What happens when you take a high-technology, medical computed tomography (CT) system, remove 80 percent of the weight, shrink it to the size of a refrigerator, increase its imaging resolution, cut the cost by an order of magnitude, and optimize it to look at geologic core samples? What you end up with may look like the world's first cabinet-safe, portable, x-ray CT, wholecore scanner built by engineers and scientists at Lawrence Berkeley National Laboratory (Berkeley Lab).
