Touchless intra-operative display for interventional radiologist

International audience; Imaging records are an essential part of the overall management of patients due to undergo invasive interventional radiology (IR) or surgery. Imaging is needed for diagnosis, to confirm operability, plan the procedure, and as a per-operative guide [1]. In both IR and surgery, it is essential to be able to visualise and manipulate images from the workstation [2,3]. Current solutions, including the use of the PACS in operating theatres, are completely inadequate. The practice has become routine in interventional CT and the main manufacturers offer dedicated equipment to work with the imaging instrument and images [4]. The interface which offers the most is the use of a joystick to move the cursor on the screen in the same way as the conventional mouse. Manipulation, however, is imprecise and makes it slow and frustrating to use. Telecommand is easier to use but does not allow complex interactions. In reality, once the operator is under sterile conditions, working with pre-and per-operative imaging becomes extremely limited. In complex situations, it requires a third party (loading previous imaging, MR or PET-CT displays, multi-planar reformatting, zooming in onto an area of interest, etc.) sometimes leading to loss of concentration and loss of time [5].
