    Abstract: The present invention relates to an image reconstruction device and a corresponding method for reconstructing a 3D image of an object (7) from projection data of said object (7). In order to obtain 3D images having sharp high-contrast structures and almost no image blur, and in which streak artifacts (and noise in tissue-like regions) are strongly reduced, an image reconstruction device is proposed comprising: a first reconstruction unit (30) for reconstructing a first 3D image of said object (7) using the original projection data, an interpolation unit (31) for calculating interpolated projection data from said original projection data, —a second reconstruction unit (32) for reconstructing a second 3D image of said object (7) using at least the interpolated projection data, a segmentation unit (33) for segmentation of the first or second 3D image into high-contrast and low-contrast areas, a third reconstruction unit (34) for reconstructing a third 3D image from selected areas of said first and said second 3D image, wherein said segmented 3D image is used to select image values from said first 3D image for high-contrast areas and image values from said second 3D image for low-contrast areas.

    Abstract: A process for the preparation of fiber-reinforced plastic molding includes (1) shortening the fibers to a length of less than 30 mm; (2) introducing the fibers and the plastics present in the solid state, separately from one another, into a mixing chamber of a die press, wherein the plastic is in particulate form; (3) thoroughly mixing the plastic and fibers to give a solids mixture; (4) transporting the solids mixture through die orifices of the die press; (5) heating the solids mixture in the zone before or in the orifices of the die; (6) enclosing at least part or partly embedding the fibers by the plastic during or after the heating of the solids mixture; and (7) comminuting the granulated material for subsequent molding.
