Résumé
Developing the Chinese herbal medicine industry of Gansu is the measure to find new economy point of growth, construct characteristic industry and distinctive industry. Industry chains should be divided scientific, constructed completely and balanced. Industrial clusters about the formation model should be figured out.The excitation mechanism of enterprise-university-research institute cooperation should be constructed. Appropriate means of propaganda should be chosen. Talent training supporting system should be constructed. The supervision should be strengthened.
Résumé
<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>
