Embodiment 1

[0049] Please refer to figure 1 , the ultrasonic elasticity measurement device 100 includes an ultrasonic probe 101 , a transmit / receive sequence control module 102 , an echo processing module 104 , a processor 105 , a memory 103 and a display 106 . The processor 105 is connected to the transmit / receive sequence controller 102, the memory 103 and the display 106 respectively, the ultrasonic probe 101 is connected to the transmit / receive sequence controller 102, the ultrasonic probe 101 is also connected to the echo processing module 104, and the echo processing module 104 The output terminal of is connected to the processor 105. The device also includes a human-computer interaction device. The user interacts with the image output on the display through the human-computer interaction device, and inputs operation instructions about the selection or movement of the region of interest and / or target region to the processor. The human-computer interaction device includes: Mouse, ke...

Embodiment 2

[0082] The difference between this embodiment and the first embodiment is that the sign value representing the particle's degree of interference is the signal-to-noise ratio of the particle acceleration curve, and the signal-to-noise ratio refers to the ratio of signal to noise. When the signal-to-noise ratio of the acceleration curve is larger, it means that the acceleration curve is less affected by the noise, so the signal-to-noise ratio can also represent the degree to which the particle is affected by interference. In this embodiment, the calculation process of the signal-to-noise ratio is as follows Figure 9 shown, including the following steps:

[0083] Step 20, find the maximum amplitude of the acceleration curve. like Figure 10 As shown, search on the acceleration curve, find point A in the figure where the maximum amplitude of the acceleration curve is located, and obtain the amplitude of this point.

[0084] Step 21, select a comparison curve segment on the acc...

Abstract

The invention discloses an ultrasonic elastic imaging device and an elastic imaging result evaluation method. A first ultrasonic wave used for detecting shear waves in a region of interest is transmitted to the region of interest in biological tissues to obtain first ultrasonic echo data. According to the first ultrasonic echo data, on the one hand, an elastic distribution image is generated, andon the other hand, credibility information of a target region is calculated in order to enable a doctor to intuitively understand the credibility of a current shear wave elasticity result, so that thedoctor can judge whether the current shear wave elasticity result is acceptable or not according to the credibility information, or make a comprehensive judgment on the condition of a patient according to the current shear wave elasticity result and the credibility information thereof.

Description

technical field [0001] The invention relates to ultrasonic equipment, in particular to an ultrasonic elastic imaging device and an evaluation method for elastic imaging results. Background technique [0002] Ultrasound elastography is one of the hotspots of clinical research in recent years. It mainly reflects the elasticity or softness of tissues. [0003] The conventional ultrasound elastography method mainly produces a certain deformation by pressing the tissue with the probe, and then calculates and images parameters related to tissue elasticity such as strain amount and strain rate, which indirectly reflects the elastic difference between different tissues. Since the strain result is sensitive to pressure, and it is difficult to maintain consistent pressure for each operation, it is difficult to guarantee the repeatability and stability of imaging. [0004] The shear wave imaging method mainly reflects the difference in hardness between tissues by generating shear wave...
