ABSTRACT:
There is provided an apparatus and method for x-ray imaging of a subject that comprises an x ray source emitting a spectrum of radiation of low energy component as well as high energy component to be attenuated by the subject. At least one CR plate adapted to absorb mainly the radiation of low energy component that was attenuated by the subject is provided, wherein low energy x rays image can be attained on the CR plate as well as a DR plate that is adapted to absorb the high energy component, wherein the DR plate is placed further to the CR plate relative to the subject so as to attain image from higher energy x rays. The apparatus is further provided with a processor adapted to process the CR and DR images obtained in a single irradiation of the subject so as to obtain a third combined processed image.
