Microtomography, like tomography, uses x-rays to create cross-sections of a 3D-object that later can be used to recreate a virtual model without destroying the original model. THe term micro is used to indicate that the pixel sizes of the cross-sections are in the micrometer range. THese pixel sizes have also resulted in the terminology micro-computed tomography, micro-ct, micro-computer tomography, high resolution x-ray tomography, and similar terminologies. ALl of these names generally represent the same class of instruments. THis also means that the machine is much smaller in design compared to the human version and is used to model smaller objects. IN general, there are two types of scanner setups.
