Abstract
A method for generating a synthetic two-dimensional mammogram with enhanced contrast for structures of interest includes acquiring a three-dimensional digital breast tomosynthesis volume having a plurality of voxels. A three-dimensional relevance map that encodes for the voxels the relevance of the underlying structure for a diagnosis is generated. A synthetic two-dimensional mammogram is calculated based on the three-dimensional digital breast tomosynthesis volume and the three-dimensional relevance map.

A method for generating a synthetic two-dimensional mammogram with enhanced contrast for structures of interest, the method comprising:
- acquiring, with a medical scanner, a three-dimensional digital breast tomosynthesis volume having a plurality of voxels;
- generating a three-dimensional relevance map that encodes for the plurality of voxels a relevance of an underlying structure for a diagnosis;
- and
- calculating a synthetic two-dimensional mammogram based on the three-dimensional digital breast tomosynthesis volume and the three-dimensional relevance map,
- wherein calculating the synthetic two-dimensional mammogram is based on ray-casting in the generated three-dimensional relevance map and the acquired three-dimensional digital breast tomosynthesis volume.
A mammographic device for generating a synthetic two-dimensional mammogram with enhanced contrast for structures of interest, the mammographic device comprising:
- an imaging device configured to acquire a three-dimensional digital breast tomosynthesis volume having a plurality of voxels;
- and
- one or more processors configured to:
- generate a three-dimensional relevance map that encodes for the plurality of voxels a relevance of an underlying structure for a diagnosis;
- and
- calculate a synthetic two-dimensional mammogram based on the three-dimensional digital breast tomosynthesis volume and the three-dimensional relevance map,
- wherein the calculation of the synthetic two-dimensional mammogram is based on ray-casting in the generated three-dimensional relevance map and the acquired three-dimensional digital breast tomosynthesis volume.
