Towards Lung Ultrasound Automation: Fully Autonomous Robotic Longitudinal and Transverse Scans Along Intercostal Spaces

Long Lei;Yingbai Hu;Zixing Jiang;Juzheng Miao;Xiao Luo;Yu Zhang;Qiong Wang;Shujun Wang;Zheng Li;Pheng-Ann Heng

IEEE Transactions on Medical Robotics and Bionics

Year: 2025 | Early Access Article |

Lung ultrasound scanning is essential for diagnosing lung diseases. The scan effectiveness critically depends on both longitudinal and transverse scans through intercostal spaces to reduce rib shadowing interference, as well as maintaining the probe perpendicular to pleura for pathological artifact generation. Achieving this level of scan quality often depends heavily on the experience of doctors....Show More
