Title:
THERAPY APPARATUS FOR TREATING TISSUE BY EMISSION OF REMOTE CROSSED FOCUSED ULTRASOUND WAVES
Document Type and Number:
Japanese Patent JP2021159775
Kind Code:
A
Abstract:
To provide a therapy apparatus for treating tissue by the emission of focused ultrasound waves.SOLUTION: A creation surface of a pressure field of focused ultrasound waves is divided into at least N sectors having segments of asymmetrical concave curve with centres of curvature. Centres of curvature (c1, c2, ...) are asymmetrical where the centres of curvature are situated at different distances from a plane of symmetry A1 or from an axis of symmetry S and/or at different depths taken according to the axis of symmetry. Individual axes (a1, a2, ...) intersect between focal zones (Zc1, Zc2, ...) and the creation surface or beyond the focal zones such that a plurality of beams originating from the sectors create a focal coverage zone Zr which is off-axis relative to the plane of symmetry A1 or to the axis of symmetry S. The sectors of this creation surface creates energy deposit zones with profiles corresponding to the focal coverage zones.SELECTED DRAWING: Figure 4
