Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] The early developmental zebrafish is transparent and can realize long-term optical imaging of brain blood vessels in vivo, which provides the possibility for image-based blood vessel research. The present invention uses the three-dimensional cerebrovascular image of the transgenic zebrafish Tg(flk1-GFP) taken by a laser confocal microscope as an example to describe the key steps in the system method of the present invention.

Abstract

The invention discloses a method and a system for processing and analyzing a blood vessel image, and provides a quantitative method for correlational researches such as researches about geometric and three-dimensional network characteristics and laws of a blood vessel network. According to the technical scheme, the method includes the steps of firstly, inputting a three-dimensional blood vessel image to the system, then obtaining relevant various characteristic parameters through isotropic interpolation, area-of-interest extraction, appropriate threshold-value blood vessel segmentation, connected region extraction, small-region elimination, morphological processing, blood vessel network central line extraction and three-dimensional image reconstruction and visualization operation, and sending and displaying a result to a user, and the characteristic parameters comprise blood vessel areas, blood vessel sizes, blood vessel lengths, the blood vessel segment number, blood vessel diameters, blood vessel density distribution, the loop blood vessel number in the blood vessel network, loop relevant segment ratios, weighted average series and the like.

Description

technical field [0001] The invention relates to a computer analysis technology of biological images, in particular to a method and system for blood vessel image processing and analysis. Background technique [0002] Biomedical research and clinical diagnosis involve extensive imaging of vascular network structures, but currently there is no good technical means for computer-aided feature quantitative analysis of vascular images. The brain is the organ with the most complex vascular structure among the many organs in the human body. The following uses the brain as an example for background description. [0003] The brain is a complex network of cells and is one of the most delicate organs. The research on the brain has become one of the most active frontier basic researches in the 21st century, but the research on the cerebrovascular has been neglected for a long time. At present, it has been shown that blood vessels participate in and play an important regulatory role in t...
