Abstract

An imaging system (10) generates a layered reconstructed radiograph (LRR) (66) of a subject. The system (10) takes as input a three-dimensional (3D) or higher dimensional data set (68) of the object, e.g. data produced by an image scanner (12). At least one processor (32) is programmed to define a set of two-dimensional (2D) projection images and associated view windows (60, 62, 64) corresponding to a set of voxel value (tissue) types with corresponding voxel value specification (50); determine the contribution of each processed voxel along each of a plurality of rays (72) through the 3D data set (68) to one of the predetermined voxel value (tissue) types in accordance with each voxel value with respect to the voxel value selection specification (50); and concurrently generate a 2D projection image corresponding to each of the voxel value specifications and related image view windows (60, 62, 64) based on the processed voxel values satisfying the corresponding voxel value specification (50). Each image is colorized differently and corresponding pixels in the images are aligned. An LRR (66) is generated by layering the aligned, colorized images and displaying as a multi-channel color image, e.g. an RGB image.
