A method of automatically meshing a volume of an object in an ultrasound imaging system comprises the steps of: acquiring image data of the object selecting a first surface of interest comprising a first slice of the object in the image data determining a main axis (AX) of the object defining a set of planes (22) separated by a given distance, being not parallel with the main axis while being parallel one with the other drawing a contour of the second slice of the object in at least two planes of the set of planes comprising a second slice of the object and meshing the volume by stacking the contours along the main axis according to the given distance.
