DEVICE AND METHOD FOR CEREBRAL LOCATION ASSISTANCE
First Claim
1. A computer device for cerebral location assistance, comprising:
- a. a first memory device adapted for storing a general mapping of at least part of the brain according to a first spatial location mode, as well as designation data, established according to the first spatial location mode, and corresponding to a target zone area of the brain in said mapping;
b. a second memory device adapted to receive and store an operation image of at least part of the brain of an analyzed subject acquired by medical imaging, this operation image being stored according to a second spatial location mode;
c. a non-rigid registration tool adapted for establishing a registration transformation of a general three-dimensional mapping towards the operation image;
d. a resampling tool for establishing, according to the registration transformation, a converted mapping, in the format of the second spatial location mode, as well as converted designation data; and
e. a user interface, adapted to form a visualization image, which at least partially matches the operation image and the converted mapping, while indicating, in the visualization image, a zone that corresponds to the converted designation data.

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.

8. A method for cerebral location assistance, the method comprising the following steps:
-
a. charging a general three-dimensional brain mapping; b. preparing a designation of a brain zone on said general three-dimensional mapping; c. conducting electromagnetic wave imaging over at least part of the brain of an analyzed subject, to obtain an operation image; d. applying a non-rigid registration of the general three-dimensional map towards the operation image, to obtain a spatial geometric transformation making it possible to go from the general three-dimensional mapping towards the operation image; e. determining a target zone in the operation image from said designation of a brain zone in step b, and from the transformation in step d; and f. presenting an operator with a representation of the target zone of step e, for action on the target zone. - View Dependent Claims (9, 10, 11, 12, 13)
