Gee Frank, you ask a lot of questions! 1) Who published the first paper on MRI? I'm not sure what MRI means. For example, who was the first to invent an airplane? What does that mean? Well, Leonardo did, maybe- but it didn't work. So maybe it was Otto Lilianthal- but those were motorless hang gliders, but he flew for many years- real flight. So maybe the French or the Write Brothers, those had motors but the tails in the front and didn't steer with ailerons. So maybe it was Chanute. I'm not even sure what an airplane is, let alone MRI. Let's say something using the same basic principles of modern imaging- easy! P.C. Lauterbur, Image Formation by Induced Local Interactions: Examples Employing NMR. Nature, 242, 190-191 1973 Well, what about Hinshaw, Bottley and Holland, Nature Vol. 270 22/29 1977? They show a human image using gradients to form sensitive points- definately a cousin of modern techniques. This harks back to Hinshaw, Phy. Lett, 48A, 87-88 (1974)- a very important work. And there were people doing localizations and measuring data in-vivo with NMR using gradient way before that... J Singer goes WAY back, somebody help with the dates? 2) Who had the patent? Patent on WHAT? Well, perhaps you mean the first thing that starts to look like a modern NMR imager... I would probably go with Edelstein, Hutchinson, Johnson and Redpath, 12 May 1980 where they announced and showed human results from their scanner, see patent applications 25899/78, 40779/78, 80/0773 2d Fourrier Transform reconstruction was pattented by Kumar, Welti and Ernst, sometime around 1975. Can't possibly have a modern MRI without that. Now, what the heck are you talking about the Supreme Court deciding? Do you even KNOW what Damadien's patent is called? It's called "Detection of Cancer by..." and the patent is that you can detect cancer based on a supposition that T1 and T2 differences between tumor from normal tissue were sufficient to detect cancer (which isn't true, it helps, but is not nearly conclusive.) Sorry, I didn't keep the Fonar patent around because... well, go get a copy, and you'll see why I wasn't very interested. It has nothing to do with making a picture. Frank, have you ever seen a FONAR? I mean the REAL Fonar, not the bogus one. Certainly not the NMR Imagers made by Fonar Corp. today- those are entirely based on techniques invented and patented elsewhere. It all revolved around creating a saddle shaped magnetic field to create a sensitive point. The patient was moved left to right and up and down, while data was collected from teh sensitive point. S/N was horrible, because it used a point measurement, not a 2DFT. Now, what does this matter? The Write Brothers invented the Airplane, but their company went broke. Not because "big business" stole their ideas, but because they couldn't make anything worth buying, and they were too pig-headed to adapt. The big questions are- 1) Did Fonar get money from their civil suit? How much? 2) What are they going to do with this to grow the company and increase revinues? 3) Will the market embrace their product? Stock prices will be driven by the future, not the past. Now, can you tell me how much money (net gain) I will see on the next 10Q from the law suit(s)? THAT is worth the bandwidth to talk about.
