A method and a system for anatomical site relocalisation using dual data synchronisation. Method for repositioning, possibly several times, at a specific location, which has been already explored during a first or 'reference exploration', a flexible endoscope during one or more successive endoluminal or extraluminal subsequent or 'new exploration', or similar procedures, wherein the repositioning is realized either manually, by a human user, or automatically, by a robotic system, from or by way of a synchronisation process between a &#x201c;new exploration&#x201d; flexible endoscope video and the &#x201c;reference exploration&#x201d; flexible endoscope video displayed in parallel on or in two different windows, on one or more screens.

Anatomical site relocalisation using dual data synchronisation

An automatic process of predictive determination of the position and movements of the skin of a subject in a zone of interest, with the subject breathing freely or in an assisted manner, includes preliminarily acquiring multiple configurations of the skin profile in axial planes, at given successive times, in different respiratory positions, and for each axial plane, constructing at least one deformable digital model starting from different skin profiles, then noting, in a repetitive manner, the actual position of a point on the skin at the level of each axial plane, whose position is significantly modified during inhalation and exhalation phases, and providing, essentially in real time, a simulation of the skin profile in each axial plane, as a function of the actual position noted, and an evolving three-dimensional representation of the skin at the level of the zone of interest, by interpolation between the different axial planes.

Automatic method of predictive determination of the position of the skin

A system for orientation assistance and display of an instrument that is inserted or present in the natural or artificially produced hollow cavity (human, animal, object), and that is equipped with one or more sensor units. Multiple measurements of the 3D position of the instrument equipped with one or more sensor units are performed by positioning a measuring system, so that a precise orientation and positioning of the instrument in the body can be computed. The 3D position data are used to compute a virtual image of the instrument synchronously. The virtual images are then either projected directly in exact position onto the body surface of a person or combined in a body surface image (real video camera image of the patient) onto a monitor or superimposed (virtual or augmented reality). The system is especially appropriate for displaying for a user a medical instrument, such as a catheter or a rigid or flexible endoscope, in the body of a person in real time, extracorporeally and in correct position.
