Funny that you mention CT scans. To quote from a paper[1] on the history of CT scanning: "Initial images were of inert objects, then specimens from an abattoir, including bullocks brains and pigs bodies" or "The prototype was installed at Atkinson Morley’s Hospital in South London where the first patient, a middle aged lady with a suspected frontal lobe tumour, was scanned on 1st October 1971. The surgeon who operated on her shortly afterwards reported that ‘‘it looks exactly like the picture’’" The default scientific approach to a new imaging algorithm, and especially a new implementation, it to try it on a simple well understood examples first.
