Embodiment Construction

[0017] The present invention will be described in more detail and complete below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention.

[0018] exist figure 1 In the process, the ultrasonic front-end equipment is used to scan the tissue, and the tissue signal carrying the external excitation is received and obtained. The ultrasonic front-end equipment sends the excitation signal through the displacement sensor, and uses the ultrasonic echo signal as the carrier of the excitation signal echo, and carries tissue information at the same time. The received RF signals of multiple ultrasonic cycles are arranged into a digital matrix, and the matrix image formed by the digital matrix is ​​analyzed. The specific way is:

[0019] By reading the original RF data and arranging them in the form of a data matrix, each column re...

Abstract

The invention discloses a strain diagram identification method based on ultrasonic transient elastography. The strain diagram identification method can be applied to identifying strain diagrams of body membranes, liver tissues and non-liver tissues. On the basis of the ultrasonic transient elastography and diagram processing, the obtained strain diagrams are analyzed through a series of algorithms, and the strain diagrams of the different tissues are identified and judged according to an algorithm processing result. The method includes the first method of diagram identification based on a strain diagram grey value, the second diagram identification method based on a strain diagram grey value turning rate and the third strain diagram identification method of filtering out border lines. Thecalculation result is subjected to statistic analysis, an optimal threshold value is selected to serve as the mark for the diagram identification, and the identification precision is improved.

Description

technical field [0001] The invention relates to a method for identifying a strain map of ultrasonic transient elasticity imaging, in particular to an ultrasonic transient elastic imaging method and a method for identifying a strain map generated by ultrasonic transient elasticity. Background technique [0002] In recent years, ultrasound imaging technology has become one of the most popular medical imaging technologies after X-ray imaging, layered scanning imaging, and nuclear magnetic resonance imaging technology. Ultrasonic imaging technology uses ultrasonic sound velocity to scan biological tissue, and obtains the image of biological tissue through the reception and processing of reflected signals, and reflects the characteristics of tissue by displaying the size, shape, edge and other information of the observed tissue. Information such as hardness and elasticity is less reflected. [0003] Ultrasonic transient elastography technology converts the elastic information of...
