Abstract In this paper, we aim to explore the mechanical potentialities of a material made an orthogonal net fibers arranged in logarithmic spirals. Therefore, annular plate described with second-gradient model is envisaged evaluate behavior such nonlinear elastic regime when large displacements and deformations occur. Several tests are performed numerically under finite element method approxim...

The mobility of soft tissue can cause inaccurate needle insertions. Particularly in steering applications that employ thin and flexible needles, large deviations can occur between pre-operative images of the patient, from which a procedure is planned, and the intra-operative scene, where a procedure is executed. Although many approaches for reducing tissue motion focus on external constraining ...

Breast lesion visibility in static strain imaging ultimately is noise limited. When correlation and related techniques are applied to estimate local displacements between two echo frames recorded before and after a deformation, target contrast increases linearly with the amount of deformation applied. However, above some deformation threshold, decorrelation noise increases more than contrast su...
