOG scan (Digitalized Occillary Granular imaging) also called DOGI. It has nothing to do with a PETT as does the CAT but still interesting. It takes a deliberate grainy image (like a super blown up photograph or an old time type film camera picture) from an analog quick scan, then digitalizes it into a very grainy image. The grainy image converted from analog to digital actually shows up in B+W but highlights cellular aberrations in a distinctive gray. So I guess if you have a CAT you could also have a DOGI. This is true, really, I made it up myself.
