Neutron tomography
Encyclopedia
Neutron tomography is a form of computed tomography
involving the production of three-dimensional images by the detection of the absorbance of neutrons produced by a neutron source
.
It created a three-dimensional image of an object by combining multiple planar images with a known separation. It has a resolution of around 200–500 μm.
Whilst its resolution is lower than that of X-ray tomography, it can be useful for specimens containing low contrast between the matrix and object of interest; for instance, fossils with a high carbon content, such as plants or vertebrate remains.
Neutron tomography can have the unfortunate side-effect of leaving imaged samples radioactive if they contain appreciable levels of certain elements.
