A method of segmentation of a three-dimensional image for generating a model of a myocardial wall includes recording a three-dimensional image of a wall of the myocardium, the wall delimiting at least one cavity of the heart; segmenting a continuous part of the wall into at least a first volume having a thickness less than a first predefined thickness threshold of between 0 and 5 mm and a second volume of a continuous part of the wall having a thickness greater than the first threshold; generating a model of the wall of the myocardium, where the continuous part of the wall of the myocardium is modelled according to at least two volumes that continue each other.

A method for quantifying the presence of fats in a region of the heart includes an acquisition of an image of at least one cavity of the heart and of a wall; a selection of at least one pixel of a section through the heart including a density of pixels included in a first range of values; a growth in the selection of at least one pixel so as to define an extended 3D zone delimited by the cavity; an operation of homogeneous dilation of the extended 3D zone making it possible to define a dilated volume; an operation of extracting a peripheral region arising from the subtraction between the dilated volume and the extended 3D zone; a quantification of the number of pixels of a second range of values within the peripheral region.
