Abstract: A method for compensating respiratory motion in coronary fluoroscopic images includes finding a set of transformation parameters of a parametric motion model that maximize an objective function that is a weighted normalized cross correlation function of a reference image acquired at a first time that is warped by the parametric motion model and a first incoming image acquired at a second time subsequent to the first time. The weights are calculated as a ratio of a covariance of the gradients of the reference image and the gradients of the first incoming image with respect to a root of a product of a variance of the gradients of the reference image and the variance of the gradients of the first incoming image. The parametric motion model transforms the reference image to match the first incoming image.

Abstract: A method for three-dimensional reconstruction of a branched object from a rotational sequence of images of the branched object includes segmenting the branched object from each image of the sequence, extracting centerlines of the branched object, performing symbolic reconstruction via a stereo correspondence matching between the centerlines from different views of the sequence of images using a graph cut-based optimization, and creating a three-dimensional tomographic reconstruction of the branched object compensated for motion of the branched object between the images of the sequence.

Abstract: A system and method for automatically registering a three dimensional (3D) pre-operative image of an anatomical structure with intra-operative electrophysiological (EP) points of a 3D electro-anatomical (EA) image map of the anatomical structure is disclosed. The pre-operative image is displayed in a first supporting view. The intra-operative EA image map is displayed in a second supporting view. An alignment of the pre-operative image with the intra-operative map is performed by identifying at least one corresponding point on each image. The view of the pre-operative image is integrated with the EA map based on the alignment.

Abstract: A method for guiding stent deployment during an endovascular procedure includes providing a virtual stent model of a real stent that specifies a length, diameter, shape, and placement of the real stent. The method further includes projecting the virtual stent model onto a 2-dimensional (2D) DSA image of a target lesion, manipulating a stent deployment mechanism to navigate the stent to the target lesion while simultaneously acquiring real-time 2D fluoroscopic images of the stent navigation, and overlaying each fluoroscopic image on the 2D DSA image having the projected virtual stent model image, where the 2D fluoroscopic images are acquired from a C-arm mounted X-ray apparatus, and updating the projection of the virtual stent model onto the fluoroscopic images whenever a new fluoroscopic image is acquired or whenever the C-arm is moved, where the stent is aligned with the virtual stent model by aligning stent end markers with virtual end markers.
