The STING imaging system based on using neutrons and gammas

We present a novel method for three-dimensional imaging of contrast agents in different specimens using neutrons. The contrast agent is an element with a high neutron capture cross section—e.g. B10. This element emits a γ -ray—478 keV in the case of B10—upon capturing a neutron. The γ -rays are then imaged with suitable tomographic imaging methods. We present a method of using a shadow mask technique for imaging which needs only one exposure and can yield depth information in addition to the two-dimensional projection.
