Embodiment approach

[0053] Such as figure 1 As shown, the image processing method of the present application, an embodiment thereof, comprises the following steps:

[0054] Step 102: Obtain the region of interest in the ultrasound elastic image on the ultrasonic diagnostic instrument, the region of interest includes a small nodule with rear echo attenuation.

[0055] Using Mindray Resona7 ultrasonic diagnostic instrument, 11-3M linear array probe, frequency range 3-11MHz. On the same day, routine ultrasonography was first performed, and the location, size, shape, boundary, echo, calcification, rear echo, and blood flow characteristics of the nodule were observed and recorded. Then turn on the ultra-wide beam tracking technology and enter the elastic STE imaging mode to ensure that all the maximum sections of nodules enter the ROI (region of interest) frame, and turn on the credibility map to help observe the stability of elastic motion and obtain the shearing of nodules. Ultrasound elasticity i...

Abstract

The invention relates to an image processing method and device. The image processing method comprises the following steps of obtaining regions of interest in ultransonic elastic images on an ultrasonic diagnostic apparatus, wherein the regions of interest comprise a small nodule with rear echo attenuation; outlining the outline range of the small nodule with rear echo attenuation, and measuring anE value and a G value; performing elastic modulus analysis on the regions of interest through the E value and the G value; drawing an ROC curve to obtain ROC area under curve and a best cut off point; and according to the cut off point, performing assessment on the small nodule with rear echo attenuation. According to the image processing method disclosed by the embodiment of the application, inreal-time shear wave elastic imaging, the shear modulus E value and G value are utilized to distinguish the small nodule with rear echo attenuation, the E value and the G value of benign nodules and malignant nodules in the mammary gland with rear echo attenuation are measured, and tissue morphological structure information provided by ultransonic is combined with elastic E imaging hardness information, so that tumor diagnosis accuracy is improved.

Description

technical field [0001] The present application relates to image processing, and in particular to an image processing method and device. Background technique [0002] In the Breast Imaging Reporting and Data System (BIRADS) dictionary, "rear echo attenuation" is one of the words used to describe malignant breast tumors. Classical ultrasound medical books also classify rear echo attenuation as an ultrasound feature of malignant breast lesions. Therefore, in the past Sonographers who see nodules with such characteristics will classify them as breast cancer. In fact, many nodules with posterior echo attenuation are benign lesions, and benign and malignant nodules with posterior echo attenuation have common features on sonograms, making it difficult to differentiate and diagnose. Contents of the invention [0003] The present application provides an image processing method and device. [0004] According to the first aspect of the present application, the present application p...
