Mathematical modeling and computer simulation of needle insertion into soft tissue
Fig 21
Modeling of needle insertion (insertion depth of 15 mm) into the non-homogenous cylindrical (diameter of 65 mm and height of 34 mm) sample of Sylgard 527 gel.
Vector plot of the predicted (red vectors) using our model and experimentally determined from the CT image analysis (blue vectors) displacement field at the beads’ location. The gel sample is shown in Fig 6, and the experimental set-up—in Fig 7.
