Claim One:
1. An apparatus for improved dynamic angiographic X ray imaging of a subject's body infused with contrast agent, said apparatus comprising: an x ray source capable of emitting an X ray beam directed to pass through the subject's body wherein said X ray beam is polychromatic; a sensor system capable of receiving an attenuated X ray beam that passed through the subject's body, wherein said sensor comprises: a detector divided into a plurality of detection elements, wherein each one of said plurality of detection elements is capable of converting photon energy of a portion of said attenuated X ray beam into electric charges; and at least one readout chip divided into a plurality of channels wherein each one of said plurality of channels is electronically connected to one of said plurality of detection elements and wherein each one of said plurality of channels is capable of converting said electric charges into digital data and wherein said at least one readout chip is provided with at least two programmable threshold discriminators; an acquisition system capable of receiving said digital data from said sensor and generate at least two electronic representations wherein one of said at least two electronic representations is attained from low energy photons and another one of said at least two electronic representations is attained from high energy photons wherein said at least two electronic representations are measured simultaneously at the subject and at a certain position of said X ray beam source; a processor capable of manipulating said at least two electronic representations into at least one image; and a display capable of displaying said at least one image, whereby said at least one image attained from at least two energy bins amplify the appearance of the contrast agent in blood vessels in respect with surrounding tissues of the subject's body.
