1. A method for improving visibility of a plurality of objects within an imaged subject, the method comprising: operating a medical imaging system to: generate a plurality of images of a plurality of objects and landmarks supported by a plurality of guide wires disposed in an imaged subject, the plurality of landmarks comprising at least a first landmark and a second landmark; identify, in at least one image of the plurality of images, at least a first position of the first landmark and a first position of the second landmark; identify, in at least one other image of the plurality of images, at least a second position of the first landmark and a second position of the second landmark; generate at least a first deformation field based at least in part on the first and the second positions of the first landmark and a second deformation field based at least in part on the first and the second positions of the second landmark, the generated deformation fields modeling deformation induced on the plurality of objects by at least two guidewires of the plurality of guidewires; and generate a composite image based at least in part on the first and the second deformation fields resulting in improved visibility of the plurality of objects in the composite image relative to the visibility of said objects in the previously generated plurality of images; and displaying the composite image on a display screen with the improved visibility of the plurality of objects.
