1. A method for displaying a volume obtained by tomosynthesis, the method comprising: displaying a two-dimensional image of a slice or slab; receiving user input that defines, on the displayed two-dimensional image, a two-dimensional region of interest located in a plane of the image; and displaying, in the displayed two-dimensional image within the region of interest at least one of: images of the slices of a volume of interest associated with the two-dimensional region of interest; three-dimensional images of the volume of interest associated with the two-dimensional region of interest; and slabs obtained from the volume of interest associated with the two-dimensional region of interest.
