发明名称 Method and device for reconstructing the shape and position of objects in space
摘要 The shape and position of objects in space can be reconstructed from at least two projections of these objects as obtained by transmission of waves influenced by their passage through said objects. The method includes determining for each point of the projections the distance traversed through an object by each ray derived from each of the sources, in determining the volume which contains the object and the rays which are derived from the at least two sources and pass through said object, in plotting the distances traversed by the rays within the object from external limits of the volume containing the object to define a first space which is located within the object, then in plotting the distances from the external limits of the first space to define a second space which is necessarily located outside the object but within the initial volume, and so forth.
