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.

Abstract: 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.

Abstract: 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.

Abstract: In a method, apparatus, and computer program encoded with a data structure, for processing radiographic images and digital fluoroscopy radiographic (DFR) images acquired with the same imaging system using a single detector, three different types of image orientation are defined. These are a “system flip/rotation” that is dependent on the imaging system, a “pre-flip/rotation” orientation that is applied before the images are shown on a monitor, and a “post-flip/rotation” that is applied after an image is shown on the monitor. For this orientation change, the original image must be stored and subsequently manipulated. For pre-processing, DFR images are subjected only to the system flip/rotation, whereas radiographic images are subjected to the system flip/rotation as well as the pre-flip/rotation. For post-processing, both the DFR images and the radiographic images are subjected to the post-flip/rotation.

Abstract: A combination radiography and fluoroscopy system includes in one embodiment a radiography radiation generator and radiography radiation receiver, a fluoroscopy radiation generator and fluoroscopy radiation receiver, and a single computer system connected to receive signals from the radiography radiation receiver and fluoroscopy radiation receiver. The single computer system includes signal processing paths for the radiography signal and for the fluoroscopy signal wherein some processes or modules are common between the paths and some are path specific. The path specific processes are preferably connected in parallel. Common controls and a common interface are provided to the monitor connected to the computer system.

Abstract: Disclosed is a radiation image recording device comprising a source of radiation and a radiation receiver which are movable in a vertical direction in order to be positioned relative to a standing patient, and an image processing device for creating an output image based on the recorded image data. The source of radiation and the radiation receiver are movable in a controlled manner into successive image recording positions via a control device so as to record an area of analysis which exceeds the height of the active area of the digital radiation receiver, one radiation image being recorded in each image recording position. The positions are defined in such a way that the recorded radiation images cover the area of analysis while the image processing device is embodied so as to create a full image representing the entire area of analysis based on the image data of the individual radiation images.
