    Abstract: In a method and apparatus to generate a mammographic image, the apparatus has a radiation source, a digital radiation detector, and support plate and a compression plate between which the breast is compressed during image acquisition. A first image data set depicting the breast is acquired, with a first degree of compression of the breast. A second degree of compression of the breast is set and a second image data set depicting the breast is acquired. The first and second image data sets are linked for the generation of the diagnostic image.

    Abstract: A sequence of groups of projection images shows an object under examination comprising a vascular system and its environment. A computer determines a 2-dimensional evaluation image having a plurality of pixels based on combination images determined from the projection images of a group. The combination images have a plurality of pixels with pixel values. The sequence of the combination images shows the time characteristic of the distribution of a contrast medium in the object. The pixels of the evaluation image correspond to those of the projection images. The computer assigns each pixel, at least in a part area of the evaluation image, a type that is characteristic of whether the respective pixel corresponds to a vessel of the vascular system, a perfusion area or a background. It performs the assignment of the type on the basis of the time characteristic of the pixel values of the combination images.

    Abstract: A method and an x-ray computed tomography system are disclosed for visualizing at least two different types of cardiac tissue, such as normally perfused tissue, hypoperfused tissue and scarred tissue. In at least one embodiment, this is done by use of an imaging tomographic recording technique with the aid of x-ray radiation, wherein at least one cardiac region of a patient is scanned by x-ray radiation which passes through a first grating for the passing-through x-ray radiation, designed as an absorption grating, prior to reaching the patient, and at least the locally caused phase-shifts of the x-ray radiation in the cardiac region are also made detectable by using a second grating for the passing-through x-ray radiation, designed as a phase grating, downstream of the patient in the emission direction, and the spatial distribution of these shifts is measured and reconstructed, wherein an average specific phase-shift value is assigned to each spatial unit, wherein each of the abovementioned tissue types are assigned to a region of a typical specific phase-shift value and at least one region assigned to a tissue type is optically highlighted in a view of the cardiac region.
