Background
At present, the ultrasonic elastography is a novel ultrasonic diagnosis technology, can be used for researching tumor and diffused disease imaging which cannot be detected by the traditional ultrasound, and can be applied to the aspects of mammary gland, thyroid gland, prostate and the like. The working principle of the ultrasonic elastography is that an ultrasonic probe is used for tightly pressing a lesion part to compare pressure data of elastic information before and after pressurization. The basic principle of ultrasonic elastography, which is to help the diagnosis of diseases by using the elasticity information of biological tissues, is as follows: according to the different elastic coefficients of different tissues, the strain is different after external force or alternating vibration is applied. Under the same external force action, the elastic coefficient is large, and the induced strain ratio is small; conversely, the elastic coefficient is smaller, and the corresponding strain is larger. The ultrasonic elastography utilizes the difference of elastic coefficients between a tumor or other lesion areas and surrounding normal tissues to generate the difference of strain magnitude, and the difference is displayed by color coding to judge the elastic magnitude of the lesion tissues, thereby deducing the possibility of certain lesions.
