Neural networks enable autonomous navigation of catheters

When a patient has a stroke, every minute counts. Here, prompt action can prevent serious brain damage. If a clot is blocking a large blood vessel in the brain, surgeons can remove this occlusion by means of a catheter inserted in the patient's groin. However, this is a complicated procedure, requiring a lot of experience, and only a few specialists are capable of carrying it out. In new work, Fraunhofer researchers have been investigating whether artificial intelligence might be used to steer a catheter automatically and reliably to a blocked blood vessel.
