Displaying computer-aided detection information with associated breast tomosynthesis image information

A computer-implemented method for processing and displaying information associated with breast x-ray images, comprising:

• acquiring or receiving x-ray image data of a breast, wherein the acquired or received x-ray image data comprises a breast x-ray tomosynthesis volume computed from a plurality of x-ray tomosynthesis projection images, the breast x-ray tomosynthesis volume comprising a plurality of two-dimensional breast x-ray tomosynthesis reconstructed image slices corresponding to a respective plurality of slice depths in the breast volume;
• and
• computing a three-dimensional fibroglandular tissue density map of the breast based at least in part on information associated with the acquired or received x-ray image data of the breast, the three-dimensional fibroglandular tissue density map characterizing each location therein by a fibroglandular tissue density metric representative of an absolute proportion, by volume, of fibroglandular breast tissue in a local neighborhood of that location, wherein computing the three-dimensional fibroglandular tissue density map comprises processing at least two of the x-ray tomosynthesis projection images to compute, for each of the at least two processed x-ray tomosynthesis projection images, a respective two-dimensional volumetric breast density (VBD) map according to a predetermined VBD computation algorithm, the VBD map containing, for each location in the respective x-ray tomosynthesis projection image, information representative of an absolute cumulative height of the fibroglandular breast tissue and an absolute cumulative height of non-fibroglandular breast tissue in a correspondingly located column of breast tissue, wherein the three-dimensional fibroglandular tissue density map indicates a range of densities in the breast.
