ABSTRACT = {In order to get to the desired target inside the body, it is essential to investigate 
the needle-tissue coupling process and calculate the tissue deformation. A cantilever 
beam model is presented to predicting the deflection and bending angle of flexible needle 
by analyzing the distribution of the force on needle shaft during the procedure of needle 
insertion into soft tissue. Furthermore, a finite element (FE) coupling model is proposed
to simulate the needle-tissue interactive process. The plane and spatial models are created 
to relate the needle and tissue nodes. Combined with the cantilever beam model and the
finite element needle-tissue coupling model, the simulation of needle-tissue interaction 
was carried out by the ABAQUS software. The comparing experiments are designed to 
understand the needle-tissue interactions, by which the same points in the experiments 
and simulation are compared and analyzed. The results show that the displacements in x 
and z directions in the simulation can accord with the experiments, and the deformation 
inside the tissue mainly occurs in the axial direction. The study is beneficial to the robotassisted and virtual needle insertion procedure, and to help the physicians to predict the 
inside tissue deformation during the treatments.},
