Abstract: A device for processing of data including images of a portion of a body includes processing means capable of processing first data representative of elementary portions of an image obtained by magnetic resonance in a region of the body and second data representative of elementary portions of images obtained by ultrasounds in a portion of that region, by performing: i) generating first and second maps of the probability that the elementary portions belong to structures of interest of the portion of the region based at least on the intensities associated thereto and respectively defined by the first and second data; ii) estimating a conversion for shifting from one of the first and second maps to the other while maximizing for each of their elementary portion the joined probability that it belongs to a same structure of interest; and iii) resetting the structures of interest of one of the first and second maps relative to those of the other by the conversion.

Abstract: A system for aiding in the positioning of a medical instrument on the head of a patient, characterized in that it includes a means for predicting the location of a target intracranial area of the medical instrument, comprising a generic three-dimensional model of a head comprising a scalp and a generic target intracranial area, a three-dimensional working image of the scalp of the head of the patient, surface registration means suitable for establishing a registration transform from the scalp of the generic model toward the working image of the scalp of the head of the patient, a means for resampling the generic target intracranial area into a converted target area using with the registration transform, and a means for locating the target intracranial area of the patient from the locating of the converted target area, thereby enabling the positioning of the medical instrument on the head of the patient.

Abstract: The invention relates to a device and to a method for cerebral location assistance. The device includes first and second memories. The first one is adapted for storing a generic mapping of the brain according to a first space location mode, as well as designation data corresponding to a target area in said mapping. The second one can receive and store, according to a second pace location mode, an operation image of the brain of an analysed subject acquired by medical imaging. The device also includes a non-rigid resetting tool adapted for establishing a conversion of the generic three-dimensional mapping towards the operation image, and a resampling tool for establishing a converted mapping with the converted designation data. A user's interface defines a visualization image that matches the operation image and the converted mapping while indicating an area that corresponds to the converted designation data.

Abstract: According to the invention, a device (D) is dedicated to the processing of data consisting of images of a portion or portions of a body, the device (D) includes processing means (MT) capable of, in the presence of first data representative of the elementary portions of an image obtained by magnetic resonance in a region of the body and of second data representative of the elementary portions of images obtained by ultrasounds in a portion of that region: i) generating first and second maps of the probability that the elementary portions belong to structures of interest of the portion of the region based at least on the intensities associated thereto and respectively defined by the first and second data; ii) estimating a conversion for shifting from one of the first and second maps to the other while maximising for each of their elementary portion the joined probability that it belongs to a same structure of interest; and iii) resetting the structures of interest of one of the first and second maps relative to
