[Reconstruction and three-dimensional printing (3D) of the neurocranium of a dog from computed tomography used as a tool for anatomy veterinary teaching]

ABSTRACT The three-dimensional printer (3D) has been contributing to the learning of anatomy and applied areas of veterinary medicine using an interface that can enhance the knowledge of the anatomy of domestic species in a dynamic way. The present study aimed to use three-dimensional images generated by computed tomography (TC) to obtain digitized images and bone models of the dog skull using a three-dimensional printer. The 3D files were generated from images that were edited in Osirix Lite software. Parts of the bones and anatomical features of the skull were printed on 60% and 100% scales. The results allowed to generate digitalized images and three -dimensional impressions from the tomographies, and in this way a collection of images and printed models was created for studies of the anatomy of the canine species. In addition, the methodology clearly demonstrated the importance of using surgical planning in cases involving procedures involving bone structure impairment. Interactive material and 3D printing with high durability that could be made available for educational purposes has been produced.摘要 三维打印机（3D）一直以来均可通过可动态增强家养物种解剖学知识学习效果的交互界面，为解剖学与兽医学应用领域的学习提供助力。本研究旨在依托计算机断层扫描（TC）生成的三维图像，获取数字化图像并利用三维打印机制作犬颅骨骨模型。研究所用三维文件均由在Osirix Lite软件中编辑的图像生成。研究人员按60%与100%的缩放比例，打印了颅骨的部分骨块及解剖结构。实验结果成功从断层扫描图像中生成了数字化图像与三维实体模型，由此构建了一套可用于犬类解剖学研究的图像集与打印模型集。此外，该研究方法清晰论证了在涉及骨骼结构损伤的手术操作中应用手术规划的重要性。本研究制备了可用于教学用途的交互式材料与高耐用性3D打印制品。
