Abstract: A method for simulating a deep-brain stimulation in a computer-assisted platform that includes providing to a neurosurgeon, through a man-machine interface, visual information of a pre-operative situation, including a representation of a brain. The method also includes monitoring inputs of said neurosurgeon on the man-machine interface, until a trajectory is determined between an entry point and a target for the placement of an electrode. The method further includes comparing said trajectory to a set of previously-established trajectories for the pre-operative situation, so as to determine an overall measurement representative of a quality of the trajectory compared to the previously-established trajectories.

Abstract: This invention relates to a method for simulating a deep-brain stimulation in a computer-assisted platform, comprising steps of: providing to a neurosurgeon, through a man-machine interface, visual information of a pre-operative situation, including a representation of a brain; monitoring inputs of said neurosurgeon on the man-machine interface, until a trajectory is determined between an entry point and a target for the placement of an electrode; comparing said trajectory to a set of previously-established trajectories for the pre-operative situation, so as to determine an overall measurement representative of a quality of the trajectory compared to the previously-established trajectories.

Abstract: A module for simulating an operative procedure within a virtual environment. The virtual environment is implemented by using a device for processing virtual environment data. The module includes: a module configured to obtain a data structure representing a set of objects of the virtual environment and having at least one relationship of interaction between at least two objects; a module configured to receive at least one scenario representing a procedure to be simulated, the scenario being defined on the basis of a descriptive ontology, the at least one scenario being obtained from at least one pre-determined procedural model; a module configured for the rendering, within the virtual environment, at least one portion of the scenario as a function of the set of objects of the virtual environment, the at least one procedural model and at least one action performed by at least one real user of the virtual environment.

Abstract: A method is provided for simulating a brain stimulation, delivering an estimation of a target spatial zone of stimulation. The method includes at least one iteration of the following acts: selection, from among at least two available values, of a value, referred to as a selected value, to be assigned to a pre-determined score; and identification, within an anatomo-clinical atlas belonging to a set of anatomo-clinical atlases, of a spatial zone capable of delivering a value close to said selected value to be assigned to said pre-determined score. The at least one iteration delivers a set of spatial zones. The method further includes a computation, as a function of the set of spatial zones, of at least one target spatial zone, capable of producing a given result representing at least one selected value.
