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.

10. 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

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
