Title: METHOD AND SYSTEM OF AUTOMATIC ANALYSIS OF DOPPLER ECHOCARDIOGRAPHY IMAGES
Abstract:
A computerized method and system of automatically analyzing a Doppler echocardiography (DE) image, the method comprising: obtaining one or more trained weight vectors each corresponding to a polygon type with a fixed number of vertices; obtaining a plurality of candidate polygons belonging to at least one polygon type; extracting a plurality of feature functions from the DE image for each candidate polygon, including vertex related feature functions and edge related feature functions; calculating a score for each candidate polygon using the extracted feature functions and a trained weight vector corresponding to the polygon type with the same number of vertices as the candidate polygon; and determining a candidate polygon with a highest calculated score to be a predicted polygon for the DE image, whereby the predicted polygon represents a pattern enclosed in the DE image.
