GEMSS Project GEMSS: Grid-Enabled Medical Simulation
Services EC/IST FP5 Grid Project (1.9.2002-28.2.2005) Grid middleware initiative within medical
application setting. http://www.gemss.de/. GEMSS Consortium: 10 partners from industry
& academia including University clinics:NEC Europe Ltd, MPI Leipzig, ISS Vienna, CFX Ltd, CRID FUNDP, IT Innovation, USFD, IDAC Ireland Ltd., ASD, IBMTP Vienna.

GEMSS Objectives Demonstrate that the grid can improve pre-operative planning
& near- real-time surgical support by providing access to advanced simulation and image-processing services.
Build middleware on existing or developing grid technology standards to provide support for authorization, workflow, security and Quality of Service aspects.
Develop, evaluate and validate a test-bed for the GEMSS system, including its deployment in the end-user’s working environment.
Anticipate privacy, security and other legal concerns by examining and incorporating into its grid services the latest laws and EU regulations related to providing medical services over the Internet.

Maxillo-facial Surgery Simulation
Pre- and post surgeryCourtesy Dr. Dr. Th. Hierl, University Clinic Leipzig.
Modeling the distraction procedure
Provide a virtual try-out space for the pre-operative planning of maxillo-facial surgery.
Based on image processing, meshing & HPC Finite Element simulation.
Grid scenario: client-server, doctor uses a client machine to access remote HPC services.

An Example Scenario
GCC 2003 Shanghai China
Workflow Advantages Flexibility. The application can be
constructed at different levels easily and quickly using workflow mechanisms.
Reusability. A toolbox once developed can be reused in multiple applications.
Scalability. Workflow-based applications can be constructed in a hierarchical way, which provides possibilities for applications to scale up in a grid environment.
