Abstract: Systems and methods of stent enhancement in medical images includes obtaining a plurality of medical images of a vessel and a stent. A centerline of the vessel is obtained in medical images of the plurality of medical images. A deformation field across the medical images of the plurality of medical images is estimated based at least in part upon the obtained centerlines. The medical images of the plurality of medical images are registered to a common reference image. The images are temporally integrated to obtain an enhanced visual representation of the stent.

Abstract: A method for enhancing the visualization of a plurality of objects within an imaged subject. The method includes acquiring a plurality of images of the plurality of objects disposed in the imaged subject and supported by a plurality of guide wires; generating a complex deformation field based at least in part on a plurality of landmarks disposed in the plurality of images; and generating a composite image based at least in part on the complex deformation field. The complex deformation field models deformation induced on the plurality of objects by at least two or more guide wires of the plurality.
