I'm surprised no one else has posted about this. Look what Bernie Madoff used in his offices: :D

Makes you wonder what everyone was doing with those 1600SWs--even with 3200x1024 desktops, they couldn't see that it was all a giant fraud?

There are some 1600SWs in NCIS.

Makes me wonder what are all these 1600SW connected to ?!

So this Octane wasn't in a film, it was scanning film. IMAX film.

Episode #3 of 'Science of the Movies'. http://science.discovery.com/tv/science-movies/science-movies.html

It's a very cool show, although the host is a douche.

Of course I'm the douche photographing his TV.

@GeneratriX: Yesterday I laid myself inside a 3 tesla-behemoth. (Fortunately only for studying reasons)

in this installation they use Dell Precision Workstations :-(
I created the image at home with the DICOM data on OsiriX - which is really a remarkable oss-software:

¡¡¡3 Tesla!!! ...almost enough to levitate a couple frogs! Geee...

Yeah, well... I guess Dell's are okay for that... but we have still to see something as much massive and heavy as an Octane chassis against E.M.R. ...or a Tezro, you know. I also know from a couple places using O2's for M.R.I.

Excellent, Geoman! ...I wonder myself if I could have something like that to create slices from all kind of things, ranging from speakers, to motors, transformers, etc... :) ...you know, I don't know a word about medicine (or maybe only the usual for an Average Joe), but I guess I'm always handy for the electronic stuff! ...the problem is... how could I capture slice-scans from inorganic solid stuff, without a gazillion bucks on big irons? :)

My first proper PC was a Dell Precision 650. I rather liked it. Most likely it's built-in U320 SCSI (LSI 2x320-R) made
all the difference, compared to a normal PC. The upper-spec Dells are pretty well built. as x86 systems go.


> ... I also know from a couple places using O2's for M.R.I.

I recently sold five O2s to a medical place in Argentina which uses them for this. Am also helping out a medical
place in Iran which uses O2s to control NMRI machines.


> Excellent, Geoman! ...I wonder myself if I could have something like that to create slices from all kind of things, ...

I have my brain in DICOM format somewhere (as it were), back from when I helped out with a project at Edinburgh
University. I did look into viewing it with whatever was available for IRIX, but it was messy sorting it out. Anything
easier one can use these days?

Other institutions still use Indigo2s to control scanners, though I've heard from the odd place which does use Octane
aswell.

Ian.

DICOM is still used in medical imaging, so there's still quite a respectable amount of software out there, some of it's even free.

A list is on http://www.sph.sc.edu/comd/rorden/dicom.html

Sadly little on IRIX. Supposedly you can use Image Magick to convert it.

@GeneratriX: There are even machines with 7 tesla tubes. The patient has to be inserted into it slowly not to become vertigo from the eddy current.

One can scan everything but magnetic metal. metals in general bring imaging problems, so for scanning non-organic matter like motors and transformators :roll: ;-) a roetgen tube or even a CT is the device of choice.

If you own a mac, try this OsiriX - it's very owerful but quite convinient to use.
I am currently looking for a DICOM viewer for IRIX (free/non commercial of course O:-) ), but seems like there are only commercial packages which have been sold by the MRI manufactured together with the machines.

@mapesdhs

You could try out http://www.slicer.org/ - there are versions for win32, solaris,linux and mac. And even the sourcecode.

So, was you then? :D ...those little cute crying babies are still kicking around, huhhh? ;)

Wow... that's an impressive amount of magnetic force! ...so, it is so big to produce induction of current along the organic cells and fluids? I've looked at most part of the weird videos from M.R.I. coils at YouTube, and looks like even with less than 3 Teslas, the effects over surrounding magnetic stuff are well strong!

I must be tired, that reference is way over my head. :D


> Wow... that's an impressive amount of magnetic force! ...

I think the record is 45 Tesla. Some research system in the US, reported in New Scientist. They levitated a frog.

I wanted to make a Tesla coil when I was young(er), back in the mid 1980s. I got as far as making a tube with
2200 hand-wound turns, 500V capacitor bank with 250J storage, mains operated clamp switch to fire the thing.
It could embed a nail in a wall from 20 feet away. 8) Probably about 0.000000000001 Tesla or something tiny... :}
But after that, I got into lasers instead. Ho hum.

Ian.
