SYSTEMS AND METHODS FOR ULTRASOUND IMAGE-BASED USER GUIDANCE AND FEEDBACK DURING CARDIAC VEGETATION ASPIRATION

原文（中国語）

A device () for providing guidance during a procedure to remove tissue vegetation from an implant site using an aspiration catheter () in which aspiration is controlled by vacuum suction includes a Doppler ultrasound imaging device () configured to acquire ultrasound data of the implant site including Doppler ultrasound data of the implant site and imaging data of the implant site. An electronic processor () is programmed to identify a portion of the aspiration catheter in the imaging data of the implant site; measure fluid flow through the aspiration catheter as a function of time based on the Doppler ultrasound data corresponding to the identified portion of the aspiration catheter; and provide guidance for the aspiration based on the measured fluid flow through the aspiration catheter.
