Analog tomography
In the video in the link below GE literally slices many objects to give you a feel for what medical tomography can do non-invasively. It’s too bad they didn’t show the corresponding CT or MRI. I posted this back in October. With the Science on Google+: A Public Database explosion I thought I’d share it again.
I’ve seen it (awesome). LOL back at you Feisal Kamil
No comment from Rajini Rao and Gnotic Pasta ? I think Tom Lee might like the cut fruit.
I missed this, thanks for the tag Chad Haney ! Loved the sectioning through the fruits and veg. Why do they need to encase the object in resin first?
Dan is right. It’s analogous to the Visible Human project. In this case a resin was used because the were not worried about damaging the object. The human was frozen.
Chad Haney the tomography technique was first used in X-ray machines being taken over by to computerized tomography. MRI entered the imaging field and become very popular. Medical imaging technology has advanced by leaps and bounds in the last 15 years. The buzz word now is 3D. Everything the medical imaging developers are trying to get into the Radiologists head is 3D, from ultrasound, CAT scanner, MRI, to cardiac and neurology labs need to be 3D capable. The images produced by these scanner to display images of internal organs in slices are old news. I am not sure the 3D technique will be a major break through in early disease detection. I can tell that it does help in some cases and proven to be extremely useful, i.e neuro-interventional treatment of aneurism.
As to the demonstration by GE shown here, I do think the technique still has a long way to go, IMO.
Tom Lee I don’t follow you. Do you mean isotropic? MRI and CT are 3D and have been for years. The quick images are not isotropic as the out-of-plane resolution is very coarse. The point of the GE video was to show an analog analogy to modern medical imaging.
Agree that 3D has been around, but not up the the level everybody is seriously consider to use as real tools now. The GE video is kind of an advertisement of new techniques they try to develop for fighting cancer. From what I understand, GE is more into medical imaging technology. Since when did they get into this field? I have the feeling they are developing this technique to eventually incorporate with their medical systems. I still think they may have a long way to go. I do hope they can come up with a break through !
