A Digital Twin for Robotic Post Mortem Tissue Sampling Using Virtual Reality

Maximilian Neidhardt, Ludwig Bosse, Vidas Raudonis, Kristina Allgoewer, Axel Heinemann, Benjamin Ondruschka +1
ICRA 2026poster

Studying tissue samples obtained during autopsies is the gold standard when diagnosing the cause of death and for understanding disease pathophysiology. Recently, the interest in post mortem minimally invasive biopsies has grown which is a less destructive approach in comparison to an open autopsy a…

Collaborative Robotic Biopsy with Trajectory Guidance and Needle Tip Force Feedback

Robin Mieling, Maximilian Neidhardt, Sarah Latus, Carolin Stapper, Stefan Gerlach, Inga Kniep +3
ICRA 2023poster

The diagnostic value of biopsies is highly dependent on the placement of needles. Robotic trajectory guidance has been shown to improve needle positioning, but feedback for real-time navigation is limited. Haptic display of needle tip forces can provide rich feedback for needle navigation by enablin…

Optical coherence tomography based 1D to 6D eye-in-hand calibration

Sven-Thomas Antoni, Christoph Otte, Thiusius Rajeeth Savarimuthu, Omer Rajput, Alexander Schlaefer
IROS 2017poster

Optical coherence tomography (OCT) is an interferometric imaging modality with spatial resolution in the micrometer range. The OCT signal can be used to detect small structures to measure deformation or to characterize tissue. Moreover, OCT can be realized through a single optical fiber, i.e., it ca…
