Hands-Free System for Bronchoscopy Planning and Guidance


Bronchoscopy may be a commonly used minimally invasive procedure for lung-cancer staging. In normal follow, however, physicians differ greatly in their levels of performance. To address this concern, image-guided intervention (IGI) systems have been devised to boost procedure success. Current IGI bronchoscopy systems based on virtual bronchoscopic navigation (VBN), but, need involvement from the attending technician. This lessens physician management and hinders the overall acceptance of such systems. We tend to propose a hands-free VBN system for designing and guiding bronchoscopy. The system introduces 2 major contributions. Initial, it incorporates a replacement procedure-designing methodology that automatically computes airway navigation plans conforming to the physician's bronchoscopy training and manual dexterity. Second, it incorporates a guidance strategy for bronchoscope navigation that allows user-friendly system management via a foot switch, plus a unique position-verification mechanism. Phantom studies verified that the system allows swish operation below physician management, while conjointly enabling faster navigation than an existing technician-assisted VBN system. During a clinical human study, we tend to noted a ninety seven% bronchoscopy navigation success rate, per existing VBN systems, and a mean steering time per diagnostic website = fifty two s. This represents a guidance time usually nearly 3 min faster per diagnostic site than steering times reported for different technician-assisted VBN systems. Finally, an ergonomic study any asserts the system's acceptability to the physician and long-term potential.
