The choice of medical imaging techniques, for the purpose of the present work aimed at studying the anatomy of the knee, derives from the increasing use of images in diagnostics, research and teaching, and the subsequent importance that these methods are gaining within the scientific community. Medical systems using virtual reality techniques also offer a good alternative to traditional methods, and are considered among the most important tools in the areas of research and teaching. In our work we have shown some possible uses of three-dimensional imaging for the study of the morphology of the normal human knee, and its clinical applications. We used the direct volume rendering technique, and created a data set of images and animations to allow us to visualize the single structures of the human knee in three dimensions. Direct volume rendering makes use of specific algorithms to transform conventional two-dimensional magnetic resonance imaging sets of slices into see-through volume data set images. It is a technique which does not require the construction of intermediate geometric representations, and has the advantage of allowing the visualization of a single image of the full data set, using semi-transparent mapping. Digital images of human structures, and in particular of the knee, offer important information about anatomical structures and their relationships, and are of great value in the planning of surgical procedures. On this basis we studied seven volunteers with an average age of 25 years, who underwent magnetic resonance imaging. After elaboration of the data through post-processing, we analysed the structure of the knee in detail. The aim of our investigation was the three-dimensional image, in order to comprehend better the interactions between anatomical structures. We believe that these results, applied to living subjects, widen the frontiers in the areas of teaching, diagnostics, therapy and scientific research.
出于目前旨在研究膝关节解剖结构的工作目的，医学成像技术的选择源于其在诊断、研究和教学中越来越广泛的应用，以及这些方法在科学界日益凸显的重要性。使用虚拟现实技术的医学系统也为传统方法提供了一个很好的替代方案，并且被认为是研究和教学领域最重要的工具之一。在我们的工作中，我们展示了三维成像在正常人体膝关节形态学研究及其临床应用方面的一些可能用途。我们使用了直接体绘制技术，并创建了图像和动画数据集，以便能够在三维空间中可视化人体膝关节的各个结构。直接体绘制利用特定算法将传统的二维磁共振成像切片集转换为可透视的体数据集图像。这是一种不需要构建中间几何表示的技术，其优点是能够使用半透明映射可视化完整数据集的单个图像。人体结构的数字图像，尤其是膝关节的数字图像，提供了有关解剖结构及其相互关系的重要信息，在手术程序规划中具有重要价值。在此基础上，我们研究了7名平均年龄为25岁的志愿者，他们接受了磁共振成像检查。通过后处理对数据进行处理后，我们详细分析了膝关节的结构。我们研究的目的是获得三维图像，以便更好地理解解剖结构之间的相互作用。我们相信，这些应用于活体受试者的结果拓宽了教学、诊断、治疗和科研领域的前沿。
