Abstract: An apparatus for determining a functional index for stenosis assessment of a vessel is provided. The apparatus comprises an input interface (40) and a processing unit (50). The input interface is configured to obtain image data (30) representing a two-dimensional representation of a vessel (6). The processing unit (50) is configured to determine a course of the vessel (6) and a width (w1, w2) of the vessel along its course in the image data and is further configured to determine the functional index for stenosis assessment of the vessel based on the width of the vessel in the image data.

Abstract: The present invention relates to a device (10) for determining the position of stents (34, 36) in an image of vasculature structure, the device (10) comprising: an input unit (12); a processing unit (14); and an output unit (16); wherein the input unit (12) is configured to receive a sequence of images (24) of a vasculature structure (38) comprising at least one vessel branch (44, 46); wherein the processing unit (14) is configured to: detect positions of at least two markers (26, 28, 30, 32) for identifying a stent position (50, 52) in at least one of the images (24); detect at least one path indicator (64, 66, 74, 76) for the at least one vessel branch (44, 46) in at least one of the images (24) of the vasculature structure (38) at least for vessel regions in which the positions of the markers (26, 28, 30, 32) are detected; associate the at least two markers (26, 28, 30, 32) to the at least one path indicator (64, 66, 74, 76) based on the detected positions of the markers (26, 28, 30, 32) and the location of the at least one path indicator (64, 66, 74, 76); assign markers (26, 28, 30, 32) which are associated to the same path indicator (64, 66, 74, 76) to a marker group to indicate a position (50, 52) of at least one stent (34, 36) in the vasculature structure (38); and wherein the output unit (16) is configured to provide output data indicative of the positions of the markers (26, 28, 30, 32) of the marker group. The invention provides a device and a method that improve the determination of the position of stents in complicated situations.

Abstract: An adaptive X-ray anti-scatter device for placement in a source-detector axis of an X-ray imager includes an anti-scatter filter having a source orientable surface and a detector orientable surface. The anti-scatter filter comprises a plurality of realignable slats that absorb incident X-rays and are separated by a plurality of interstitial portions. The device also includes a first actively deformable member comprising a first set of one or more actively deformable actuators disposed across a first region of the first actively deformable member. At least a portion of the first set is partially or fully recessed within the interstitial portions. At least one actuator of the first set is in contact with a corresponding realignable slat of the plurality of realignable slats and is configured to change the alignment of the corresponding realignable slat in relation to the source-detector axis.

Abstract: The present invention relates to determining optimal C-arm angulation for heart valve positioning. In order to further improve the workflow in relation with the correct positioning of a valve prosthesis, it is described to provide (12) a 2D image of an aortic root of a heart of a patient, wherein the 2D image comprises three cusps of the heart in a visible and distinct manner. Further, 2D positions of the three cusps are indicated (14) in the 2D image. An analytical 3D model of the aortic cusp locations is provided (16), and the 3D positions of the three cusps are computed (18) based on the 2D positions and the analytical 3D model. Still further, an optimal C-arm angulation is computed (20) based on the computed 3D positions of the cusps, wherein, in the optimal C-arm angulation, the three cusps are aligned in a 2D image. The optimal C-arm angulation is then provided for further image acquisition steps.
