Embodiment Construction

[0048] figure 1 An ultrasonic imaging system for elasticity measurement in an embodiment is shown, the system includes a probe 10 , an ultrasonic imaging device 310 , a control and processing device 330 and a display device 350 .

[0049] The probe 10 includes a low-frequency oscillation driving device 110 and an ultrasonic transducer array 130 .

[0050] The low-frequency oscillation driving device 110 is used to generate vibration and form a shear wave propagating from the body surface to the inside of the tissue.

[0051] In this embodiment, the low-frequency oscillation driving device 110 is a low-frequency oscillator or a motor. In order to cause micro-deformation of biological tissue by external force or internal force, the vibration shaft 111 in the low-frequency oscillating driver 110 vibrates at low frequency and low amplitude, causing shear waves propagating into the biological tissue and inducing micro-deformation.

[0052]If the frequency of the shear wave in the...

Abstract

The invention relates to an ultrasonic imaging system for elasticity measurement. The ultrasonic imaging system comprises a probe, an ultrasonic imaging device, a controlling and processing device and a display device, wherein the probe comprises a low-frequency oscillation driving device for generating oscillation and forming a shearing wave propagating from human body surface to tissues, and an ultrasonic transducer array for sending an ultrasonic signal to the tissues and receiving an ultrasonic echo signal; the ultrasonic imaging device is used for driving the ultrasonic transducer array to send the ultrasonic signal and receive and process the ultrasonic echo signal according to loaded imaging parameters; the controlling and processing device is used for controlling the low-frequency oscillation driving device and the ultrasonic imaging device to process the ultrasonic echo signal so as to obtain a two-dimensional ultrasonic image and elasticity information of the tissues; and the display device is used for displaying the two-dimensional ultrasonic image and the elasticity information. The system and elasticity measuring method can simultaneously obtain the two-dimensional ultrasonic image and the elasticity information of the tissues, thereby improving clinical diagnosis accuracy; and the probe can realize precise positioning under the guiding of the two-dimensional ultrasonic image without considering displacement compensation, thereby improving convenience and accuracy of tissue elasticity measurement.

Description

【Technical field】 [0001] The invention relates to ultrasonic imaging technology, in particular to an ultrasonic imaging system for measuring elasticity and a method for measuring elasticity of biological tissue. 【Background technique】 [0002] Traditional B-mode ultrasound imaging is mainly used to obtain physiological structure information of biological tissues, and is not sensitive to early lesions, but the mechanical characteristics of biological tissues have changed significantly during early lesions. The mechanical characteristics such as elastic modulus (hardness) of biological tissues depend on the molecular composition and corresponding microstructure of biological tissues, and are closely related to their physiological and pathological characteristics. Diseased tissues and normal tissues often have mechanical characteristics such as elastic modulus (hardness) Therefore, the detection of changes in the mechanical characteristics of biological tissues can provide an i...
