The large amount of information and computations is a critical problem in image processing. In this paper we show a highly parallel method to do image reconstruction which performs at real-time, using an asynchronous cellular array. The highly parallel architecture we propose is novel, its main cnaracteristic is the message communication mechanism based upon message routing and mailbox principles. After introducing the image reconstruction problem, we present the main reconstruction techniques and the sequential algorithms. We explain how to process these algorithms on a network. We describe this new integrated parallel architecture, its originalities and the system performing the whole reconstruction. We present the efficiency of this parallel image reconstruction method and the performance of the network.
