Abstract: In cardiac roadmapping, a “roadmap”, which is typically a representation of the vasculature of a patient obtained via previously acquired data from a CT scan, is overlaid on live intervention data, showing the position of an intervention device obtained using fluoroscopy. In this way, the intervention device may be tracked inside a realistic representation of the patient. The accurate registration of the fluoroscopic image to the roadmap data is an important step, otherwise the reported live position of the intervention device would not be shown at an accurate position inside the roadmap. Registration can be performed by the injection of contrast medium. In the case of cardiac roadmapping, the small vessel diameters mean that it is possible to register intervention devices directly. However, the behavior of intervention devices in larger vessels is difficult to predict, and so device-based registration is harder to achieve in such a context.

Abstract: In an airport baggage handling system bag information, flight information and airport topology information are provided to a central processor which determines a path for the bag through the handling system. The bag is scanned at various points along the path and the scan time is compared with a predetermined arrival time for the bag at the scan point. A bag is marked at risk if it arrives at a scan point after the predetermined time and the system may suggest an alternative handling path for the bag if it is determined that the risk of the bag not making an outbound flight is too high.

The processor is configured to perform a 3D-2D registration of a preoperative three-dimensional volume based on geometry parameters of an image data provider, which provides fluoroscopy images of an object of interest and a plurality of structures with interfering motions to be removed, for creating digitally reconstructed radiograph images of these structures for each fluoroscopy image. These are subtracted from the respective fluoroscopy images to generate structure-suppressed fluoroscopy images free from interfering motions. Based on these structure-suppressed fluoroscopy images, an angiographic image sequence is generated performing a motion estimation of the structures.
