目的利用计算机断层扫描（CT）和磁共振（MR）成像数据集的透视体绘制（PVR）模拟内窥镜下人体器官系统的视图，材料与方法从数据中重建螺旋CT和MR图像的透视视图，并根据其CT衰减或MR信号强度分配颜色和不透明度对组织进行分类。通过定义沿着样条路径的关键视图，通过解剖区域构建“飞行路径”。胸主动脉（n=3）、气管支气管树（n=4）、结肠（n=3）、鼻窦（n=1）、和肩关节（n=1），以显示图像沿着飞行路径。所有异常结果均在手术中确认。通过启用的组织密度，信号强度，和他们的三维空间relationship.CONCLUSIONPVR的全方位的评价是一种新的方式来呈现体积数据，并可能使非侵入性诊断内窥镜检查，并提供一种替代方法来分析体积成像数据的初步诊断。
PURPOSETo use perspective volume rendering (PVR) of computed tomographic (CT) and magnetic resonance (MR) imaging data sets to simulate endoscopic views of human organ systems.MATERIALS AND METHODSPerspective views of helical CT and MR images were reconstructed from the data, and tissues were classified by assigning color and opacity based on their CT attenuation or MR signal intensity. "Flight paths" were constructed through anatomic regions by defining key views along a spline path. Twelve movies of the thoracic aorta (n=3), tracheobronchial tree (n=4), colon (n=3), paranasal sinuses (n=1), and shoulder joint (n=1) were generated to display images along the flight path. All abnormal results were confirmed at surgery.RESULTSPVR fly-through enabled evaluation of the full range of tissue densities, signal intensities, and their three-dimensional spatial relationships.CONCLUSIONPVR is a novel way to present volumetric data and may enable noninvasive diagnostic endoscopy and provide an alternate method to analyze volumetric imaging data for primary diagnosis.
