Abstract
It is an object to provide an imaging method and system. According to an embodiment, an imaging method comprises emitting neutrons into a material, wherein the material converts at least part of the emitted neutrons into a first plurality of gamma ray photons, and wherein at least part of the emitted neutrons pass through the material. Based on the neutrons passed through the material and the gamma ray photons, at least one property of the material can be deduced. An imaging method and an imaging system are provided.
