Yes, but Is it in IMAX?


Researchers at the University of Leeds in the UK think a tumor might be easier to see if a doctor could image a patient's organs in three dimensions, says BBC News' Katia Moskvitch. So they created a method of generating high resolution 3D images of various tissues — the next-generation of digital microscopy, if you will — and recently published their study in the American Journal of Pathology. "A 3D image could help provide much more information than a simple 2D scan," Moskvitch says. "To create one, a piece of tissue must be cut with an ultra-precise machine called microtome into hundreds of very thin slices. Each slice is then put onto a 1mm-thick piece of glass and loaded into a digital scanner. The scanner then creates 2D impressions of each cross-section, and this is where the new technology comes into play." The software created by the Leeds researchers stacks the 2D images together to form a 3D shape. The team says this could help oncologists see small tumors, or even gauge a tumor's proximity to nearby blood vessels to see how easy it would be to remove.
