It is the dynamic/static state/quasi-static excitation for applying inside (including itself) or outside to tissue, in Elasticity, life
Under the effect of the physics laws such as material resources, tissue will produce a response.Due to different tissues (including normal and pathological tissue)
Coefficient of elasticity (stress/strain) is different, and its strain size is also different after by external force pressure.To the echo before and after tissue deformation
Signal carries out image conversion processing, the elastic size of tissue is intuitively shown by the color of image, so that lesion.
At present, tried one's best accurately to ensure the elastomeric check result of tissue, it usually needs tissue is carried out that survey is repeated several times
Amount, to obtain final elastomeric check result.I.e. operator will pop one's head in and be placed in after the relevant position of tissue, start one-shot measurement,
Relevant treatment is carried out by main frame again and obtains an elastomeric check result, then probe is placed in the relevant position of tissue again,
Restart one-shot measurement, obtain second elastomeric check result, and so on, the elasticity inspection of last comprehensive repeatedly (at least eight times)
Survey result and obtain final elastomeric check result.
Inventor realize it is of the invention during find prior art defect be：Set by existing elastomeric check
It is standby when carrying out repeated detection to patient, it is necessary to doctor carries out manually booting probe respectively for repeated detection measures.Work as inspection
When survey number of times is ten even more multiple several times, carries out ten manually respectively and even more repeatedly start the behaviour that probe is measured several times
Make so that detection time is more long, during this period, doctor needs to be detected with anchor hand hold transducer for a long time, it is easy to
Causing the site tissue damages such as shoulder doctor in detection time more long needs hand hold transducer to keep longer time, so as to easily lead
Shoulder is caused to be damaged.Meanwhile, patient is difficult to keep anchor in detection time more long, causes repeated detection position not solid
It is fixed, and cause the problem of testing result bigger error.
