Interactive Volume Reconstruction and Measurement on the Grid

OBJECTIVES: To prove the advantages of integrating grid computing within medical image analysis software, and to discuss the technological, sociological and health care-related issues. METHODS: Presentation of an instant volume reconstruction and measurement tool (PTM3D) used in clinical practice, including percutaneous nephrolithotomy examples; description of a parallel implementation of volume reconstruction, evaluation of this implementation on lung and body reconstruction, presentation of the technical limitations for clinical use and description and discussion of a prototype grid implementation. RESULTS: Volume reconstruction can broaden its medical scope and use by accessing high-performance computing systems; interactive exploration of medical images can co-exist with the usual batch workload of grid systems; the EGEE grid middleware offers some of the required core services; a fully adequate computing environment needs further evolution to integrate realtime constraints. CONCLUSIONS: Clinical experiments of a grid-enabled PTM3D become possible...
