Abstract

The invention relates to a blood vessel reconstruction method and device based on a dynamic perfusion image, equipment and a medium. The method comprises the following steps: screening a first blood vessel voxel belonging to an input artery and a second blood vessel voxel belonging to an output vein from each blood vessel voxel of a dynamic perfusion image; respectively generating an artery input curve and a vein output curve based on the contrast agent concentration change curves of the first blood vessel voxels and the second blood vessel voxels; determining a starting time when the contrast agent begins to reach the input artery based on the artery input curve, and determining a deadline based on an intersection point of the artery input curve and the vein output curve, so as to determine an artery time interval; determining the average contrast agent concentration of each vascular voxel in the artery time interval to generate a concentration distribution three-dimensional diagram; segmenting the concentration distribution three-dimensional image to obtain a candidate blood vessel voxel segmentation image, and reconstructing a three-dimensional artery blood vessel image after removing blood vessel voxels of which the peak reaching time is outside the artery time interval from the candidate blood vessel voxel segmentation image. According to the scheme, limitation can be avoided.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method, device, device and medium for vessel reconstruction based on dynamic perfusion images. Background technique [0002] With the development of image processing technology, vascular reconstruction technology has emerged, which can reconstruct three-dimensional blood vessel images. The reconstruction of three-dimensional blood vessel images is of great significance to human beings, especially to the field of medical technology, and can provide good support for data analysis. [0003] The current three-dimensional vascular reconstruction technology is generally based on angiographic images (ie, CTA images), which is too limited. Because, in addition to angiography, dynamic perfusion images are also important in the current detection technology. Therefore, how to use dynamic perfusion images to achieve vascular reconstruction is of great significance, whic...
