AI Technical Summary

Technical Problem

Current technologies for central angiography image segmentation and cardiac phase identification rely on manual operation, which is time-consuming, labor-intensive, and yields unstable results, making it difficult to meet the needs of rapid clinical diagnosis and precision medicine.

Method used

By marking feature points in the initial segmentation frame, ray rays are emitted based on polar coordinates to search for boundary points within a narrow band. The entire sequence of ventricular boundary contours is automatically extracted through region-driven segmentation. Combined with energy model optimization, the automatic identification of the entire sequence of ventricular cavity area and cardiac phase division are achieved.

Benefits of technology

It enables automated tracking of the ventricular boundary contours throughout the entire sequence and accurate identification of cardiac phases, shortening operation time, reducing the probability of human error, and improving diagnostic efficiency and reliability.

Abstract

The present disclosure provides a cardiac phase recognition method, device, equipment and storage medium, to realize multi-frame automatic segmentation and accurate cardiac phase recognition. The cardiac phase recognition method comprises: selecting an initial segmentation frame in the ventricular contrast sequence image data; performing ventricular boundary recognition based on the feature points marked in the initial segmentation frame to determine the ventricular boundary contour; for the image frame adjacent to the initial segmentation frame, taking the ventricular boundary contour of the initial segmentation frame as the starting contour, emitting a ray in a narrow band range to search for a boundary point in a polar coordinate manner, connecting the boundary points and performing region-driven segmentation to obtain the ventricular boundary contour; taking the image frame as a new initial segmentation frame, repeating the above steps for the next image frame to obtain the full sequence ventricular boundary contour; determining the ventricular cavity area sequence corresponding to the ventricular contrast sequence image data based on the full sequence ventricular boundary contour, and dividing the cardiac phase according to the ventricular cavity area sequence.
