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 invention relates to a device (1) having a matrix array of electronic field elements (Fij), which may for example be sensor elements of an X-ray detector or pixels of a display. The field elements (Fij) are connected to access lines (Al, Dk) which, starting from a driver circuit (2, 3) at the border of the array, are routed in zigzag fashion along diagonals. In this way it is possible to provide address lines (Al) and data lines (Dk) which are locally orthogonal to one another and make it possible for individual field elements (Fij) to be addressed unambiguously. The associated driver circuits (2, 3) may be arranged at the same border or at opposite borders of the matrix, so that an array of almost any desired length can be put together from the device (1) without gaps in one dimension.
