Claim 0:
1. An X-ray imaging apparatus comprising:
a pulsed X-ray source having a control signal, wherein said pulsed X-ray source produces a fan or a cone shaped beam;
a time-sensitive X-ray detector having a time-dependent X-ray photon detection signal output and for one of:
providing for each photon detected at each pixel element a time of detection signal; and
being responsive to a gate signal controlling a time when photon detection is enabled or disabled;
wherein said time-sensitive X-ray detector comprises an X-ray sensitive scintillator and a light sensor array coupled with said scintillator for measuring X-ray detection events in said scintillator;
a processor, connected to said control signal and said time-dependent X-ray photon detection signal output, having an output for providing a measure of ballistic photons with a reduction in a measurement of scattered photons received by said time-sensitive detector;
wherein said time-sensitive X-ray detector is arranged with respect to said pulsed X-ray source so as to provide a different time of flight for said ballistic photons as a function of a pixel location within said time-sensitive X-ray detector; and
wherein said processor provides said measure of ballistic photons with said reduction in the measurement of scattered photons received by said time-sensitive detector using different timing as a function of location of said pixels.
