Medical device and method for processing microwave medical images by means of descriptors of 3d shape and of texture characteristics in order to characterize lesions in imaged tissues

Abstract

The invention relates to a method for processing medical images of human tissues of a zone of the body of a patient and in particular of the breast by means of a microwave medical imaging device, the method comprising the following steps implemented in a processing unit of the medical imaging device:—identifying at least one region of interest using at least one initial microwave image of a zone of the body of a patient;—processing each region of interest identified in an image so as: o to determine at least a first shape characteristic, preferably the solidity of each region of interest; o to determine at least a second and third characteristics relative to the texture of each region of interest; the first, second and third characteristics being coordinates characterising each region of interest;—locating, in a space of at least three dimensions, the dimensions of which are at least the first, second and third characteristic, respectively, each region of interest based on its coordinates, the space being partitioned by a decision hypersurface into two continuous and separate sub-spaces, one sub-space such that a region of interest located therein is associated with a benign lesion, and another sub-space such that a region of interest located therein is associated with a malignant lesion.
