X-RAY BACKSCATTER IMAGING OF AN OBJECT EMBEDDED IN A HIGHLY SCATTERING FLUID (Pending)
USA, PCT.
Teaches of an apparatus and associated method for obtaining a three-dimensional representation of a target object within a fluid-carrying conduit, such as a hydrocarbon exploration or production well, using high energy photons is provided. The representation is essentially a three-dimensional image that achieves visualization of the shape of the target object despite the intervening opaque fluids located between the imaging tool and the object. In one specific though non-limiting embodiment, a narrow, pencil-shaped beam of radiation is scanned in coordination with a similarly narrow detector field-of-view in order to sample the radiation-scattering properties of only a small volume of material at any given time. The result is a clearer to visualization with a greater viewing depth.
