Abstract: A method for providing tomosynthesis 3-D volume image data, executed at least in part on a computer, acquires a number of radiographic projection images of a subject over a range of angles. Reconstructed volume image data is generated from the acquired projection images. A number of regions of interest are defined within the reconstructed volume image data, wherein each region of interest has a number of image voxels. Image voxel data values are conditioned within at least one of the regions of interest to enhance contrast within the at least one region of interest. The conditioned image voxel data values are adjusted within the at least one of the regions of interest according to interpolation with two or more neighboring regions of interest. An image slice having at least a plurality of the adjusted image voxel data values is displayed.
