Patent ID: 8761340

Claim:
A method for acquiring a high-speed dual-energy image pair using a pixilated digital detector comprising: selectively applying a voltage to each switch control line in the pixilated digital detector prior to a first x-ray image acquisition; acquiring a signal related to a first x-ray image; altering the voltage applied to a portion of the switch control lines in the pixilated digital detector prior to a second x-ray image acquisition; acquiring a signal related to a second x-ray image; and reading out the acquired signals simultaneously, wherein: the voltage is selectively applied such that the signal related to the first x-ray image is acquired in at least first and second non-adjacent pixels in the pixilated digital detector; and the voltage is altered prior to the second image acquisition such that the signal related to the second x-ray image is acquired in a plurality of adjacent pixels of the pixilated digital detector, the plurality of adjacent pixels including the first pixel and the second pixel.
