Abstract: The present invention relates to an apparatus and to a method for mapping a three-dimensional space in medical applications for diagnostic, surgical or interventional medicine purposes. The apparatus and the method according to the invention use acquisition means, capable of recording two-dimensional images of said three-dimensional space from at least a first recording position and from a second recording position, and a reference target, comprising a plurality of marker elements and movable between a first target point and a second target point of said three-dimensional space. A processing unit, adapted to receive data indicative of a first image and of a second image of said three-dimensional space, comprises computerized means adapted to calculate registration data to register the two-dimensional reference systems, used to express the coordinates of the points of said first image and of said second image, with the three-dimensional reference system, defined by the marker elements of said reference target.

Abstract: A display having a modular element structure, including a tubular upright provided with a base and having at least one recess, pointed in at two longitudinally separate portions embracing the upright, each of the portions being provided with a projection complimentary to the recess, a threaded band of one portion meeting with a threaded band of the other portion when these are combined to form the collar, and then outwardly projecting lower band. The display also includes a tubular sleeve mountable over the collar from above and resting on all of the projecting band via a complimentary portion, the height of the sleeve being such as to leave the threaded band upwardly free, a plurality of beams fixed at least one end and an end piece which is provided with a device for hooking it to the tubular sleeve, and the ring nut which screws on to the threaded portion of the collar positions it so as to lock the end piece of the beam to the sleeve.
