3 3 Phase 1 Consideration & specification of tasks 1) review of recent proceedings in the field of the project : study present medical image processing and reconstruction algorythms, select the best for parallelisation, collect the most up-to-date methods in the field of parallel data acquisition, review of standard GRID implementations (eg. Globus), pick the one most suitable for the project, contact other GRID projects. 2) hardware specification, cluster implementation

4 4 Phase 2 Cluster building, planning UPS switch 100 MBit /1GBit IDE-RAID 200-600 GByte fileserver node node 4 – front-end machine UPS switch RAID file server node 0 node 1 node 2 node N node N-1 LAN DAQ

5 5 Phase 3 Implementation I. creation of a C++ based volumetric software library in parallel environment USB, firewire,DIO or Gigabit Ethernet based high speed data acquisition nodes in the cluster cluster integration (logical, physical)

6 6 metacluster Phase 3 Integration of clusters Cluster A Cluster B GRID-integration Internet

7 7 Phase 4 Implementation II. optimisation of the parallel volumetric software library using the developed test programs testing data acquisition nodes, implementing parallel event processing algorithms cluster integration, GRID implementation

8 8 Phase 5 GRID integration & optimisation running visualization and other image processing algorithms in cluster and meta-cluster environments, optimising visualization, optimising data acquisition programs GRID integration, forming a Virtual Organization, the system can appear in the Hungarian GRID

9 9 Phase 6 complex integration, quality monitoring running the programs in environments with different resources (dedicated cluster, cluster with dynamically changing number of nodes, meta-cluster, GRID) Using clusters in commercial medical image processing facilities?
