摘要:
Device for focusing pulses comprising at least emitting means comprising a network (5) of transducers (6), these emitting means being adapted to make the network of transducers emit, into a reflective cavity (7), at least one wave focused onto at least one target point (4) of a target medium (2). The reflective cavity comprises a multi—scattering medium (8) adapted to cause multiple scattering of said wave.

The invention concerns a detecting apparatus (12) for imaging at least two areas of a brain of a subject (10), the detecting apparatus (12) comprising:—a holder comprising:—a frame (14) devoted to be cemented on the skull of the subject (10), the frame (14) delimitating an inner portion (18) which is transparent to ultrasound waves,—a removable imaging device comprising:—a platform (16) delimitating an inner space (28), the inner space (28) facing the inner portion (18),—a fixing element (30) adapted to temporary fix and lock the platform (16) to the holder,—an ultrasound probe (32), and—a moving stage (34) holding the ultrasound probe (32) and being adapted to move the ultrasound probe (32) within the inner space (28).
摘要:
The present invention concerns a method for obtaining a functional parameter of a muscle having a part, the method comprising the steps of: a) applying ultrasound waves to the muscle, b) collecting the ultrasound waves retrodiffused by the muscle at a plurality of times, to obtain collected ultrasound waves, c) determining a first plurality of values representative of stiffness values of one part at a first plurality of times by using the collected ultrasound waves, d) determining a second plurality of values representative of deformation values of said part at a second plurality of times by using the collected ultrasound waves, and e) deducing at least one functional parameter based on the first plurality of values and the second plurality of values. The invention also concerns a corresponding device.
摘要:
The invention relates to a method for obtaining a numerical model, the numerical model associating at least one objective measurement to a subjective sensation, the method comprising the steps of: a) imaging the at least one area of the brain by using unfocused waves produced by a transcranial ultrasound probe (20), to obtain at least one acquired image of the activity of the area, b) evaluating a physical quantity representative of the activity of the at least one area based on the acquired images, to obtain at least one objective measurement, c) obtaining from the subject at least one numerical value representative of a subjective sensation, and d) determining the numerical model by using the obtained objective measurement and the obtained numerical value.
摘要:
The invention concerns a detecting apparatus (12) comprising:—at least two sensors (24, 26, 28), with at least one sensor (24) being an ultrasound transducer adapted to produce ultrasound waves, and—a positioning device (16) defining several compartments (22), each compartment (22) being adapted to hold a sensor (24, 26, 28) and each compartment (22) being located at predetermined location, the positioning device (16) comprising a holder adapted to be fixed on the skull of a subject, the positioning device (16) being adapted to be maintained on the head of the subject using the holder.
摘要:
Method for measuring a physical parameter in soft tissues of a mammal, in which a mechanical shear wave is propagated through the soft tissues and observation of the propagation leads to determine values of a shear wave propagation parameter. The physical parameter is computed on the basis of these values.
