Abstract:
1. A method for acquiring a series of x-ray images by an x-ray device comprising an x-ray tube and a flat x-ray detector in a medical procedure, comprising: successively moving the x-ray tube into a plurality of different angular positions; switching the flat x-ray detector to sensitive over a time window in each of the different angular positions; emitting an x-ray radiation to the flat x-ray detector by the x-ray tube within the time window; applying a backlight to the flat x-ray detector within the time window; acquiring an x-ray image in each of the different angular positions by the flat x-ray detector within the time window based on the x-ray radiation and the backlight; and setting a backlight intensity differently in each of the different angular positions.
