Patent number: 9918695Abstract: A method for measuring at least one property of biological tissue, including: positioning an ultrasonic transducer opposite the biological tissue to be measured; generating an ultrasonic signal within the biological tissue; acquiring at least one ultrasonic signal reflected by the biological tissue; determining at least one parameter of the biological tissue using the acquisition of the ultrasonic signal reflected by the biological tissue, the at least one parameter being representative of the biological tissue; comparing the at least one parameter of the biological tissue with at least one reference parameter of a target biological tissue so as to confirm the hypothesis of the presence of the target biological tissue opposite the ultrasonic transducer; and determining at least one property of the biological tissue on the basis of the result of the comparison. The method can be directly used in the field of humans or animals.Type: GrantFiled: September 17, 2010Date of Patent: March 20, 2018Assignee: EchosensInventors: Laurent Sandrin, Véronique Miette, Magali Sasso

Patent number: 8663111Abstract: The invention relates to an instrument for measuring the elasticity of a human or animal organ located behind the ribs. The instrument includes a casing having an actuator therein, the end of which is equipped with a transducer that is actuated in order to measure the elasticity of the organ. The measuring instrument also includes a mechanism for centering the transducer between the ribs.Type: GrantFiled: September 28, 2005Date of Patent: March 4, 2014Assignee: Echosens SAInventors: Laurent Sandrin, Jean-Michel Hasquenoph

Patent number: 8419642Abstract: A device configured to measure the viscoelastic properties of biological tissues using a processing of ultrasound waves reflected by these tissues when a shear wave runs across them is presented. The device includes memories for forming lines of data such that each line comprises data relative to the ultrasound waves reflected from the same shot and a calculator for determining a parameter relative to the displacement between the tissues and a transducer emitting the shots, a calculator for calculating an intrinsic displacement of the medium from a set of lines forming an acquisition, and a processor for processing the first ultrasound lines, by using the relative parameter, before or during the formation of second ultrasound lines from this same acquisition, in order to determine the intrinsic displacement of the biological tissues from these first lines.Type: GrantFiled: March 20, 2008Date of Patent: April 16, 2013Assignee: EchosensInventors: Laurent Sandrin, Sylvain Yon
