Embodiment Construction
[0023] see figure 1 , a method for extracting tumor elasticity features of elastography, the specific steps are as follows:
[0024] Step S10: Input medical images and elastic images.
[0025] Elastic imaging technology is a relatively mature imaging technology, according to which elastic images can be obtained, and medical images can be B-ultrasound images or CT images or MRI (magnetic resonance) images or X-ray (X-ray) images, in the present invention In the provided embodiments, the medical image is preferably a B-ultrasound image.
[0026] Step S20: preprocessing the medical image.
[0027] see figure 2 , the flow chart of B-ultrasound image preprocessing provided by the embodiment of the present invention, step S20 is specifically:
[0028] Step S21: Perform speckle noise filtering processing on the medical image.
[0029] The coherent nature of ultrasound imaging leads to inherent speckle noise in B-ultrasound images. Speckle noise reduces the image quality, especi...
