    Abstract: Soft body tissue, such as a female breast, is imaged using X-ray projection techniques and optical tomography techniques. First image data for a first image of a breast (17) are acquired by X-ray projection using an X-ray source (3) and an X-ray detector (5). Second image data for a second image are 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) improves patient comfort. Mammograms are 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 are used for image registration thereby possibly providing information for a deformation transform. Additional information on tissue composition within the breast is received by acquiring the first and second mammogram at different X-ray settings.

    Abstract: Described herein is an approach to identify a presence (or absence) of a tissue disease based on a quantification of a roughness of a surface of the tissue represented in imaging data. The approach includes an image data processor (120) with a surface roughness quantifier (206) that generates a metric that quantifies a roughness of a surface of a tissue of interest in 3D image data based on a surface model adapted to the tissue of interest in the 3D image data and a decision component (208) that generates a value signal indicating a presence or an absence of disease in the tissue of interest based on the metric.

    Abstract: The invention relates to a control module for controlling an x-ray system (140) during the acquisition of step images for phase imaging. The control module comprises a step image quantity providing unit (111) for providing a step image quantity, a detector dose providing unit (112) for providing a target detector dose, an applied detector dose determination unit (113) for determining an applied detector dose absorbed by a part of the detector (144) during the acquisition of a step image, and a step image acquisition control unit (114) for controlling the x-ray imaging system (140) during the acquisition of each step image based on the applied detector dose, the target detector dose and the step image quantity. The control module allows to control the x-ray imaging system such that the target detector dose is not exceeded while at the same time ensuring a sufficient quality of the step images.

    Abstract: The present invention relates to acquiring reference scan data for X-ray phase-contrast imaging and/or X-ray dark-field imaging. Therefore an X-ray detector (26) is arranged opposite an X-ray source (12) across an examination region (30) with a grating arrangement (18) arranged between the X-ray source (12) and the X-ray detector (26). During an imaging operation without an object in the examination region (30) the grating arrangement (18) is moved in a scanning motion to a number of different positions (a) relative to the X-ray detector (26) whilst the X-ray detector (26) remains stationary relative to the examination region (30) such that in the scanning motion a series of fringe patterns is detected by the X-ray detector (26). The scanning motion is repeated for a different series of fringe patterns. This allows acquiring reference scan data required for calibration of an X-ray imaging device (10′″) with less scanning motions.
