Abstract: A method and device (1) for imaging soft body tissue such as a female breast is proposed. X-ray projection techniques and optical tomography techniques are combined. First image data for a first image of a breast (17) may be acquired by X-ray projection using an X-ray source (3) and an X-ray detector (5). Second image data for a second image may be acquired using optical tomography equipment comprising a light source (9) and a light detector (11). From the first image data, estimated bulk optical properties of the breast (17) are be derived. Based on such estimated bulk optical properties, an optical tomography image is reconstructed from the second image data with high image quality. Performing mammography acquisition at different compression states of the breast (17) may improve patient comfort. Mammograms may be acquired at two different compression states wherein a first compression state is adapted to provide high image resolution. At a second compression state, another mammogram may be acquired together with an optical tomography image. The two mammograms may be used for image registration thereby possibly providing information for a deformation prior. Additional information on tissue composition within the breast may be received by acquiring the first and second mammogram at different X-ray settings.

Abstract: An apparatus for and a method of correcting an image for an image artifact. An initial image is corrected by an image artifact corrector (190). The so corrected sample correction image is compared with the initial image to obtain information on the corrective action. The corrective action is then adaptively reapplied by a controller (140) to obtain an improved corrected image thereby ensuring previously present artifacts are removed and creation of new artifacts are avoided.

Abstract: A focusing grating device (100) is described comprising a substrate (402) and a grating comprising a plurality of grating features (408) positioned on the substrate (402). The grating features (408) are positioned non-perpendicular to the substrate surface, thereby inducing a first focusing direction. The substrate (402) is curved, thereby inducing a second focusing direction, which is different from the first focusing direction. An X-ray system (300) comprising such a focusing grating device (100) as well as a method for producing such a focusing grating device (100) are also described.

Abstract: In order to improve the mechanical stability of an X-ray grating with top bridges for X-ray dark field imaging and/or X-ray phase contrast imaging, it is proposed to reduce or prevent the undesired high stress on the top bridges by a change in the manufacturing process. Specifically, it is proposed to electroplate the top bridges after the bending. In other words, the electroplating of the top bridges is performed on the bent geometry.

Abstract: The present invention relates to a system (10) for X-ray dark-field, phase contrast and attenuation image acquisition. The system comprises an X-ray source (20), an interferometer arrangement (30), an X-ray detector (40), a control unit (50), and an output unit (60). An axis is defined extending from a centre of the X-ray source to a centre of the X-ray detector. An examination region is located between the X-ray source and the X-ray detector. The axis extends through the examination region, and the examination region is configured to enable location of an object to be examined. The interferometer arrangement is located between the X-ray source and the X-ray detector. The interferometer arrangement comprises a first grating (32) and a second grating (34). For a first mode of operation: The control unit is configured to control at least one lateral movement transducer (70) to move the first grating or move the second grating in a lateral position direction perpendicular to the axis. The control unit is configured to control the X-ray detector to acquire image data whilst the first grating and/or second grating is moving. During an exposure time of the X-ray detector the first grating and/or second grating has moved a distance less than a period of the first grating and/or second grating. The control unit is configured to control movement of the first grating and/or second grating such that the image data is acquired whilst the first grating and/or second grating is moving. For the first mode of operation the output unit is configured to output one or more of: dark-field image data, phase contrast image data, and attenuation image data.

Abstract: The present invention refers to providing a system that allows to very accurately determine the state of a disease, like COPD, in a patient. The system (100) comprises a unit (101) for providing images of the region of interest corresponding to different states of the region of interest, a unit (102) for elastically registering the images to each other resulting in an elastic registration output, a unit (103) for determining a specific tissue region in an image, a unit (104) for determining a specific elastic registration output for the specific tissue region based on the determined elastic registration output, and a unit (105) for determining an elastic indicator for the specific tissue type based on the specific elastic registration output. Thus, a state of a disease that influences the elastic properties of the specific tissue type can be determined very accurately.
