Provided is a system and method for estimating the motion of a target inside a tissue based on surface deformation of the soft tissue. The system consists of an acquisition unit, a reference input unit, two surface extraction units, a target position extraction unit, a feature calculation unit, and a target motion estimation unit. The method includes: the acquisition unit acquires an image Iof the soft tissue; the surface extraction unit extracts a surface fof the soft tissue from I; the reference input unit acquires a reference image Iof the soft tissue; the surface extraction unit and the target position extraction unit respectively extract a reference surface fof the soft tissue and a target reference position tfrom I, the feature calculation unit calculates deformation feature Ψof frelative to f, the target motion estimation unit estimates the target displacement based on Ψand t.
