Coronary angioplasty is an X-ray guided intervention, which aims at recovering the diameter of coronary vessels when the accumulation of fat in the vessel wall reduced it. During this procedure, a guide-wire is inserted in the blood vessel located at the wrist or groin. This guide-wire brings into the pathologic vessel a balloon at the level...

.CTA angiography brings potentially useful information forguidance in an interventional procedure. It comes with the challenge ofregistering this 3D modality to the projection of the coronary arterieswhich are deforming with the cardiac motion. A tree-spline i.e. a treewith a spline attached to each edge and shared control points...

Fusing pre-operative CT angiography with per-operative angiographic and fluoroscopic images is considered by physicians as a potentially useful tool for improved guidance. We propose a 3D/2D temporal tracking of one coronary vessel, based on a spline deformation, using pairings with a controlled 2D stretching along the paired curves and a...

Fusing pre-operative CT angiography with per-operative an-giographic and fluoroscopic images is considered by physicians as a potentially useful tool for improved guidance. To be adopted, this tool requires the development of tracking methods adapted to the deformations of the arteries caused by the cardiac motion. Here, we propose a 3D/2D...

In this paper we address the problem of cells detection from mi-croscopy images. We construct a dictionary of candidate shapes obtained from previous segmentation maps and define an energy function to select the best candidates. The energy minimization is performed by an iterative graph cut algorithm. The proposed approach optimally combines...
