摘要： An X-ray apparatus for image acquisition and a related method. The apparatus comprises a field-of-view corrector (CS) configured to receive a scout image (SI) acquired by the imager with a tentative collimator setting in a pre-shot imaging phase where said imager operates with a low dosage radiation cone causing the detector to register the scout image. The low dosage cone has, in the detector's image plane, a first cross section smaller than the total area of the detector surface. The field-of-view corrector (CS) uses said scout image to establish field-of-view correction information for a subsequent imaging phase where the imager is to operate with a high dosage radiation cone, the high dosage higher than the low dosage.

摘要： An X-ray detector comprises an array of pixels, each comprising a sensitive area, a body structure, and an electric circuitry. The sensitive areas are attached to, and arranged on, the body structure. The electric circuitry controls and reads out the sensitive areas and connects the sensitive areas with a processing unit. The sensitive areas provide an electric signal representing X-rays hitting the pixel. All pixels are provided in a pixel layout with a pixel layout scheme where the sensitive area is a first part of the pixel's surface that is contributing to the pixel's signal and a second part of the pixel's surface is irrelevant to contributing to the pixel's signal. To facilitate avoiding visual artifacts, the sensitive areas in a pattern in which at least a part of the pixels having the same pixel layout scheme such that the pixel layout of adjacent pixels is arranged differently.

摘要： The present invention relates to lung measurement. In order to provide enhanced information about a patient that facilitates further assessment steps, 2D X-ray image data of a patient's chest is provided, and the image data is segmented to identify lung structures to provide segmented image data separated from un-segmented areas. Further, spatial lung volume information is extracted from the image data using the segmented image data derived from the image data. Still further, lungs symmetry information is determined using the extracted spatial lung volume information. Finally, the lungs symmetry information is provided to a user. For example, a 2D X-ray image data of a patient's chest is provided (84) and a lungs mask image is formed (86) after the step of segmenting the input image data. Then, the lungs mask image is used to define areas, within which a predetermined adaptation is applied (88) to the original 2D X-ray image data producing a thorax mask image. Next, left and right images are provided (90) showing the left and the right spatial lungs volume information of the regions defined originally by the lungs mask image. Finally, based on the spatial lungs volume information, lungs symmetry information or total lung volumes may be calculated and provided (92).

摘要： The present invention relates to X-ray imaging technology as well as image post-processing. Particularly, the present invention relates to a method for computer aided detection of structures in X-ray images as well as an X-ray system. A computer aided detection algorithm visibly determines tissue structures in X-ray image information and subsequently matches the shape of a determined tissue structure with a library of known tissue structures for characterizing the type of determined tissue structure. The determination of a tissue structure and thus the characterization of the type of the tissue structure may be enhanced when employing also spectral information, in particular energy information of the acquired X-ray image. Accordingly, a method (70,80,90) for computer aided detection of structures and X-ray images is provided, comprising the steps of obtaining (72) spectral X-ray image information of an object, wherein the spectral X-ray image information constitutes at least one X-ray image, detecting (74) a tissue structure of interest in the X-ray image by employing a computer aided detection algorithm, wherein detecting a tissue structure of interest in the X-ray image comprises the computer aided detection algorithm being adapted to evaluate the X-ray image for tissue structure shape and compare the tissue structure shape with a plurality of pre-determined tissue structure shapes and wherein the computer aided detection algorithm is adapted to evaluate spectral information of the X-ray image for detecting the tissue structure of interest.
