摘要
PROBLEM TO BE SOLVED: To provide a method and apparatus for volume rendering based 3D image filtering and real-time cinematic volume rendering.;SOLUTION: A set of 2D projection image of 3D volume is generated using a cinematic volume rendering. A reconstructed 3D volume is generated from a set of the 2D projection image using an inverse linear volume metric ray tracing operator. The reconstructed 3D volume inherits noise suppression and structure enhancement from the projected image generated using the cinematic rendering, and is thus non-linearly filtered. A real- time volume rendering can be performed on the reconstructed 3D volume using a volumetric ray tracing, and each projected image of the reconstructed 3D volume approximates a cinematic rendered image of an original volume.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
