ABSTRACT Aims: The objective of this research is to extract the aorta and to measure its diameter for preoperative planning of heart surgeries such as Endo Vascular Aortic Repair (EVAR) or Aortic Valvular Replacement (AVR). Study Design: Experimental Study. Methodology: In order to extract the aorta correctly, the spine is removed first. Then, the diameter of the aorta is measured by considering the curvature of the aorta, especially the aortic arch. The novelty of the proposed method is as follows. Results: The spine has been extracted and removed correctly and also the aorta has been extracted with the proposed method even if there is an aneurysm in the aorta. In addition, the diameter measured automatically is almost the same as that measured manually. Conclusion: It has become possible to extract the aorta even if the spine overlaps with the aorta. In addition, the measured diameter of the aorta ranges from 20 to 30 [mm], which is almost the same as the average of normal persons’ aorta. However, some parts of the heart were extracted as the aorta, and the diameter of the aortic arch was not correct. These are the issues for future works.
