Virtual Nanoscopy Allows Scientists To Capture High Res Cell Map
hypnosec writes "Researchers have managed to generate ultra-large high resolution electron microscopic maps of cells by developing new tools that can combine thousands of images taken from an electron microscope thus enabling them to view a cell in its entirety. Use of electron microscopes reveals intricate structures of cells, but with a limitation that only a tiny portion of the cell is captured, which misses the bigger picture. If low-res images are captured to view a greater part of the biological structure, intricate details are missed. A team of scientists over at Leiden University Medical Center in the Netherlands has come up with a technique called 'virtual nanoscopy' that enabled them to ultrastructurally map regions of cells and tissue as large as 1 mm^2 at nanometer resolution."
... those Election Microscopes. :)
Awesome, I'd love to see what they can do eventually turning this into a 3d map. 1mm^3 at nanometer resolution would be a huge data set though. The possibilities of seeing the processes interact from different POV would be very cool though. Throw full motion into the mix and you've got yourself a nice base to create a near perfect replica of life.
It's basically just a variation the familiar technique of stitching together multiple photos to create a panoramic image. But it looks quite useful, because it allows the researcher to zoom in from a lower resolution view down to a high-resolution sub-cellular view. This is valuable, because with high-resolution electron microscopic images it can be "difficult to see the forest for the trees." An example is shown in the paper of visualizing a section of an entire zebrafish at e.m. resolution, a total of 281 gigapixels of data. Another example shows merging of lower resolution optical images of stained tissue with an e.m. resolution view.
Wow, they re-invented the Bacus Laboratories (now part of Olympus) WebSlide from 1994.
Looked, but didn't find any direct links to high resolution images. Anybody got them?
Is this much more than the tech behind stitching together multiple photos into a panoramic picture?
Well we've been assembling pictures this way for a hundred years, Google Maps being a recent example.
Nevertheless this may be the first time with an 'election' microscope so I'm sure it deserves a broad patent to protect the idea for the next hundred years (or whatever the term may become under the guidance of our elected officials).
...omphaloskepsis often...
have a 'montage' feature in their software, specifically for this purpose. This is common in nearly all SEM systems - additionally, most EDS (energy dispersive spectrometers) systems also allow simultaneous collection of elemental analysis to be added to the data 'cube' - so what actually is new here?
