Patent ID: 8712138

Claim:
A device for generating soft tissue contrast images of an area of interest of an examination object comprising soft tissue, said device comprising: an x-ray source unit for emitting one or more pulsed pencil x-ray beams, an actuator for actuating said x-ray source unit along and/or around said area of interest to direct said one or more pencil beams onto said area of interest from various directions, an electromagnetic signal receiver for receiving electromagnetic signals from the area of interest resulting from absorption and scatter of x-ray photons within the area of interest, and a signal processor unit for processing said received electromagnetic signals and reconstructing a soft tissue contrast image of the area of interest, wherein said signal processor unit is adapted for reconstructing a soft tissue contrast image of the area of interest by use of a model using as model parameters one or more parameters, which characterize the interaction of photons with tissue within the area of interest to generate electric currents.
