Shape-sensitive ultrasound probe for coronary flow reserve ratio simulation

摘要

A medical system includes an IVUS medical device (102) configured for intravenous deployment, the IVUS device (102) comprising a ultrasound probe (302) for intravenous recording of the lumen and vessel geometry in which the IVUS device is deployed. A shape sensing system (104) is mounted on or in the IVUS device and comprises a single electromagnetic sensor at a tip of the IVUS device. This single electromagnetic sensor is configured to measure a position of the tip of the IVUS device during the intravenous deployment. A motion compensation algorithm (140) is configured to restore the 3D shape of the IVUS device from IVUS measurements and said position of the tip as the IVUS device is moved along the vessel.
