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

11. 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
