Patent number: 10485516Abstract: Method for generating a shear wave in a target region of a soft solid, includes the following steps: a) generating at least two shear waves with a first and a second source of shear waves in the target region; b) detecting a propagation pattern of the shear wave in the target region with a detector unit including a row of ultrasonic transducers aligned on a first direction perpendicular to a detection direction of each or a single ultrasonic transducer movable along a first direction perpendicular to its detection direction; c) proceeding to a time reversal of the detected propagation pattern; and d) submitting the target region to an inverted excitation set of forces based on the temporally inverted propagation pattern. During step b), a first propagation pattern is detected when only the first source is active and a second propagation pattern is detected when only the second source is active.Type: GrantFiled: February 26, 2015Date of Patent: November 26, 2019Assignees: INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE (INSERM), Université Claude Bernard Lyon 1, Centre Léon-BérardInventors: Stefan Catheline, Remi Souchon, Ali Zorgani, Jean-Yves Chapelon

Patent number: 10368750Abstract: This shear wave imaging method, for collecting information on a target region (R) of a soft solid (S), comprises at least the steps a) of generating at least one shear wave (SW) in the target region, and b) of detecting a propagation pattern of the shear wave in the target region. Step a) is realized by applying to particles of the target region (R) some Lorentz forces resulting from an electric field (E) and from a magnetic field (B). At least one of the electric field (E) and the magnetic field (B) is variable in time, with a central frequency (fo) between 1 Hz and 10 kHz. Alternatively, both the electric and magnetic fields (E, B) are variable in time, with a central difference frequency (?fo) between 1 Hz and 10 kHz. The shear wave imaging installation comprises a first system (4, 7) for generating at least one shear wave (SW) in the target region (R) and a second system (10) for detecting a propagation pattern of the shear wave.Type: GrantFiled: July 10, 2014Date of Patent: August 6, 2019Assignees: INSERM (Institut National de la Santé et de la Recherche Médicale), Université Claude Bernard Lyon 1Inventors: Stefan Catheline, Jean-Yves Chapelon, Remi Souchon, Pol Grasland-Mongrain, Cyril Lafon

Step a) is performed by exciting a first ultrasonic transducer (401) with a first excitation signal (S401) during at most 50 ms, step b) is performed by exciting a second ultrasonic transducer (402) with a second excitation signal (S402) during at most 0.Type: ApplicationFiled: November 25, 2016Publication date: December 6, 2018Inventors: Stefan CATHELINE, Jean-Yves CHAPELON, Cyril LAFON

Patent number: 7511711Abstract: Apparatus and methods for locating an impact point on a surface of an object. The object is provided with an acoustic sensor that senses the impact from the acoustic waves that are generated when the object is subjected to the impact. The location of the impact on the surface of the object is determined by a recognition step that includes a comparison of the sensed signal to one or more predetermined signals. Each predetermined signal represents an active zone on the surface of the object. A predetermined signal corresponds to the sensed signal when the impact causing the sensed signal is generated in the active zone represented by the predetermined signal. The impact is associated with the active zone represented by a predetermined signal when the sensed signal and the predetermined signal sufficiently correspond to each other.Type: GrantFiled: December 28, 2004Date of Patent: March 31, 2009Assignee: Sensitive ObjectInventors: Ros Kiri Kiri Ing, Stefan Catheline, Nicolas Quieffin, Mathias Fink

Patent number: 6770033Abstract: The invention concerns an image method for observing the propagation of low-frequency shearing pulse wave simultaneously in multiple points of a diffusing viscoelastic medium. The method consists in transmitting at a very high rate ultrasonic compression waves enabling to obtain a succession of images of the medium; then in delayed processing of the resulting images by intercorrelation to determine in each point of each image the movements of the medium while the shearing wave is being propagated.Type: GrantFiled: January 8, 2002Date of Patent: August 3, 2004Assignee: Societe d'Elastographie Impulsionnelle pour les Systemes de Mesure de l'Elasticite (SEISME)Inventors: Mathias Fink, Laurent Sandrin, Michaël Tanter, Stefan Catheline
