The invention relates to a method of localisation of vector magnetometers arranged in a network, comprising the following steps: The invention also includes a magnetic field measurement instrument that includes a network of vector magnetometers and is capable of implementing the localisation method. Application to the imagery of biomagnetic fields, for example in magnetocardiography or in magnetoencephalography.

Vector magnetometers network and associated positioning method

A device for improving the precision of a biomagnetic image of a patient is provided. The device comprises a covering, a plurality of markers and at least five three-axis coils. Three-axis coils and markers of the plurality of markers are placed at the same location on the covering so that, when the covering is positioned on the patient, singular points of the part of the patient can be detected by magnetic resonance imaging and by biomagnetic imaging (MEG, MCG).

Multi-modal 3D marker for co-registration of biomagnetic and magnetic resonance imaging

The present description concerns a support helmet () for a medical imaging or treatment device, comprising a head cap () provided with a plurality of through openings (), each opening being adapted to receiving an elementary imaging or treatment module () assembled in the opening so as to slide along an axis substantially orthogonal to the head cap.

This processing method provides the ability to process a volume mode with an object intended to be added to or subtracted from said model. The volume model includes points arranged according to a spatial grid in a first reference system, each point being assigned an intensity value. The object has points positioned in a second reference system that is distinct from the first reference system. The method includes the calculation, for each point of the object, of an image point in the first reference system using a transfer function. The method further includes the modification of the intensity of points of the volume model by applying a correction function associated with each image point, the value of the correction function at a point of the volume model being dependent on the position of said point relative to said image point with which said correction function is associated.
