In a method and apparatus for displaying an x-ray image acquired in a mammographic examination wherein the breast was compressed to a compression thickness, a breast area of the breast in an image area of the x-ray image is determined, and the glandular density of the breast area is determined from brightness levels of the x-ray image in the image area and from the compression thickness. A value that characterizes the glandular density is displayed together with the x-ray image.

A mammography device for examining a breast has a support plate and a compression plate, between which the breast is positioned and compressed during a radiographic examination. An ultrasound transducer for obtaining a sonogram of the breast is brought into direct contact with the breast either by temporary mounting in one of the support plate or the compression plate or by exchanging one of the compression plate or the support plate with another plate that contains the ultrasound transducer.

In a device and associated method to extract a tissue sample, spatial coordinates of tissue variations in slice images are determined and tested by a forward projection in projection images in order, with tested spatial coordinates, to create revised slice images with a precise localization of a tissue variation.

In a method and a mammography device, a virtual mask is created from an x-ray image of the breast for positioning the breast for a biopsy. The mask reproduces the image region covered by the breast tissue. A region targeted for the biopsy, and located within the breast tissue, is marked in the mask. The breast is then positioned for the biopsy in the mammography device between a support plate and a compression plate, the compression plate being provided with a recess for introducing the biopsy instrument therethrough. The mask and the compression plate are superimposed to cause the marked region to be located within this recess. The breast is then moved until the position and the contour thereof substantially coincide with the position and contour of the mask.

A swivel-arm with a gripper in a wire-processing machine transfers a processed wire to a collection tray. The collection tray and an unloading tray have a channel-like shape. The swivel-arm swivels the processed, trailing wire-end over the collection tray, whereby the wire, with the aid of the conveyor belt that runs in the direction of the arrow, falls into the collection tray. The collection tray serves as temporary store and collects a specified number of completed processed wires that corresponds to a production lot, and transfers the production lot to the unloading tray.

In a device for tissue extraction from a breast, a needle mount accommodating a biopsy needle can be placed by a connection element such that no regions of the breast that are to be examined by x-rays are occluded by parts of the device during an x-ray image acquisition.

A method and device for testing the tensile stress in tension elements of a tension element cord utilizes a measuring gage which is clamped between two tension elements of the tension element cord. The gage establishes a reference point relative to a fixed point stationary with respect to the tension element cord. The gage extends horizontally between two vertically extending length portions of the two tension elements. Then it is determined whether the reference point of the measuring gage is shifted with respect to the fixed point in the horizontal direction, wherein such a shift is dependent on a difference in the tension stresses in the two tension elements.

In an imaging system having a number of subsystems and a control device that controls the subsystems in a coordinated manner to implement a measurement sequence and an operating method therefor, sequence control data that define different functional sub-sequences of the measurement sequence are transmitted to the control device. Different active volumes are associated with the functional sub-sequences. In addition to the sequence control data, active volume position data are provided to the control device that define bearing and extent of the active volumes associated with the different functional sub-sequences. Control signals to implement the measurement sequence for the different subsystems are generated automatically by the control device based on the sequence control data and the active volume position data so that the individual functional sub-sequences are locally optimized at least with regard to a sub-region of their associated active volume.
