Method for automatic identification of cardiac segmented regions

Method (100) for identifying segmented regions (P1-P26) of a heart, the method being executed by a control unit (12) and comprising the steps of:

• acquiring (S09) a heart mesh (40), the heart mesh (40) being a 3D graphical representation of the heart, including a left ventricle (66), a right ventricle (68), a heart apex (56) and a heart base (50) of the heart;
• determining (S11) a heart base plane (52) corresponding to the heart base (50);
• determining (S15), based on the heart base (50) and the heart apex (56), a left ventricular axis (58) extending across the left ventricle (66), from the heart apex (56) to the heart base (50);
• using (S23) the heart base plane (52) and the left ventricular axis (58) to identify said segmented regions (P1-P26), the segmented regions (P1-P26) being indicative of the left ventricle (66) and the right ventricle (68), each segmented region (P1-P26) being a respective portion of the heart mesh (40) satisfying a respective first criterion about a distance range (D1-D4) from the heart base plane (52) and a respective second criterion about a circumferential angular range (A1-A26) about the left ventricular axis (58).
