Abstract:
1. A method of generating X-ray images for a medical procedure using at least one X-ray source, a first semiconductor detector arranged in a first plane and second semiconductor detector arranged in a second plane different from the first plane, the method comprising: generating a sequence of first X-ray pulses for recording a sequence of first X-ray images using the first semiconductor detector; generating a sequence of second X-ray pulses for recording a sequence of second X-ray images using the second semiconductor detector; omitting at least one of the first X-ray pulses so that the first semiconductor detector records a first dark image caused by scattered radiation; storing the first dark image; recording the sequence of first X-ray images; omitting at least one of the second X-ray pulses so that the second semiconductor detector records a second dark image caused by scattered radiation; storing the second dark image; recording the sequence of second X-ray images; correcting the sequence of first X-ray images based on the first dark image; correcting the sequence of second X-ray images based on the second dark image; and displaying the corrected sequence of first and second X-ray images and a first and second interim X-ray image while recording the first and the second dark images for performing the medical procedure.
