Abstract
The method for generating a resultant image comprises: defining curved slices between a compression plate and a detector, each curved slice having a shape that follows a curvature of the compression plate and/or detector or that represents a transition between the curvatures; reconstructing slice images that lie on the curved slices; generating the resultant image as a slice stack of the slice images; and outputting the resultant image.
Claims20
A method for generating a resultant image based on a tomosynthesis image dataset of a breast, which has been fixed to a detector by a compression plate, wherein a contact surface of at least one of the compression plate or the detector facing the breast has a concave curvature, and wherein the method comprises:
- defining curved slices between the compression plate and the detector, each curved slice having a shape that follows a curvature of the at least one of the compression plate or the detector or that represents a transition between the curvature of the compression plate and the curvature of the detector;
- reconstructing slice images that lie on the curved slices;
- generating the resultant image as a slice stack of the slice images;
- and
- outputting the resultant image.
