A method is for creating a synthetic mammogram based upon a dual energy tomosynthesis recording of an examination region. In an embodiment the method includes making a low energy tomosynthesis recording with a first X-ray energy spectrum; making a high energy tomosynthesis recording with a second X-ray energy spectrum of relatively higher energy compared with the first X-ray energy spectrum, wherein the examination region includes a contrast medium distribution; determining a subtraction volume based upon the high energy tomosynthesis recording and the low energy tomosynthesis recording; generating a three-dimensional probability map with a weighting factor per voxel based upon the subtraction volume; and creating a synthetic mammogram based upon the three-dimensional probability map.

The handling of the combined x-ray and ultrasound examination device is simplified by providing a compression unit with a compression surface which is permeable to x-rays and ultrasound and which is, or can be, coupled to a support element of the examination device irrespective of the existence of a mechanical and/or electrical connection between the ultrasound unit and the examination device.

Contrast-enhanced image data of breast tissue to be examined is generated. First two-dimensional contrast-agent-influenced x-ray projection data of the breast tissue are acquired at a first x-ray beam energy and a two-dimensional image data record is generated on the basis of the first two-dimensional x-ray projection data. Second two-dimensional contrast-agent-influenced x-ray projection data are acquired from different projection angles at a second x-ray beam energy that differs from the first x-ray beam energy and a three-dimensional tomosynthesis image data record of the breast tissue is reconstructed from the detected second two-dimensional x-ray projection data. Subsequently, a two-dimensional synthetic mammogram is calculated on the basis of the three-dimensional tomosynthesis image data record and a two-dimensional dual-energy mammogram is established by subtracting the image data of the synthetic mammogram from the image data of the two-dimensional image data record.

A method generates an image sequence using a tomosynthesis system. The image sequence represents an object under examination in rotating fashion. In a first step at least two projection data sets for the object under examination are captured. These have been acquired using different X-ray spectra in each case and from a plurality of acquisition angles in each case. In a further step at least one combination data set is calculated on the basis of the projection data sets. Subsequently in a further step the image sequence is calculated on the basis of the combination data set. An image sequence generating apparatus and a tomosynthesis system perform this described method.

A method is disclosed for graphically depicting a marker which is applied to an examination object in an imaging system. In an embodiment, the position of the marker is ascertained by way of a first measuring method. An image of the examination object is provided on the basis of a second measuring method, in which image the position of a graphical object that represents the marker in the image is ascertained and depicted on the basis of the first measuring method.

A method for simultaneous imaging of functional and morphological image data of a breast includes acquiring functional X-ray image data from the breast of a patient. In addition, morphological X-ray image data is acquired from the breast of the patient in the same breast position and with the same breast compression. A region of interest is defined on the basis of one of the two acquired data sets. A position of the region of interest is then determined in the other of the two acquired X-ray image data sets. The functional X-ray image data and the morphological X-ray image data are then each simultaneously graphically represented with the region of interest as a marked region. A diagnostic station, a non-transitory computer program product and a non-transitory computer-readable medium are also provided.

A method image scans a female breast in the context of projective digital mammography or tomosynthesis with prefiltered x-ray radiation. From a single scanning two spatially superimposing images are created on the basis of pixel-by-pixel or pixel-group-by-pixel-group different x-ray energy spectra. An x-ray mammography system contains a radiator-detector system having an x-ray tube with a filter for generating a prefiltered x-ray radiation having a first radiation spectrum and a radiation detector containing a multiplicity of partial areas which generate individual image pixels. The radiator-detector system is configured to the effect that the partial areas receive pixel-by-pixel or pixel-group-by-pixel-group different radiation spectra, such that the two images from different x-ray spectra are received with a single scanning of the female breast. Ideally, the detector is a pixilated x-ray detector with a converting sensor layer that is divided into at least two sets of partial areas, the sets having different thicknesses.

A method records a tomosynthesis data set of a breast of a patient with an X-ray device. The device contains an X-ray detector for the support of the breast, a compression plate for the breast and being parallel to the X-ray detector, and an X-ray source, which is movable in a basic angle interval around a central position, in which the midperpendicular of the detector area corresponds to the central ray of the X-ray source. The tomosynthesis data set is reconstructed from projection images recorded at different projection angles over a recording interval. A recording angle interval that is asymmetrical relative to the central position is used in the case of an asymmetrically positioned breast, in particular for an MLO view.

In a method and tomosynthesis apparatus for combined dual-energy mammography and tomosynthesis imaging of a predetermined volume of an examination subject, while contrast agent is flowing through the volume, an x-ray source is set to radiate x-rays at low and high radiation energy. A pre-shot of the volume is obtained with the high radiation energy, and recording parameters for high-energy images, low-energy images, and low-energy tomosynthesis scans are obtained from the pre-shot. A high-energy image is then obtained, followed by operating the x-ray source at a low energy, and a low-energy tomosynthesis scan of the volume is executed using the recording parameters, and a two-dimensional low-energy image of the volume is generated during the low-energy tomosynthesis scan.

In a method for producing 2-D recordings and 3-D recordings of a breast of a patient using an x-ray device that is operable in two recording modes and that has an x-ray radiation source and an x-ray radiation detector, the breast is placed between the x-ray radiation source and the x-ray radiation detector, and the 2-D recordings and the 3-D recordings are generated with the same breast placement. In order to keep the radiation exposure as low as possible in such a multi-mode x-ray device, all recordings are produced without the use of an anti-scatter grid, and a retroactive scattered radiation correction is implemented.

Multimode X-ray apparatus and method for the operation

A method for determining at least one three-dimensional image data record of a target area from two sets of projection images recorded with x-ray spectra using different energy maxima. A first set of projection images is recorded via a first X-ray spectrum and different first projection directions and a second set of projection images via a second X-ray spectrum and different second projection directions which differ at least partially from the first projection directions. A three-dimensional anatomy image data record is reconstructed from the first and the second projection images. A three-dimensional spectral image data record is reconstructed by a weighted combination of a first three-dimensional reconstruction image data record reconstructed from the first projection images, and a second three-dimensional reconstruction image data record reconstructed from the second projection images. The anatomy image data record and the spectral image data record are displayed.
