Abstract
A 3D image processing system includes voxel adjustments based on radiodensity, filtering and segmentation, each of which may be selected, configured, and applied in response to controller-entered commands. Voxel adjustments based on radiodensity may include changes to grayscale values and color, e.g. to enhance selected tissues or to emphasize differences between tissues of similar radiodensity. Voxel adjustments based on radiodensity may include demarcation, and changes to voxel size, shape, and orientation. Filtering may include removing a portion of voxels of a selected radiodensity from a presented image. Segmentation may characterize voxels based on nearest neighbors, and grow features or fill gaps. Multiple images may be generated with different configuration settings and be combined into a composite image.
