The method of characterizing an ultrasound lesion (T) in organic tissues, the lesion being made by applying high intensity focused ultrasound delivered by a probe having its emission surface presenting a shape that is toroidal, consists in: after a period of at least two days from the end of ultrasound application, acquiring at least one characterization image (Ic) of the organic tissues; detecting the presence of a contrast border () in the characterization image (Ic); and from the contrast border (), determining the extent of the ultrasound lesion.

Method for characterising an ultrasound wound in organic tissues

The invention relates to a method for generating ultrasonic waves focused on a focal zone () in order to carry out biological lesions, comprising the activation of a plurality of ultrasonic transducer elements (). According to the invention:

Method and apparatus for generating focused ultrasonic waves with surface modulation

A therapeutic probe having a transducer for focusing the ultrasonic waves into a first focal area, the emission surface of which has, within a profile plane, two concave curve segments which have a finite length and which are symmetrical relative to a plane of symmetry, or to an axis of symmetry. Within the profile plane, both concave curve segments extend along arcs of first and second non-coincident circles that intersect each other, and each curve segment has an acoustic axis intersecting the axis of symmetry, or the plane of symmetry, between the first focal area and the emission surface, the acoustic axes being spaced apart from each other such that the beams from the emission surface intersect each other so as to create a second focal area located in and situated between the first focal area and the emission surface.
