SEE-Grid-Project

The SEE-GRID project was a work package of the Austrian Grid project; its name within the project was WP A-1c (Virtual Eye Surgery). The work package leader was the Research Institute for Symbolic Computation (RISC) at the Johannes Kepler University Linz. The work was accomplished by RISC and RISC Software GmbH in close cooperation. The main goal SEE-GRID was the automation of pathology fitting. The SEE-GRID project was successfully finished by the end of 2009.

In SEE-GRID, we extended SEE++ in two ways:

  • Parallel computation of simulation predictions in the grid
    SEE++ uses non-linear optimization algorithms to simulate eye muscle forces and eye positions. In SEE-GRID, this simulation was performed in the grid using parallel versions of the optimization algorithms; these were executed by a server component running remotely on a massively parallel supercomputer.

  • Distributed calculation of simulation parameters in the grid
    In clinical analysis, fitting algorithms have to be applied to construct the parameters of the simulation from measured patient data. In SEE-GRID, this pathology fitting process was distributed among remote grid nodes. The derived simulation parameters were provided to a prototype implementation of a SEE-GRID database in order to archive patient treatments and search through previous surgical treatments for the best matching surgical procedure.

In SEE++, the high computational demand for the simulation and for the calculation of simulation parameters makes clinical analysis of pathologic eye movements difficult. The goal of SEE-GRID was near real-time performance in the calculation of eye positions to improve medical diagnostics. Currently, there exists a prototype for the parameter-fitter and for the GRID enabled database. The screenshot below shows the Hess-Lancaster diagram-results of a parameter-fit for patient measured values (shown in green) and the fitted simulation (shown in red).
