摘要

The invention concerns a method for three-dimensional imaging of a volume to be imaged executed by several computers connected in parallel: an emitting machine (13c) transmits to a network enabling transfer rates at least equal to 100 megabits per second (Mb/s), data delivered by an acquisition system corresponding to a set of projections of the volume, acquired in accordance with various incidences. The data are duplicated inside the network towards a plurality of processing machines (14a, , 14h), which receive each the received data. In each processing machine the correspondence between the received data and the transmitted data is ascertained. Each processing machine processes the data to reconstruct a fraction of the three-dimensional image of the volume to be imaged. At the end of the acquisition, and hence of the inline real-time reconstruction, a dedicated machine collects the set of fraction of images to reconstitute the three-dimensional image. The resulting improved systolic processing compared to the known multicast MPI (message passing interface) enables the speed, reliability and flexibility of the real-time tomographic restitution of moving small laboratory animals to be increased at a lower cost.
