Realistic modeling of needle insertion during brachytherapy can be used for training and in automated planning to reduce errors between intended and actual placement of the needle tip. We have developed a three-dimensional tetrahedral finite element simulation that models tissue deformation, needle flexation, and their coupled interaction.
