Title:
結合された強度の投影
Document Type and Number:
Japanese Patent JP5225999
Kind Code:
B2
Abstract:
The invention relates to a system (100) for rendering an image based on a volumetric image data set, the system comprising: a computation unit (110) for computing an initial pixel intensity of a pixel of the image, defined by a corresponding voxel intensity of a corresponding voxel comprised in the volumetric image data set; and an adjustment unit (120) for computing a final pixel intensity of the pixel, based on the initial pixel intensity and on a location of the corresponding voxel. Thus, the system of the invention enables new visualizations of volumetric image data sets. Advantageously, unlike a system using the VIP technique, which requires adjusting intensities of voxels comprised in the image data set, the system of the current invention is arranged to adjust intensities of pixels. This reduces the computational complexity of the rendering technique employed by the system relative to the computational complexity of the VIP technique.
