Optical Fiber-Based Needle Shape Sensing in Real Tissue: Single Core vs. Multicore Approaches [PDF]
arXiv, 2023 Flexible needle insertion procedures are common for minimally-invasive surgeries for diagnosing and treating prostate cancer. Bevel-tip needles provide physicians the capability to steer the needle during long insertions to avoid vital anatomical structures in the patient and reduce post-operative patient discomfort.

Revista da Sociedade Brasileira de Medicina Tropical, 1997 Often in tropical practice there is not time or conditions to do a proper autopsy on a patient who has died. A needle biopsy technique is described for limited closed autopsy examination to clariffy organ histology. In this way the clinician may resolve puzzling fatal disease.

Motion Informed Needle Segmentation in Ultrasound Images [PDF]
arXiv, 2023 Segmenting a moving needle in ultrasound images is challenging due to the presence of artifacts, noise, and needle occlusion. This task becomes even more demanding in scenarios where data availability is limited. In this paper, we present a novel approach for needle segmentation for 2D ultrasound that combines classical Kalman Filter (KF) techniques ...

Collaborative Robotic Biopsy with Trajectory Guidance and Needle Tip Force Feedback [PDF]
2023 IEEE International Conference on Robotics and Automation
(ICRA), London, United Kingdom, 2023, pp. 6893-6900, 2023 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 enabling localization of tissue structures along the ...
