Abstract

The invention discloses a coronary artery motion tracking method and device for a DSA image sequence. The method comprises the following steps: acquiring any two adjacent frames of images in a group of DSA image sequences; carrying out coronary artery structure enhancement, segmentation and refinement processing on the two frames of images, and respectively extracting coronary artery center lines;analyzing according to the local bifurcation structure characteristics and the curvature scale space image to obtain a corresponding relation of coronary arteries in the two frames of images; and onthe basis of the corresponding relationship, obtaining a coronary artery motion tracking result by utilizing Frescher distance-based consistency point matching. According to the method, the corresponding matched coronary artery is found in advance on the basis of the local features, the Frescher distance serves as the judgment basis of center line point matching, manual intervention is avoided, the topological consistency of the coronary artery structure in the registration process is guaranteed, and the method has low time complexity and high registration accuracy.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a coronary artery motion tracking method and device of a DSA image sequence. Background technique [0002] DSA technology is the gold standard for the diagnosis and treatment of cardiovascular diseases, and has an important medical status. However, due to the complexity of the coronary artery structure and the defects of the angiographic imaging process, there are certain limitations in clinical diagnosis and treatment. In order to assist doctors in visualizing and accurately locating the coronary artery position, and to achieve accurate and efficient diagnosis and treatment, it is necessary to accurately identify and match the coronary artery structure in the DSA image sequence to obtain the coronary artery movement. These are the important basis for subsequent image information fusion, and they are also technical difficulties that have always attracted much attention. ...
