A Hybrid Method for Endocardial Contour Extraction of Right Ventricle in 4-Slices from 3D Echocardiography Dataset

Algorithm 1

Shape-based contour detection.

(1) Input: Binary-Segmented Image, S

(2) Output: Maximum Distances,

(3) Let , be reference RVCCP.

(4) Let P1, P2, P3 and P4.       /* four parts of the RV cavity area */

(5) MD₁← Max(, , )      /* call function Max for each part to */

(6) MD₂← Max(, , )      /* determine the maximum distance */

(7) MD₃← Max(, , )       /* value of RV cavity diameters */

(8) MD₄← Max(, , )

where … have been previously computed by GDC algorithm in section 3.1.2.
