Parametric Cad Model Of The Lumbar Spine

7Tepe Parametric Lumbar Spine Model Tweaking parameters of associative CAD models offer interesting pathways for the application of artificial intelligence methods, such as optimization by genetic algorithms and neural networks. Construction of a robust lumbar verteral assembly requires a holistic design approach. The concept of using a layout-sketch as the core of a cad model is becoming more popular due to its top-down design philosophy. However, there remains local issues such as the contact properties at the transverse facet joints, which cannot be taken care of alone by the top-down approach. Inverting the perspective to a bottom-up approach and observing some of the intricate geometrical features of for example the laminae leads to a model that can simply be represented by a relatively scarce number of parameters, yet capturing the physiological aspect of the organ in quite an accurate way. For those who are interested in what our 7Tepe Parametric Lumbar Spine Model version 0.1 currently looks like, just download the source in Parasolid format (x_t extension) and import it to your favorite CAD system. Currently, we have not shared our source CAD file belonging to proprietary software products, but we intend to do so in the near future. Designed by Ogulcan in proprietary solid modeling software.7Tepe参数化腰椎模型（7Tepe Parametric Lumbar Spine Model） 对关联式计算机辅助设计（CAD，Computer Aided Design）模型的参数进行调整，为人工智能方法的应用提供了颇具价值的路径，例如借助遗传算法与神经网络开展优化工作。 构建可靠的腰椎椎体组件需采用整体化设计思路。以布局草图作为计算机辅助设计模型核心的理念，因其自上而下的设计哲学正愈发流行。然而，该方法仍存在局部细节问题，例如横突关节面的接触特性，仅依靠自上而下的设计路径无法妥善解决。若转换视角采用自下而上的设计方法，并对椎板等复杂几何特征进行分析，可得到一个仅需相对少量参数即可表征的模型，却能相当精准地还原该解剖结构的生理特性。 若想了解我们的7Tepe参数化腰椎模型（7Tepe Parametric Lumbar Spine Model）0.1版本当前的形态，只需下载Parasolid格式（扩展名为.x_t）的源文件并导入至您常用的计算机辅助设计系统即可。目前我们尚未分享隶属于专有软件产品的计算机辅助设计源文件，但计划在未来推出相关共享计划。 本模型由Ogulcan使用专有实体建模软件设计完成。
