Elastic imaging is a technique for converting the elastic modulus of soft tissues to real-time computer images. As one of the branches of elastic imaging, tactile imaging is distinguished by the feature of pressing directly against the surface of soft tissues. It is a mature option to diagnose diseases in urology, general surgery, gynecology and obstetrics. In recent years, tactile imaging, especially vaginal tactile imaging, has been used to evaluate female pelvic floor dysfunction diseases.
