Claims21
1-32. (canceled)
A method for displaying contrast tomosynthesis reconstructed images of a breast of a patient, the method comprising:
- performing a tomosynthesis scan of the breast while the breast contains a contrast agent, the tomosynthesis scan comprising:
- moving an imaging x-ray source through a plurality of imaging positions along a source trajectory;
- obtaining a plurality of images corresponding to each of the plurality of imaging positions, the plurality of images comprising a first set of images each taken at a first x-ray dose and a second set of images each taken at a second x-ray dose, wherein the first x-ray dose and the second x-ray dose are different;
- based on the first set of images and the second set of images, deriving tomosynthesis reconstructed images representing respective slices of the breast;
- and
- displaying at least one of the tomosynthesis reconstructed images of the breast.

A method for performing a localization procedure in a breast of a patient, the method comprising:
- compressing the breast between a support plate and a compression paddle, wherein the breast is disposed between an x-ray source and an x-ray receptor;
- performing an imaging scan of the breast while the breast contains a contrast agent, the imaging scan comprising:
- moving an imaging x-ray source through a plurality of imaging positions along a source trajectory;
- and
- obtaining a plurality of images corresponding to each of the plurality of imaging positions, the plurality of images comprising a first set of images each taken at a first x-ray dose and a second set of images each taken at a second x-ray dose, wherein the first x-ray dose and the second x-ray dose are different;
- and
- based on the first set of images and the second set of images, deriving a set of tomosynthesis reconstructed images representing respective slices of the breast;
- localizing an area of interest in the breast based on at least one of the tomosynthesis reconstructed images;
- and
- positioning an insertable artificial element at the area of interest.

A method for performing a biopsy of a breast of a patient based on contrast-enhanced tomosynthesis reconstructed images, the method comprising:
- positioning a needle in the breast, based in part on three-dimensional coordinates of an area of interest;
- performing a pre-fire tomosynthesis scan of the breast, while the breast contains a contrast agent, the pre-fire tomosynthesis scan comprising:
- moving an imaging x-ray source through a plurality of imaging positions along a source trajectory;
- obtaining a plurality of pre-fire images corresponding to each of the plurality of imaging positions, the plurality of pre-fire images comprising a first set of images each taken at a first x-ray dose and a second set of images each taken at a second x-ray dose, wherein the first x-ray dose and the second x-ray dose are different;
- based on the first set of images and the second set of images, deriving pre-fire tomosynthesis reconstructed images representing respective slices of the breast;
- and
- firing the needle.
