摘要：
Complex anatomical information can be obtained from a 3D radiologic image by navigating through it in a manner similar to an endoscopic examination. Real-time computation of 'virtual' endoscopic views, however, is needed to permit interactive navigation. We present a fast volume-rendering method for computing such views. Our method, motivated by the temporal-coherence concept, performs dynamic volume rendering at interactive frame rates. Results demonstrate the method's efficiency and accuracy. Also, our method constitutes part of a complete virtual-endoscopic system we have devised. This system is illustrated for 3D pulmonary analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.
