摘要： The probe has a transducer (1) for ultrasonic imaging of a medium (10), and another transducer (2) to generate mechanical constraint generating a transient modification of the medium. The transducers are operated in a coupled mode in which the transducer (1) is synchronized with the transducer (2) for imaging evolution of the transient modification of the medium. The transducer (2) has a geometric focalization that is far away than the transducer (1).

摘要： The method involves generating an interfacial acoustic radiation force (15) within a viscoelastic medium (11) i.e. biological medium, by applying acoustic waves i.e. ultrasonic waves, focused on an interface (13) i.e. artificial membrane, delimiting the medium (11) and an artificial medium (14) that possess distinct acoustic properties. The medium is imaged by using an ultrasonic sensor (12), in a rapid manner. The generation of the force is combined with the imaging of the medium such that propagation of mechanical waves that are generated in the medium, is imaged. An independent claim is also included for an artificial membrane for serving as an interface during implementation of a method of generating a mechanical transverse wave.

摘要： L'invention concerne un procédé et un dispositif d'imagerie d'un milieu viscoélastique [2]. Le procédé comprend les étapes d'excitation au cours de laquelle une contrainte mécanique interne est générée dans une zone dite d'excitation [A] et d'imagerie par acquisition de signaux pendant des mouvements engendrés par la contrainte mécanique dans le milieu viscoélastique [2] en réponse à la contrainte mécanique interne dans une zone dite d'imagerie [B] incluant la zone d'excitation [A]. Selon l'invention, il comprend en outre une étape de calcul d'un indice quantitatif [Cij] associé aux propriétés rhéologiques du milieu viscoélastique [2] en au moins un point [Bij] de la zone d'imagerie situé à une profondeur donnée hors de la zone d'excitation [A]. L'indice quantitatif [Cij] est représentatif d'une comparaison de signaux acquis pendant les mouvements engendrés en réponse à la contrainte mécanique en au moins un point [Ai] de la zone d'excitation [A] situé à la profondeur donnée avec des signaux acquis pendant les mouvements engendrés en réponse à la contrainte mécanique en au moins le point [Bij] de la zone d'imagerie [B] situé hors de la zone d'excitation [A].

摘要： The method involves performing excitation during which an internal mechanical constraint e.g. vibration, is generated in an excitation zone (A). Imaging is performed by acquiring signals during movements generated in a viscoelastic medium (2) e.g. ovary, based on the constraint in an imaging/observation zone (B). An quantitative index related to rheological properties is calculated in a point of the zone (B) situated at a depth outside the zone (A), where the index represents a comparison of the signals acquired during movements generated by a point of the zone (A) based on the constraint. Independent claims are also included for the following: (1) a rheological property imaging device comprising an excitation unit (2) a computer program comprising instructions for executing a method of imaging a rheological property of a viscoelastic medium (3) a recording medium comprising instructions for executing a method of imaging a rheological property of a viscoelastic medium.
