    摘要： In a method for reconstructing 3D image data, a number of 2D central projections from different projection directions is acquired with a planar detector and radiation emanating from a radiation source, and a volume of interest of an examination subject to be three-dimensionally reconstructed is identified by mixing in variable and mutually dependent marks into at least two 2D central projections.

    摘要： In a tomosynthetic image reconstruction method and diagnostic device operating with such a method, a tomosynthetic 3D x-ray image is reconstructed by a discrete filtered back projection from a number of individual digital projection data recorded from different project angles within a restricted angular range, in which at least one filtering is performed with a convolution kernel that, in the local area outside of its central value, corresponds to an exponential function.

    摘要： In an image reconstruction method for 3-d image reconstruction, particularly a fast reconstruction method for rotational angiography employing a pyramidal X-ray beam and a surface detector, image reconstruction is accomplished in a computer using an algorithm of the filtered back-projection type, and, outside the zero component, the components of the convolution kernel correspond to an exponential function. A particularly fast image reconstruction is achieved with such a convolution kernel by using recursive filtering.
