Process for the reconstruction of three-dimensional images of an area of interest of an object comprising the combination of measurements over the entire object with measurements of an area of interest of said object, and appropriate installation
Abstract
Process and installation making it possible to reconstitute precise images of an area of interest (2) of an object (1) by reducing the errors produced by the contribution of the compliment of the object. A first series of measurements is carried out, where a conical beam (10) only takes in the area of interest of the object (2) and this is followed by a second series of measurements in which the beam takes in the entire object. A combination of the measurements of the two series is carried out in order to make them compatible and obtain a more accurate image of the area of interest (2).
