SYSTEMS AND METHODS FOR MEASURING ELASTICITY WITH VISUALIZATION OF ULTRASONIC MULTIFOCAL SHEAR WAVES IN MULTIPLE MEASUREMENTS Russian patent published in 2024 - IPC A61B8/00 A61B8/08 A61N7/00 

FIELD: medicine; measuring.

SUBSTANCE: system for measuring elasticity of material, comprising: an ultrasonic measuring sensor comprising an ultrasonic transducer configured to supply ultrasonic beams to the material, wherein the material has elasticity; an ultrasonic imaging system configured to visualize shear waves; electronic processing system configured to obtain characteristics of visualized shear waves and determining the elasticity of the interrogation region of the material based on the obtained characteristic. Method for non-invasive measurement of elasticity of material, including: connection of ultrasonic measuring sensor with material; supply of ultrasonic beams from ultrasonic transducer into material; focusing ultrasonic beams on focal areas in the material; generation and visualization of shear waves; obtaining a characteristic of the visualized shear waves and determining the elasticity of the interrogation region of the material based on the obtained characteristic. Method of measuring elasticity of material by creating simultaneously existing focal points, including: connecting the measuring sensor of the ultrasonic transducer to the surface of the material; focusing to obtain separate focal zones located at a distance from each other; obtaining characteristics of shear waves; determination of the interrogation area elasticity below the skin surface.

EFFECT: providing feedback on the effectiveness of therapeutic exposure using directed and precision ultrasound to achieve a visible and effective result through exposure to heat by dividing the beam for ultrasound therapy into two, three, four or more simultaneously existing focal zones for performing various processing and/or imaging procedures.
