IMAGE PROCESSING DEVICE FOR MATCHING IMAGES OF A SAME PORTION OF A BODY OBTAINED BY MAGNETIC RESONANCE AND ULTRASOUNDS

摘要

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 those of the other by means of the conversion.
