TECHNICAL DESCRIPTION

The installation has an emitting machine sending data related to a set of projections of a volume to be imaged, acquired in accordance with various incidences, to a network. The data are duplicated inside the network towards multiple processing machines that receive the data received relative to the emitted data. The correspondence between the received and transmitted data is ascertained in each machine. Each machine processes the data to reconstruct a fraction of a three-dimensional image of the volume to be imaged.
