Robotic-Assisted Navigation for Lung Nodule Localization: A Non-Inferiority Study

Robot-assisted needle localization involves the use of a robotic system to assist with the percutaneous localization of pulmonary nodules under CT guidance. The robotic system provides real-time navigation and increased precision during needle placement, reducing the variability in positioning and improving the accuracy of localization. The system offers automatic adjustments to the needle's trajectory, minimizing the need for manual corrections, and potentially reducing the number of CT scans required. This method is designed to enhance the overall localization success rate and reduce complications associated with traditional manual techniques.

Manual needle localization involves the traditional technique of percutaneous localization of pulmonary nodules under CT guidance without the assistance of robotic systems. The procedure is performed by the physician manually guiding the needle based on real-time CT imaging. The physician adjusts the needle position based on visual cues from the CT scan, which may require multiple attempts for accurate localization.
