Problems solved by technology

However, such a process is often time-consuming and laborious, especially when conducting longitudinal studies and large-scale screening
This largely limits the application of calcium scoring, which is difficult to promote as a routine examination in all cardiac CT scans

Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention and the accompanying drawings.

[0034] An automatic detection method for coronary artery calcified plaques based on cardiac CT images, the workflow is as follows figure 1 Shown: First, CUDA-accelerated maximum intensity projection (MIP) 3D reconstruction is performed on the cardiac CT image dataset read from the PACS server, and then the cardiac coordinate system is established to extract the volume of interest to reduce the density of other high-density regions such as the thoracic spine and ribs. interference, and then detect, classify and quantify the candidate calcified plaques in the volume of interest according to the designed calcified plaque features, and finally output the detection results.

[0035] The specific operation steps are as follows:

[0036] 1. CUDA Accelerated MIP Reconstru...

Abstract

The invention relates to an automatic detection method for coronary artery calcified plaques based on cardiac CT images, which belongs to the technical field of biomedical engineering. The technology is based on three-dimensional reconstruction of cardiac CT images, and uses a series of features to describe and distinguish coronary plaques from different angles. Arterial calcified plaques, followed by classification and quantification of coronary artery calcified plaque candidates in four stages, enabling automatic detection of calcified plaques. This technology can automatically and quickly detect and measure calcified plaques in a group of cardiac CT images and identify the coronary branches where they are located, which can effectively reduce the manual burden and errors caused by subjective factors, and improve the efficiency and accuracy of image reading , has important clinical significance, and obtains considerable social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of biomedical engineering, and in particular relates to an automatic detection method for coronary artery calcified plaques based on heart CT images. Background technique [0002] Cardiovascular diseases, including coronary heart disease, hypertension, congestive heart failure and congenital cardiovascular defects, are among the diseases with the highest mortality rates worldwide. The underlying cause of most heart attacks and sudden cardiac death is growing atherosclerotic plaques, which are considered vulnerable plaques. Calcified plaque in coronary arteries is a marker of the degree of atherosclerosis in that vessel and thus can be used as a predictive tool to predict the likelihood of coronary artery disease in both symptomatic and asymptomatic patients. [0003] Calcified coronary plaques may be located anywhere in the following main coronary arteries and their branches: left main (Left Main, LM), left...
