Madison D. McCullough, Marie Muller, Thomas M. Egan, Gregory D. Buckner
TL;DR
This paper presents a new ultrasound probe design for better lung nodule removal during surgery by optimizing its maneuverability and imaging accuracy.
Contribution
The novel contribution is the use of MOGAs and DOE to optimize an actuated continuum probe for pulmonary nodule resection.
Findings
MOGAs and DOE were used to explore design tradeoffs for probe actuation.
The optimized probe enables intraoperative imaging and precise nodule mapping.
The design aims to improve margin delineation and patient outcomes in wedge resection.
Abstract
Pulmonary nodules are abnormal tissue masses in the lungs, typically less than 3.0 cm in diameter, commonly detected during imaging of the chest and lungs. While most pulmonary nodules are not cancerous, surgical resection may be required if growth is detected between scans. This resection is typically performed without the benefit of intraoperative imaging, making it difficult for surgeons to confidently provide appropriate margins. To enhance the efficacy of wedge resection, researchers have developed a modified ultrasound imaging approach that utilizes both multiple scattering (MS) and single scattering (SS) to enhance the accuracy of margin delineation. Clinical deployment of this novel ultrasound technology requires a highly maneuverable ultrasound probe, ideally one that could be deployed and actuated with minimal invasiveness. This study details the design optimization and…
