ULTRASOUND IMAGING METHOD FOR MEASURING ELASTIC CHARACTERISTICS OF MEDIUM BY MEANS OF VARIATION OF SPECKLE PATTERNS

摘要

The present invention relates to a method for measuring the elastic properties of the medium in the ultrasound image, and particularly a method of estimating by measuring the acoustic properties of the medium, a change in the speckle pattern in ultrasonic images. Method for measuring the acoustic properties of the medium in the ultrasound images, with respect to the step of applying the vibration with respect to the medium, the method comprising: obtaining a plurality of ultrasound image frames with respect to the medium receiving the vibration, a given pixel in the plurality of image frames calculating a change amount of the brightness is large on the Spanish pattern time axis, and a step of measuring the elasticity of the medium by using the luminance change of the calculated speckle patterns.
