ABSTRACT:
Methods for characterizing elasticity of vaginal tissue are provided. A transvaginal probe is used to deform vaginal tissue during examination. The probe is equipped with pressure sensors and a motion tracking sensor. Stress and strain data is recorded during examination. Elasticity of vaginal tissue is then characterized by calculating a stress gradient defined as a ratio of stress over strain for each point of measurement. Vaginal tactile image may also be compiled to include a family of surfaces representing locations of measurement points at predefined constant levels of stress. Pelvic organ abnormality condition may be detected if the stress gradient is below either a predetermined threshold or a normal stress gradient obtained from clinical data.
