Problems solved by technology

[0004] For the first aspect, its function is mainly to enhance the display of vascular images, but it does not process the vascular structure
For the second aspect, it only simply extracts the blood vessel image, but does not analyze and model the shape, structure, characteristics of the blood vessel itself and the connection relationship between the blood vessel segments.

Abstract

The invention discloses a blood vessel tree generation and lesion recognition method, device and equipment and a readable storage medium. The method comprises the following steps: acquiring a medicalimage, wherein the medical image comprises a plurality of voxels; segmenting a plurality of blood vessel regions from the medical image, wherein the blood vessel regions comprise blood vessels and voxels having similar characteristics with the blood vessels; establishing an incidence matrix of the plurality of blood vessel areas according to the proximity relation among the plurality of blood vessel areas; respectively acquiring a blood vessel section and a blood vessel bifurcation point of each blood vessel area; according to the incidence matrix, the blood vessel sections, the blood vessel bifurcation points and the connection relations between the blood vessel sections and the blood vessel bifurcation points contained in the blood vessel areas are constructed into blood vessel graphs ofthe blood vessel areas; and establishing a plurality of corresponding blood vessel trees based on the plurality of connected sub-graphs in the blood vessel graph. According to the method, the form, the structure and the characteristics of the blood vessel image and the connection relationship between the blood vessels can be analyzed, and an accurate blood vessel tree is constructed.

Description

technical field [0001] The present invention relates to the technical field of medical image processing and application, in particular to a method for generating a vascular tree, a method for identifying a lesion, a method for studying and judging a lesion, a device, a device, and a readable storage medium. Background technique [0002] In the field of medical imaging, computer automatic extraction, modeling and analysis of vascular images, structures and shapes is a basic problem in realizing intelligent medical care. For example, in the field of CT (Computed Tomography, computerized tomography), effective information abstraction, extraction and calculation of vascular structures in output medical images can greatly improve the automatic identification rate of related lesions. [0003] At present, the research on vascular images in medical imaging mainly focuses on the following aspects: one is to use image processing methods to enhance the display of vascular structures in...
