Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0051] In one example, see figure 1 , the elastography control method provided by this application can be applied to such as figure 1 shown in the application environment. The application environment includes a probe 102 , a material to be tested 104 and a focal point 106 generated by the probe 102 . Optionally, the probe may be an ultrasound probe. Specifically, taking an ultrasonic probe as an example, the ultrasonic probe emits a focused ultrasonic sound beam, which can apply an acoustic radiation force at the focal point 106 , and then excite a shear wave in the mat...

Abstract

The invention relates to an elastography control method. The method comprises: obtaining an ultrasonic image corresponding to a to-be-detected material; Performing image segmentation on the ultrasonicimage to obtain a plurality of image units; Acquiring an imaging area of a target tissue in the ultrasonic image according to the plurality of image units; If the imaging area of the target tissue issmaller than a preset area threshold value, generating first warning information, Wherein the first warning information is used for indicating to change the position of the probe or the position of the focus. The elastic imaging is carried out by adopting the mode, so that the to-be-measured material meets the rigid requirement of uniformity, and the influence of heterogeneity and material boundary on elastic wave propagation during measurement is avoided, therefore, the image quality of elastic imaging is improved, and the measured data is more accurate. The invention further relates to an elastic imaging control device, computer equipment, a computer readable storage medium and an elastic imaging system.

Description

technical field [0001] The present application relates to the technical field of elastography, in particular to an elastography control method and device, computer equipment, a computer-readable storage medium, and an elastography system. Background technique [0002] Shear wave elastography (Shear Wave Elastography) method is a new imaging method. In this method, a focused ultrasonic beam is emitted by a probe, and an acoustic radiation force can be exerted at the focal point, thereby exciting shear waves in human tissue. The propagation process of the shear wave inside the tissue can be observed by using the probe, and the propagation speed of the shear wave can be measured, wherein the propagation speed of the shear wave can reflect the magnitude of the shear modulus of the tissue. This method is non-invasive, fast, and can measure local mechanical properties, and is expected to play an important role in disease screening and physical examination. [0003] The tradition...
