The use of magnetic resonance (MR) images for needle-based interventions offers several advantages over other types of imaging modalities (e.g., high tissue contrast and no radiation). However, MR-guided interventions face challenges related to electromagnetic compatibility of medical devices and real-time tracking of surgical instruments. This work presents a flexible needle steering system that...
Robotically-actuated catheters are being employed in endovascular interventions for their improved maneuverability and steering precision over conventional catheters. Fluoroscopy is commonly used to guide such medical devices during interventions. Motivated by the limitations and hazards associated with fluoroscopy, this study investigates the use of ultrasound images as a viable alternative for the...
