Abstract

The present invention relates to a DICOM image blood flow analysis system. The DICOM image blood flow analysis system comprises: a DICOM file reading and playing module configured to open one or more than one DICOM files to display continuous multi-frame images; a morphology transformation module configured to perform preprocessing of the DICOM files; a blood vessel area extraction module configured to extract the main body of the blood vessel radiography based on a DBSCAN cluster algorithm and extract the fine marginal portion of the blood vessel radiography through multi-scale Gabor filtering; a blood vessel central axis extraction module configured to fuse the context information to perform blood vessel enhancement based on the extracted blood vessel area, extract a partial extreme point to act as a blood vessel central axis and remove partial spurious central axis and find out a communication component so as to complete the central axis extraction through a central axis tracking morphological method; and a calculation module configured to analyze each frame of radiography liquid expansion area and calculate the average diffusion speed and instantaneous diffusion speed of the radiography liquid. The DICOM image blood flow analysis system is able to analyze the contrast agent expansion speed in a blood vessel in real time.

Description

technical field [0001] The invention relates to the technical field of medical imaging information, in particular to a DICOM image blood flow analysis system. Background technique [0002] With the rapid development of medical imaging informatics, due to the different manufacturers of medical equipment, the storage formats and transmission methods of medical images related to various equipment vary widely, making medical images and related information in different systems and different applications. Exchange is severely hampered. For this reason, in order to standardize the exchange of medical images and related information, the DICOM standard has been formulated, which is specially used for the storage and transmission of medical images. At present, in the field of medical image research, it not only involves the processing and research of static medical images conforming to the DICOM standard, but also begins to pay attention to the dynamic research of DICOM standard imag...
