Patent ID: 8233683

Claim:
A method for generating an image based on computed tomography data, the computed tomography data including at least first image data and second image data, the first image data including individual image data associated with each of a plurality of first image voxels, and the second image data including individual image data associated with each of a plurality of second image voxels, the first image data being obtained using X-rays having a first X-ray energy level, and the second image data being obtained using X-rays having a second energy level, the method comprising: generating a plurality of individual resultant image voxels by blending image data for each of the plurality of first image voxels with corresponding image data for each of the plurality of second image voxels using a non-linear blending function, the non-linear blending function being based on a non-linear blending parameter indicative of a non-linear blending ratio for blending the first image data and the second image data; and generating the image based on the plurality of individual resultant image voxels.
