description
The XLcloud project strives to establish the demonstration of a High Performance Cloud Computing (HPCC) platform based on OpenStack that is designed to run a representative set of compute intensive workloads. Two Use Cases will be demonstrated during this presentation. First, the interventional radiology use case of the XLCloud project has the goal to show that the XLCLoud platform can be used to leverage an application requiring both interaction and high performance computing. This simulator, developed by CEA and Esprimed, allows medical staff to prepare or replay an intervention in a 3D interactive environment (manipulation of the radiological system, position of people and their protections) while having the benefit of precise estimation of the dose they are exposed to through a 3D monte carlo simulation optimized in order to provide results in interactive time. The second use case will be based on cloud gaming and 3D visualization. XLcloud is a three-year long collaborative project funded by the French FSN (Fonds national pour la Société Numérique) programme.

Interventional radiology
Ø Interventional radiology is a medical sub-specialty of radiology which utilizes minimally-invasive image-guided procedures to diagnose and treat diseases in nearly every organ system (Wikipedia)
Ø This means that surgeon and medical staff are always exposed to X-rays
Ø This is becoming a world wide issue raised by safety authorities

The Esprimed interventional radiology training tool
Esprimed is a young company focused on best practices in interventional radiology
Advices/formation for medical teams Minimization of dose received by patient and medical team
Esprimed asked CEA to develop a virtual reality demonstrator including
Movement of the radiologic system Movement of radiologic protections Computation of Dose receive by the surgeon Ability to replay a complete sequence
à Rich interaction Radiology equipment through the web Protection screen moved through space mouse 3D view controlled through mouse Imaging commands through keyboard
à Intensive computation Real time estimation of dose | PAGE 11
