1. An imaging device employing backscattered x-ray photons, comprising:
a plurality of x-ray sources configured to simultaneously emit x-rays and all configured to irradiate an analysis region in which an object to be imaged is placed,
a pixelated x-ray detector configured to simultaneously collect a plurality of distinct data, an image delivered by the imaging device being formed by juxtaposing the distinct data, the pixelated detector being placed so as to detect backscattered x-ray photons potentially scattered by the object from the plurality of x-ray sources,
an absorbing plate pierced with at least one orifice allowing backscattered x-ray photons potentially scattered by the object to pass through the orifice, the pixelated detector being placed so as to detect backscattered x-ray photons passing through the orifice.
