METHOD AND SYSTEM FOR 3D RECONSTRUCTION OF CORONARY ARTERY BASED ON VASCULAR BRANCH REGISTRATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20230128130 titled 'METHOD AND SYSTEM FOR 3D RECONSTRUCTION OF CORONARY ARTERY BASED ON VASCULAR BRANCH REGISTRATION
Simplified Explanation
The patent application describes a method and system for reconstructing a 3D model of a coronary artery using intravascular ultrasound (IVUS) images and coronary angiography (CAG) images. The method involves classifying different types of vessels in the IVUS image, segmenting the vessel walls, extracting a 3D centerline from the CAG image, locating vascular branches, and registering the segmented vessel walls to the 3D centerline for 3D reconstruction.
- Classifying bifurcated vessels and normal vessels in the IVUS image
- Segmenting the intima and adventitia of the bifurcated vessels and normal vessels separately
- Extracting a 3D centerline from the CAG image
- Locating vascular branches and automatically matching key points of the CAG image
- Registering the segmented vessel walls to the 3D centerline based on the key points of the CAG image
- Performing 3D reconstruction of the coronary artery
Potential applications of this technology:
- Assist doctors in diagnosing coronary artery diseases
- Aid in surgical planning for coronary artery interventions
- Improve the accuracy and speed of 3D reconstruction of coronary arteries
Problems solved by this technology:
- Difficulty in accurately reconstructing 3D models of coronary arteries using IVUS and CAG images
- Time-consuming manual matching of vascular branches in the images
- Lack of intuitive visualization for doctors to make judgments
Benefits of this technology:
- Provides a more intuitive visualization of coronary arteries for doctors
- Improves the speed and accuracy of 3D reconstruction
- Assists in the diagnosis and treatment planning of coronary artery diseases
Original Abstract Submitted
a method and system for 3d reconstruction of coronary artery based on vascular branch registration. the method includes: classifying bifurcated vessels and normal vessels of an intravascular ultrasound image and segmenting intima and adventitia of the bifurcated vessels and normal vessels separately; extracting a 3d centerline of a cag image; locating vascular branches and automatically matching key points of the cag image; and registering the intima and adventitia segmentation images to the 3d centerline of the cag image according to the key points of the cag image and performing 3d reconstruction of the coronary artery. the method uses automatic matching of vascular branches to fuse cag and ivus images and reconstruct them in 3d, which is more helpful for intuitive judgment of doctors on the premise of improving speed and accuracy, and is of great significance for auxiliary diagnosis of diseases.
