Resolution Optimal Motion Planning for Medical Needle Steering from Airway Walls in the Lung

ICRA 2025

Steerable needles are novel medical devices capa-ble of following curved paths through tissue, enabling them to avoid anatomical obstacles and steer to hard-to-reach sites in tissue, including targets in the lung for lung cancer diagnosis. Steerable needles are typically deployed into tissue from an

Landmark Based Bronchoscope Localization for Needle Insertion Under Respiratory Deformation

IROS 2023poster

Bronchoscopy is currently the least invasive method for definitively diagnosing lung cancer, which kills more people in the United States than any other form of cancer. Successfully diagnosing suspicious lung nodules requires accurate localization of the bronchoscope relative to a planned biopsy sit…

A Metric for Finding Robust Start Positions for Medical Steerable Needle Automation

IROS 2022poster

Steerable needles are medical devices with the ability to follow curvilinear paths to reach targets while circumventing obstacles. In the deployment process, a human operator typically places the steerable needle at its start position on a tissue surface and then hands off control to the automation…

Backward Planning for a Multi-Stage Steerable Needle Lung Robot

RA-L 2021

Lung cancer is one of the deadliest types of cancer, and early diagnosis is crucial for successful treatment. Definitively diagnosing lung cancer typically requires biopsy, but current approaches either carry a high procedural risk for the patient or are incapable of reaching many sites of clinical

Design Considerations for a Steerable Needle Robot to Maximize Reachable Lung Volume

ICRA 2021poster

Steerable needles that are able to follow curvilinear trajectories and steer around anatomical obstacles are a promising solution for many interventional procedures. In the lung, these needles can be deployed from the tip of a conventional bronchoscope to reach lung lesions for diagnosis. The reach…
