Randomized trial demonstrates optimal steering of flexible needles in soft tissue, suggesting improved access to targets.

This research aims to develop a motion planning algorithm for steering flexible needles through uncertain environments.
Developed a motion planning algorithm using dynamic programming for flexible needles.
Formulated the problem as a Markov decision process to account for uncertainties in tissue and needle mechanics.
Applied the algorithm to both deterministic and uncertain motion cases to generate motion plans.
Generated motion plans that effectively guide flexible needles to targets unreachable by rigid needles.
Demonstrated significant differences in planning outcomes when accounting for motion uncertainty.

Alterovitz et al. (2005) studied this question.
