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.
