摘要： The invention relates to a medical tomosynthesis system (10) having an interventional device (15) and an image acquisition device (11, 12) for acquiring images of a subject volume in a plurality of angular positions around the subject volume. In the system, a three-dimensional geometrical model of the interventional unit is used to identify the projection angles of the image acquisition device that actually can be used. Preferably, this three-dimensional model is achieved by reconstructing it from projection images acquired with the X-ray image acquisition device. The invention also relates to a method for acquiring images with such a system.

摘要： In the generating of images by means of a two-dimensional field of image sensors, notably by means of a flat dynamic X-ray detector FDXD, adherence to the maximum data rate Gmax of an evaluation unit (1) requires satisfying the relation Δx·Δy·f/b≦Gmax between the width Δx and the height Δy of a sub-region of the image sensor read out, the imaging rate f and the binning factor b. In conformity with the method, parameters defining the size, position and/or shape of the sub-region can be preset at will, the other variables of the inequality being adapted, if necessary, in such a manner that the inequality remains satisfied. In the context of the method there is also performed a mosaic calibration during which calibration images of the complete image sensor are composed from calibration images of sub-regions.

摘要： The dynamic range of density or intensity values of pixels in an X-ray image is compressed in a manner preserving the range which is of primary interest for diagnosis, while still allowing recognition of detailed structure in the further ranges. This is accomplished by forming low-pass picture values (L) from input-picture values (E), determining equalizing values as a function (C) of the low-pass picture values (L) and forming output picture values by superposition of the input-picture values (E) and the equalizing values (C) . The equalizing values are chosen such that the output picture values are greater than the input-picture values (E) at relatively small low-pass picture values (L), below the range of primary interest, and the output picture values are less than the input-picture values at relatively large low-pass picture values (L), above the range of primary interest. Further, the output picture values substantially equal the input picture values for low-mass picture values (L) within the range of primary interest for diagnosis.
摘要翻译： X射线图像中的像素的密度或强度值的动态范围以保持主要感兴趣的诊断范围的方式进行压缩，同时仍允许在更远的范围内识别详细的结构。这是通过从输入图像值（E）形成低通图像值（L），确定作为低通图像值（L）的函数（C）的均衡值来实现的，并且通过叠加输入图像值（E）和均衡值（C）。选择均衡值使得输出图像值大于低于主要感兴趣的范围的相对小的低通图像值（L）的输入图像值（E），并且输出图像值小于相对较大的低通图像值（L）的输入图像值高于主要感兴趣的范围。此外，输出图像值基本上等于用于诊断的主要感兴趣的范围内的低质量图像值（L）的输入图像值。

摘要： In phase-contrast imaging, different types of image information, such as absorption image information and differential phase-contrast image information, may be obtained by a single image acquisition process and have different image properties. A frequency dependent combination of different types of image information is obtained, the combined image having improved properties over the image information and respective image information types. Accordingly, an apparatus and a method for image processing in X-ray imaging of an object is provided, including receiving first and second image information of the object of first and second image information types, respectively, where the second image information type is different from the first image information type. The first and second image information is combined to obtain combined image information of the object, where the combined image information is frequency-dependent, depending on spatial frequencies of the first and second image information, respectively.

摘要： An X-ray imaging system comprising a motorised X-ray tube located at a fixed focus position (12) relative to an object (14) to be imaged, and a motorised detector (18) for detecting the intensity distribution of radiation transmitted through the object. A control system (22) is provided for calculating two or more angles (Ot1) from which the object (14) should be exposed to radiation in order to cover the entire exposure field (H) occupied by the object (14) and for causing the X-ray tube to be rotated around the fixed focus position (12) so as to expose the object (14) to radiation from each of the respective angles (Ot1). The movement of the detector (18) is also performed automatically so as to correspond with the exposure angles so as to create two or more respective images of respective regions of the object (14) which can be subsequently stitched together to create a complete image thereof.
