20090099448 | Human or animal organ imaging system which can be used to measure the elasticity of the organ - A system and method are provided for an imaging system that may be used to measure the elasticity of an organ. In the system, an electronic transducer forms an image of a human or animal organ. A mobile part may be moved in translation or rotation, and is arranged to induce the propagation of low frequency vibration in the direction of the organ when actuated. The mobile part delivers the vibrational energy against the human or animal body. The transducer has a fixed part that also emits similar energy. By application of energy to the mobile and fixed parts, and by collection of energy, a control and calculation module may compute parameters of internal organs, such as elasticity. | 04-16-2009 |
20100130865 | DEVICE FOR MEASURING THE VISCOELASTIC PROPERTIES OF BIOLOGICAL TISSUES AND METHOD USING SAID DEVICE - 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 means for forming lines of data such that each line comprises data relative to the ultrasound waves reflected from the same shot and means for determining a parameter relative to the displacement between the tissues and a transducer emitting the shots, means for calculating an intrinsic displacement of the medium from a set of lines forming an acquisition, and means 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. | 05-27-2010 |
20110004104 | DEVICE AND METHOD FOR MICRO-ELASTOGRAPHY - Device and method associated with vibration micro-elastography for qualitative and/or quantitative measurements of viscoelastic properties, such as the elasticity and/or the viscosity of a viscoelastic medium and more particularly of a human or animal biological tissue, carried out inside the human or animal body. This method may be carried out with the aid of a probe inserted into the human or animal body, which probe is connected to an external controller via a threadlike tube. | 01-06-2011 |
