I remember vividly the when CT scanners that were first put in The Johns Hopkins Hospital back in the 80’s. There were something like 5 scanners put in all at once. They were revolutionary and they blew our minds. The tests yielded grainy images and took an hour or more to construct via computer. Image evaluation was just beginning as well, so often-time the findings were of unclear significance or meaning.
Nowadays, our scanners take and process the images in the matter of a few minutes for the entire body, the scanners are ubiquitous, and the imaging accuracy & understanding has massively improved. I have seen this revolution during my career and it continues to benefits us through diagnostics and treatment in innumerable ways.
There are so many facets to CAT scanning that are fascinating, from the history of the CT scan as it relates to the music group THE BEATLES and their record company EMI (Read >>>>HERE<<<), to seeing how a modern scanner works behind the scenes view the video here.
