A method is for making an X-ray recording of an examination region of an examination object with an X-ray system including an X-ray source arranged on an emitter displacement unit and an X-ray detector including a detection area, arranged on a detector displacement unit. The method includes selecting the examination region and portion-wise recording successive recording portions in relation to the examination region. The portion-wise recording includes moving the X-ray source and the X-ray detector, determining a strip-shaped detection region within the detection area, by expanding an extent of the X-ray recording compared with a further different X-ray recording, and acquiring and recording each respective successive recording portion, of the successive recording portions, using the determined detection region and the X-ray source. Finally, the method includes generating an assembled X-ray recording of the examination region from the successive recording portions recorded.

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.

Method and device for detecting x-ray quanta

An X-ray detector of conventional design having photodiodes and scintillator material arranged thereon is able, given a suitable read-out frequency matching a low dose to which the flat-panel X-ray detector is subjected, to obtain images during each read-out operation, from which images the energy of individual X-ray quanta can be derived. An item of X-ray-spectrum information about pixels in a grid pattern can be obtained thereby.

A sensor element is provided for conversion of x-radiation into an electrical measurement signal, the sensor element including an x-radiation-absorbing fluid arranged in a housing, and a pressure sensor arranged to detect a pressure of the fluid on the pressure sensor and convert the detected pressure into an electrical measurement signal. A plurality of such sensor elements may be arranged in a matrix-type arrangement to form an x-ray detector.
