  • Patent number: 10524812
    Abstract: A method for locating and visualizing a target (C) in relation to a focal point (F2), in a mammal, particularly a human body, including the steps of forming an ultrasound probe mobile in space, mechanically independent of a treatment system and located by a remote locating system, ensuring simultaneous recording firstly of an ultrasound image in which the image of the target appears, and secondly of the position of the ultrasound probe, in the recorded ultrasound image, selecting the position of the image of the target to determine the virtual position of the target (C), simultaneously determining firstly the position of the focal point (F2) by the remote locating system, and secondly the position of the members displacing the target and/or treatment system, and calculating the displacement values for the displacing members, to cause the virtual position of the target (C) to coincide with the focal point (F2).

  • Patent number: 10327732
    Abstract: 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 (16) in the characterization image (Ic); and from the contrast border (16), determining the extent of the ultrasound lesion.

  • Publication number: 20180177519
    Abstract: The invention relates to a method for generating ultrasonic waves focused on a focal zone (5) in order to carry out biological lesions, comprising the activation of a plurality of ultrasonic transducer elements (3). According to the invention: a target zone, in which homogenization of the supply of energy of the ultrasonic waves emitted by the ultrasonic transducer elements is desired, is chosen, the focusing effect and the acoustic attenuations of the ultrasonic waves on their path between the target zone and the ultrasonic transducer elements (3) are determined, the focusing effect and the acoustic attenuations of the ultrasonic waves are compensated, with ultrasonic transducer elements (3) at least some of which have non-identical emission surfaces such that in the target zone, the supply of energy of the ultrasonic waves emitted by the different ultrasonic transducer elements (3) is more or less identical.

  • Patent number: 10004922
    Abstract: The object of the invention relates to an apparatus for the thermal treatment of biological tissues by means of the application of focused ultrasound waves, the apparatus including: a probe movement system for ensuring: the moving of the focal zone along a first direction, from a distal point of the treatment zone to a proximal point of the treatment zone, in order to create a sequence of elementary treatment zones; the juxtaposition of sequences of elementary treatment zones in order to completely cover the treatment zone; a control circuit controlling the probe, in order to ensure that the ultrasonic power delivered to the focal zone decreases between the distal point and the proximal point of the treatment zone.

  • Patent number: 9737324
    Abstract: 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.
