Computed tomography with multiple detectors and the advancement of processors improved rendered images and three-dimensional reconstructions in clinical practice. Traditional axial slices form non-intuitive images because they are seen in only one plane. The three-dimensional reconstructions can show structures details and diseases with complex anatomy in different perspectives. Cinematic rendering is a newly three-dimensional reconstruction technique, already approved for clinical use, which can produce realistic images from traditional computed tomography data. The algorithm used is based on light trajectory methods and the global lighting model, which simulate thousands of images from all possible directions. Thus, the technique shapes the physical propagation of light and generates a realistic three-dimensional image with depth, shadows and more anatomic details. It is a multidimensional rendering acquired through complex lighting effects. The aim of this article was to show the advance of three-dimensional technology with the cinematic rendering in images exams of the thoracic wall.
多探测器计算机断层扫描以及处理器的进步改善了临床实践中的渲染图像和三维重建。传统的轴向切片形成的图像不直观,因为它们仅在一个平面上显示。三维重建可以从不同角度显示结构细节和具有复杂解剖结构的疾病。电影渲染是一种新的三维重建技术,已被批准用于临床,它可以从传统计算机断层扫描数据中生成逼真的图像。所使用的算法基于光轨迹方法和全局光照模型,该模型从所有可能的方向模拟数千张图像。因此,该技术塑造了光的物理传播,并生成具有深度、阴影和更多解剖细节的逼真三维图像。它是通过复杂光照效果获得的多维渲染。本文的目的是展示电影渲染三维技术在胸壁图像检查中的进展。
