Abstract:
A digital tomography system, comprising:an electron source that provides a pencil beam of electrons; an electromagnet assembly that receives said pencil beam of electrons and is configured and arranged to direct said beam of electrons along a selected path, to bend said pencil beam of electrons and to scan the bended electron beam along a line to form a scanning redirected beam; a linear target that is struck by said scanning redirected beam of electrons and generates a cone of x-rays that moves along a target line as a result of said scanning redirected beam; a slit collimator that receives said scanning cone of x-rays and generates a scanning fan beam, which are directed to an object under inspection, wherein each point in the object under inspection receives x-rays from various angles; a first line of detectors positioned in the same plane as the linear target to detect xrays that pass through the object under inspection, and provide sensed signals indicative thereof; and a processing system that receives said sensed signals and forms a digital tomographic image of selected planes through the object under inspection.
