Preoperative risk assessment for image based surgery planning often requires considerable technical and personnel resources especially for certain complex interventions, such as liver surgery. The purpose of the project SIMPL is to establish a distant service for specialized tasks in medical image analysis and the visualization of results.

Initially, the service is offered for risk assessment based on the analysis of CT and MR data to support surgery planning in oncologic liver resections and living donor liver transplantation.For the data transfer of the service request, the images and the results a free java client can be used. This allows for a secure transfer of data via the https protocol which is available with typical firewall configuration To explore the provided visualizations and quantification results an operating system independent viewing software is offered.For risk analysis the software packages HepaVision2 and InterventionPlanner developed by MeVis are used. The analysis software allows to extract, to analyze and to visualize organs, tumors and vascular trees, to calculate territories supplied or drained by parts of the vascular trees, calculate safety margins and territories at risk for resection proposals as well as volumes of resected parts and remnant.

As of April 2004 the service has been tested with 35 clinical partners from 11 countries in Europe, Asia and America. The cooperating hospitals usually use the web interface and the provided communication software which assist in the transfer of data and requests as well as in the download of results. 477 cases have been processed since December 2002 and results are currently provided within 2 to 72 hours.The hospitals consider the provided additional information to support the decision making process in intervention planning.

Results so far have shown that the provided service is feasible as planned and can be integrated into clinical workflow. Since many of our partners are interest in a similar support for planning of surgical interventions of the kidneys and pancreas first tests have been performed for renal tumors, living donor renal transplantation, and pancreatic tumors.
