Reconstruction of a digital three-dimensional model of fetal heart / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To explore the methods for constructing the digital three-dimensional model of fetal heart.</p><p><b>METHODS</b>Original two-dimensional CT image data sets were collected from 4 abortion fetuses with fetal malformations but not heart malformation or chromosomal abnormalities. The three-dimensional fetal heart model was reconstructed using Mimics14.0 software.</p><p><b>RESULTS</b>In the reconstructed three-dimensional fetal heart, the left atrium, left ventricle, right atrium, right ventricle, the ascending aorta, the main pulmonary and their branches, the superior cava and inferior vena cava were marked with different colors, and these structures could be displayed individually or with other structures. This model also allowed three-dimensional arbitrary scaling, shifting or rotation at any angle, and the diameter of the each vessel could be measured with the software.</p><p><b>CONCLUSION</b>The fetal heart model can be successfully reconstructed from the CT datasets using three-dimensional reconstruction software to facilitate clinical and anatomical teaching.</p>
