Computer Vision News 20 Standard practice uses fluoroscopy and a C-arm to visualize the catheters in real time. However, Pietro would like to see ultrasound used more often, as it poses no risk of ionizing radiation. “That’s a challenge for the vision community,” he identifies. “Ultrasound is non-ionizing but difficult to understand from a cognitive perspective. I would love to see more progress in understanding ultrasound images.” Magnetic tentacles platform description. a Overview of magnetic tentacle delivery bronchoscope and actuation system comprised of two robotic arms, each controlling the pose of an external permanent magnet (EPM). b Magnetic tentacle deployment and laser delivery to a targeted tumor. c Illustration of the tentacle delivery system and sensing. d Schematic of the magnetic tentacle showing the integrated shape sensing Fiber Bragg Grating (FBG) and laser fiber. Cadaveric experiment navigation results. Fluoroscopic images showing the final navigation locations in three primary targets in the sub-segmental bronchi of the cadaveric specimen for the manual catheter (yellow filled circle) and magnetic tentacle (red filled circle) in the lateral view (left) and posterior-anterior view (right). Regions shown are a inferior lingular segment, b apicoposterior segment, and c lateral basal segment. Separate fluoroscopic images from independent navigation with the manual catheter and magnetic tentacle are presented as an overlay for comparison purposes. Robotics in Medicine Lab
