An X-ray imaging apparatus includes an X-ray generator including a plurality of X-ray sources, an X-ray detector configured to detect X-rays radiated from the plurality of X-ray sources and generate a plurality of pieces of projection data, and a processor configured to apply log projection to each of the plurality of pieces of projection data, to apply weighted projection to the log-projected projection data, to apply a bidirectional ramp filter to the weighted-projected projection data, and to generate a tomographic image reconstructed based on each of the projection data to which the bidirectional ramp filter is applied.

X-ray imaging apparatus and X-ray image processing method

An X-ray detector integral with an automatic exposure control (AEC) device can include an X-ray detection part configured to detect X-rays irradiated from an X-ray source and generate X-ray image data; and an automatic exposure detection board located below the X-ray detection part and configured to generate an X-ray sensing signal for automatic exposure control based on residual X-rays which have passed by or through the X-ray detection part.
