Alternatively, the processing unit determines distances between at least three first distance sensors provided at the radiation generation unit and at least three second distance sensors provided at the detection unit based on signals emitted by the at least three first distance sensors to determine an orientation of the radiation generation unit and the detection unit relative to each other.

Abstract: A system and method for providing breast image data. A transmission request is transmitted from a workstation to an imaging server with identifying characteristics for a mammography image. A pre-determined breast window for the mammography image is identified. An unprocessed image stored on the server that corresponds to the mammography image is identified, and breast image data can be determined for unprocessed image. The breast image data includes a breast window image that can be determined by applying the pre-determined breast window to the unprocessed image. The breast image data is transmitted to the clinician workstation, and the breast window image is displayed at the clinician workstation.

Abstract: A motion correction method includes two steps. The first step includes a global motion correction using the bilinear warping technique and a rough delineation of the lung fields. One of the native images (low energy image, high energy image) is deformed to match the other image. In a second step, local motion corrections are applied to the globally motion corrected image by computing a proximity value in small overlapping tiles. Only tiles with a sufficient high proximity value are taken into account. The maximum shift applied in this second step is limited to a few pixels to avoid strong deformations of the native images.
