A breast X-ray imaging apparatus comprising a detection mechanism and a needle holder. The detection mechanism may include a ray tube and a detector that is arranged opposite to the ray tube. An irradiated region may be arranged between the ray tube and the detector. The needle holder may be configured to move relative to the detection mechanism, and the needle holder may be arranged outside the irradiated region. A breast biopsy positioning device may be mounted on the breast X-ray imaging apparatus. The needle holder of the breast biopsy positioning device may be driven to move based on different workflows of the correction process and the verification process to move the needle tip of the puncture needle to a preset position, and a pair of stereo positioning images may be collected and identified. The accuracy correction and verification of the breast biopsy positioning device may be achieved by measuring the position of the needle tip and the preset position.

The present invention relates to mammography, e.g. tomosynthesis mammography. In order to provide a mammography X-ray imaging with improved data quality, a mammography X-ray imaging system (10) for tomosynthesis mammography is provided that comprises an X-ray source (12), an X-ray detector (14), a support structure (22), and a breast support (18) with a breast support surface (20). The X-ray source and the X-ray detector are mounted on an upwardly extending scan arm (24); the X-ray source is mounted on the scan arm above the breast support and the X-ray detector is mounted below the breast support. The scan arm is movably mounted to the support structure to perform a swivelling motion about a rotation axis (26) located below the breast support. During the swivelling motion, the scan arm swivels about the rotation axis such that the X-ray source and the X-ray detector perform a scan motion and an object on the breast support is radiated from different angular directions. A motion adapting mechanism (34) is provided that, during the scan motion, moves the X-ray detector along an adapted trajectory (36) that follows the breast support surface. In an example, the adapted trajectory is in alignment with the breast support surface.

Systems and methods for providing a real time visualization of scattered radiation in a medical facility are provided. A number of visualization devices such as augmented reality (“AR”) tracking devices, electronic displays, or projection devices are in electronic communication with a controller and configured to generate a visualization of scattered radiation. Position data is received from the position sensors associated with individuals in the medical facility, the AR tracking devices, radiation producing medical equipment, or radiation scattering medical equipment, and the visualization is adjusted accordingly.

A urological device include a patient table with longitudinal and broad sides, and an X-ray imaging system containing an X-ray source and an X-ray detector for detecting the X-ray radiation emitted by the X-ray source towards the patient on the patient table. A first linear drive is provided for moving the X-ray source parallel to the broad side and a second linear drive is provided for moving the X-ray detector parallel to the broad side, but in an opposite direction. A dedicated pivoting mechanism is configured to pivot the X-ray source around a first pivot axis.

A method and related apparatus (VS) for synthetic projection images, in particular synthetic 2D mammograms (S) formed from a 3D image volume T made up of slices (SL). It is proposed to compute a forward projection (FP) using a weighted average function that is implemented by a filter (FL). The filter function (FL) is configured such that that voxels in a slice with maximum sharpness are assigned highest weights thereby avoiding blurring by averaging with structurally less relevant slices.

A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.

Methods, systems, and related computer program products for processing and displaying computer-aided detection (CAD) information associated with medical breast x-ray images, such as breast x-ray tomosynthesis volumes, are described. An interactive graphical user interface for displaying a tomosynthesis data volume is described that includes a display of a two-dimensional composited image having slabbed sub-images spatially localized to marked CAD findings. Also described is a graphical navigation tool for optimized CAD-assisted viewing of the data volume, comprising a plurality of CAD indicator icons running near and along a slice ruler, each CAD indicator icon spanning a contiguous segment of the slice ruler and corresponding in depthwise position and extent to a subset of image slices spanned by the associated CAD finding, each CAD indicator icon including at least one single-slice highlighting mark indicating a respective image slice containing viewable image information corresponding to the associated CAD finding.

The present invention relates to a smart apparatus for acquiring patient images, the smart apparatus being structured so as to integrate capabilities for acquiring two-dimensional images and three-dimensional images into a single piece of equipment, thereby allowing the expense and installation space therefor to be minimized.
