Abstract

A method is provided for detecting x-ray quanta incident on a multi-pixel x-ray detector having a two-dimensional matrix composed of measurement-signal-generating pixels, wherein the multi-pixel x-ray detector is embodied as a direct solid-state detector, wherein the pixels, which generate a measurement signal within a predefined time interval and which in addition lie in a contiguous cluster composed of a plurality of pixels, are assigned to an event cluster by an evaluation unit and wherein their measurement signals are drawn upon for the purpose of approximating the position at which the x-ray quantum interacted with the multi-pixel x-ray detector.
