Artis-Zeego is an advanced interventional imaging system that can provide the three-dimensional (3-D) reconstruction of the coronary artery in real time. However, the mechanical accuracy will degenerate after long-time use. The inaccurate geometry will affect the spatial resolution of the 3-D reconstruction. We propose a calibration algorithm to tackle this problem. There are three steps of our algorithm. First, we propose a geometry estimation algorithm that is based on the classical helical ph...

Abstract Background 3D reconstruction of the coronary arteries can provide more information in the interventional surgery. Motion compensation is one kind of the 3D reconstruction method. Methods We propose a novel and complete 2D motion compensated reconstruction method. The main components include initial reconstruction, forward projection, registration and compensated reconstruction. We apply the mutual information (MI) and rigidity penalty (RP) as registration measure. The advanced adaptive ...

Coronary tree matching is applied to plan percutaneous vascular procedures. This work, which allows following each segment of non-isomorphic coronary trees over time, precedes the determination of the best 2D angiography view from C-arm acquisition system for angioplasty procedure. To match two 3D coronary trees which represent two successive cardiac phases, we adapted a reference inexact tree matching algorithm based on association graph and maximum clique. To improve the pair-wise matching per...

This special issue deals with the different main task which composes the CAD system, segmentation, image content description and classification to quantifying and identifying pathologies. It came out after the international conference on Image Processing Theory, Tools and Applications (IPTA 2014), which was conjointly co-sponsored by the IEEE French Section and EURASIP and held at Paris, on October 14–17, 2014. Some selected original research papers were encouraged by the IPTA 2014 TPC to extend...

Abstract The paper describes an inexact tree-matching algorithm to register non-isomorphic 3D coronary artery trees over time. This work is carried out in the frame of the determination of the optimal viewing angles on the C-arm acquisition system for coronary percutaneous procedure. The matching method is based on association graph and maximum clique. Different similarity measures are compared, which use tree characteristics and geometric features of vascular branches. In order to take into acc...

Tree matching algorithms have various applications in medical imaging for anatomical vessel system such as navigation in the tree structures, planning and treatment procedure or follow-up cardiac therapy. We consider that a dynamic sequence of 3D coronary trees is available from pre-segmented CT data or from reconstruction of the projections acquired from X-ray rotational angiography. We present an automatic graph-based method to find the best match between two non-isomorphic 3D coronary trees t...

: Kidney segmentation is an important step for computer-aided diagnosis or treatment in urology. In this paper, we present an automatic method based on multi-atlas image registration for kidney segmentation. The method mainly relies on a two-step framework to obtain coarse-to-fine segmentation results. In the first step, down-sampled patient image is registered with a set of low-resolution atlas images. A coarse kidney segmentation result is generated to locate the left and right kidneys. In the...
