3D vessel reconstruction based on intra-operative intravascular ultrasound for robotic autonomous catheter navigation

Autor: Ainchil Cayuela, Maria Montserrat

In recent years, robotic technology has improved instrument navigation precision and accuracy, and helped decrease the complexity of minimally invasive surgery. Still, the inherent restricted access to the anatomy of the patients severely complicates
