This paper presents an adaptive approach for 2D path planning of steerable needles. It combines dutycycled rotation of the needle with the classic RapidlyExploring Random Tree (RRT) algorithm and it is used intraoperatively to compensate for system uncertainties and perturbations. Simulation results demonstrate the performance of the proposed motion planner on a workspace based in ultrasound images.

An OpenURL link contains article metadata and directs it to the
OpenURL server of your choice. The OpenURL server can provide access
to the resource and also offer complementary services (specific
search engine, export of references...). The OpenURL link can be
generated by different means.
If your librarian has set up your subscription with an
