Abstract: There is provided an x-ray detector having a number of x-ray detector sub-modules. Each detector sub-module is an edge-on detector sub-module having an array of detector elements extending in at least two directions, wherein one of the directions has a component in the direction of incoming x-rays. The detector sub-modules are stacked one after the other and/or arranged side-by-side. For at least part of the detector sub-modules, the detector sub-modules are arranged for providing a gap between adjacent detector sub-modules, where at least part of the gap is not directed linearly towards the x-ray focal point of an x-ray source.

Abstract: Three-dimensional imaging of a breast tissue is achieved by acquiring a series of X-ray projection images from various angles. A three-dimensional image constructed from the projection images by a computer provides information to the operator to select a coordinate point within the breast from which to obtain a biopsy sample. Acquisition of projection images and construction of three-dimensional images is continued during the insertion of the needle into the breast, during positioning the needle towards the coordinate point, during the sampling and after the sampling. The advantages of utilizing tomosynthesis for breast tissue imaging over stereo imaging include better image quality, easier coordinate measurements within a tissue, ease of use of the equipment by the medical personnel, and fewer image artifact problems.

Abstract: A photon-counting detector includes a first subset of detector modules and at least one second subset of detector modules. Each detector module has power-consuming circuitry. Power-consuming circuitry of detector modules in the first subset is configured, in an operational mode in which the detector modules are powered on, to consume a first amount of power. Correspondingly, power-consuming circuitry of detector modules in the at least one second subset is configured, in the operational mode, to consume a second amount of power that is lower than the first amount of power.

Abstract: The present invention relates to a method and an X-ray apparatus comprising an X-ray source, an x-ray detector, and at least a first collimator having a first active position and a second collimator having a second active position for forming a bundle of X-ray beams, wherein both of said active positions are located in a substantially straight path between said X-ray source and said detector, but at different distances from said X-ray source. The X-ray apparatus further comprises a selector arrangement for switching one of said first or second collimators in said first or second active position, whereby when one of said first or second collimators is in an active position the other collimator is in an inactive position.

Abstract: A novel X-ray apparatus is provided for three-dimensional imaging and in particular for tomosynthesis examination, which includes an X-ray source having a focal spot, a collimator including a plurality of slits, a detector assembly including a plurality of line detectors corresponding to respective ones of the plurality of slits and an exposure volume arranged between the collimator and the detector assembly. The X-ray source, the collimator and the detector assembly are arranged in series, so that each line detector is aligned with the corresponding collimator slit and the focal spot, and is simultaneously displaceable by a scan motion relative to the exposure volume. The scan motion is primarily a rotation around a rotation axis arranged such that the detector assembly is situated essentially between the rotation axis and the X-ray source. Combined two and three-dimensional examination are also permitted according to the disclosed methods and apparatus.
