Highlights

● Automated pleural line identification: A method was introduced to automatically identify pleural lines in lung ultrasound images, ensuring diagnosis speed and accuracy.

● High reliability: An average of 90.45% identification rate of pleural lines was achieved in a comprehensive experiment on 890 ultrasound videos, highlighting its broad applicability and reliability.

● Efficient integration: The algorithm's rapid processing (1.36 seconds for a 5-second video) makes it suitable for seamless integration into ultrasound instrument software, aiding clinicians in diagnosing conditions like pneumo-thorax more efficiently.

Highlights

● The outcomes derived from simulation and ex vivo experiments exhibit precise control over the range of radiofrequency ablation when employing boundary temperature control. 

● It was observed in this study that a single ablation procedure can achieve an ablation diameter of up to 30 mm. 

● The regular index and elliptic index of the radiofrequency ablation area tend to be a spherical shape, which holds potential benefits for the radiofrequency ablation surgeries.
