Endpoint Accuracy in Manual Control of a Steerable Needle.
PURPOSE To study the ability of a human operator to manually correct for errors in the needle insertion path without partial withdrawal of the needle by means of an active, tip-articulated steerable needle. MATERIALS AND METHODS The needle is composed of a 1.32-mm outer-diameter cannula, with a flexure joint near the tip, and a retractable stylet. The bending stiffness of the needle resembles...
متن کاملAn Autoclavable Steerable Cannula Manual Deployment Device: Design and Accuracy Analysis.
Accessing a specific, predefined location identified in medical images is a common interventional task for biopsies and drug or therapy delivery. While conventional surgical needles provide little steerability, concentric tube continuum devices enable steering through curved trajectories. These devices are usually developed as robotic systems. However, manual actuation of concentric tube device...
متن کاملAngular Accuracy of Steerable Feature Detectors
The detection of landmarks or patterns is of interest for extracting features in biological images. Hence, algorithms for finding these keypoints have been extensively investigated in the literature, and their localization and detection properties are well known. In this paper, we study the complementary topic of local orientation estimation, which has not received similar attention. Simply sta...

15 صفحه اولA Testbed for Multi-lumen Steerable Needle Experiments
Steerable needles offer the potential to “turn corners” during insertion, thereby avoiding obstacles, reducing tip placement error, and enabling less-invasive access to challenging anatomical locations. In this paper we describe an experimental testbed designed to facilitate experiments with several popular steering mechanisms. One such mechanism makes use of asymmetric forces generated by a be...
