A process for obtaining an x-ray image by means of a directly - converting, counted x-ray detector and directly - -converting, counted x-ray detector

摘要

The present invention describes a method (1) for obtaining an x-ray image (29) by means of a directly - converting, counted x-ray detector (10), the at least a grid (26) of the pixel electrodes (15) with defined location coordinates (25), an x-ray converter (13) for generating of charge carriers (20) in the case of incident x-ray quanta (12), a top - electrode (19) for generating an electric field (21) in the x-ray converter (13), and at least one detection means (16) to the spatially resolved detection of, over the time to the pixel electrodes (15) with defined location coordinates (25) incident, charge carriers (20), comprises. The method (1) comprises the following process steps:S1) during a certain period of time resolved detection and counting (24) of the pixel electrodes (15) incident charge carriers (20);S2) calculating an effective location coordinate (28) and an intensity (30) of a pixel, wherein in the calculation of the according to the specific time interval, localized counter reading (23) of the pixel electrodes (15) incident charge carriers (20) enters into.
