PCSV team of the LPC laboratory in Clermont-Ferrand is involved in the deployment of biomedical applications on the grid architecture. One of these applications deals with the deployment of GATE (Geant4 Application for Tomographic Emission) for medical physics application. The aim of the developments actually performed is to enable the usage of the GATE platform in clinical routine. However, this perspective is only possible if the computing time is highly reduced as Monte Carlo GATE simulations applied to doses calculation in radiotherapy per example require several hours of calculations in order to achieve a precise result. The new grid architecture, developed within the framework of the European project Enabling Grid for E-sciencE (EGEE)[1] is there to answer this requirement. The use of the grid resources must be transparent easy and rapid for the medical physicists. For this purpose, we adapted the GENIUS web portal in order to facilitate the GATE simulations planning on the grid. The GENIUS development project started in 2002 was initiated by the Italian INFN Grid Project [4]. Its goal was to create a web portal that would overcome all the difficulties related to the complex command lines interfaces (CLI) and the job description language (JDL) that a user encounters when he has to submit his application in a grid environment. We describe first the architecture and implementation of the portal, the services offered and to finish the work realized (since April 2004) to customize the portal in order to allow transparent GATE jobs submission and management on the EGEE-LCG2 infrastructure. We present some results on the computing time demonstrating the impact of grid resources for the optimization of GATE.
