What is Very high Resolution Computer Tomography? April 21, 2008

Posted by tomography in HRCT.


In my latest post titled: “Dissecting Spiders with VHR-CT” I mentioned a technique called very high resolution computer tomography, and its use in the study of biological specimens. Now I offer you a large database called Digital Morphology that has several images that were taken using this technique at The University of Texas at Austin. But first, let us read the definition:

“High-resolution X-ray CT (Computed Tomography) is a completely nondestructive technique for visualizing features in the interior of opaque solid objects, and for obtaining digital information on their 3-D geometries and properties. It is useful for a wide range of materials, including rock, bone, ceramic, metal and soft tissue. High-resolution X-ray CT differs from conventional medical CAT-scanning in its ability to resolve details as small as a few tens of microns in size, even when imaging objects made of high density materials.”

It seems that these people are constantly throwing animals into their scanner so that they can render their 3D models and study them thoroughly afterwards. But they have come a long way. Digital Morphology visualizations have been featured by BBC’s HORIZON, NATIONAL GEOGRAPHIC EXPLORER, and in print by NATURE, SCIENCE, NATIONAL GEOGRAPHIC MAGAZINE, and THE NEW YORK TIMES!

Their scanner differs from your everyday medical-use CT scanner in that is has more penetrating power, and greater resolution. In fact, it was custom built for this sole purpose. I know I would not want to be scanned by this one!

Is the new CT750 HD scanner from GE likely to impede the ongoing slice war in the CT market?
