Abstract: A local connection of contact surfaces of top and bottom sheets is formed in a defined connection zone. The zone is polygonal and the top and bottom sheets jointly form within the periphery of this zone a connecting lip with their first side faces located opposite one another cut obliquely through their sheet thickness. These first side faces of the sheets and their adjacent obliquely-oriented second side faces in the zone are complementarily beveled in the form of a conical wall running downwards and inwards, so that in the vicinity of these second neighboring side faces the underside of the bottom sheet protrudes inwards past the top surface of the connecting lip at the location of the top outside edges of its first side faces. A method and an apparatus are arranged to implement the local connection.

Abstract: A fluoroscopy system for processing and real-time display of fluoroscopy images includes a buffer storing a first image when the buffer is below a threshold as a stored image; a unit processing the stored image and generating a processed image; a display displaying processed images; and a memory storing a second image as a stored unprocessed image when the buffer is not below the threshold, and storing processed images as stored processed images.
