Phantom validation demonstrates real-time continuous radial MRI navigation for robotic cardiovascular surgery, indicating a viable radiation-free guidance alternative.
Cardiovascular dilation surgery is usually performed with DSA navigation, and excessive radiation during imaging harms both the patient and the physician. Magnetic resonance imaging can avoid ionizing radiation, but its imaging efficiency severely limits the performance of real-time imaging. Therefore, we construct a complete real-time magnetic resonance navigation system through continuous radial scanning mode and corresponding reconstruction methods and formulate a group of scanning strategies. The characteristics of the special derivative catheter under magnetic resonance imaging were tested by combining the partner's magnetically compatible robotic equipment. And the results demonstrated the feasibility of this method.
