AI Technical Summary

Technical Problem

The existing coronary interventional navigation technology has problems with insufficient real-time and complex image registration when dealing with complex coronary lesions, and periodic cardiac movement leads to image artifacts, affecting the accuracy of guidewire guidance.

Method used

The navigation system based on ECG and DSA coronary artery pattern is adopted to trigger X-ray image acquisition in real time through ECG signals, and combined with dynamic coronary artery pattern technology, the guidewire position is updated in real time to reduce cardiac motion artifacts.

Benefits of technology

It improves the clarity and navigation accuracy of coronary artery images, reduces the frequency of X-ray exposure and contrast agents during surgery, reduces the risk of radiation and complexity of surgery, and is suitable for interventional treatment of complex coronary artery lesions.

Abstract

The invention discloses a coronary intervention operation navigation system based on electrocardiogram gating and a DSA coronary map, and belongs to the technical field of medical treatment. The system mainly comprises an electrocardiosignal acquisition module, an X-ray image acquisition module, a DCR processing module, a guide wire tracking module, a display module, an X-ray control module and a central processing unit. The electrocardiosignal acquisition module is connected and communicated with the X-ray control module through the central processing unit, the X-ray image acquisition module is connected with the DCR processing module, acquired real-time images are transmitted to the DCR processing module for dynamic path generation, the guide wire tracking module is connected with the DCR processing module, position data of a guide wire is updated in real time, and the guide wire tracking module is connected with the central processing unit. And superposing the image on the generated coronary artery path diagram. According to the coronary intervention operation navigation system based on the electrocardiogram gating and the DSA coronary route map, the effects of reducing image artifacts caused by periodic movement of the heart and improving the navigation precision and safety in the coronary intervention operation are achieved.
