Integrated intravascular OCT (optical coherence tomography) image and DSA (digital subtraction angiography) integrating offline treatment system

Abstract

The invention provides an integrated intravascular OCT (optical coherence tomography) image and DSA (digital subtraction angiography) integrating offline treatment system, which comprises a data acquisition module, a DSA-image-based blood vessel segmentation and reconstruction module, an OCT-image-based blood vessel measurement module, a blood vessel three-dimensional imaging module, a DSA image and OCT image linkage module, an image reporting module and a transmission module. According to the system, a blood vessel is multidimensionally treated by combining a DSA image and an OCT image to further facilitate the accurate positioning of an interested blood vessel section; a blood vessel measurement result obtained by the DSA-image-based blood vessel segmentation and reconstruction module is compared with a blood vessel measurement result, obtained by the OCT-image-based blood vessel measurement module, on a cross section, so that the blood vessel treatment research accuracy of a doctor or a researcher after an operation is improved to facilitate the supply of a more perfect therapeutic schedule for an interventional operation in a similar case in the future.

Description

technical field [0001] The invention belongs to the field of medical equipment, and specifically refers to an integrated off-line processing system integrating intravascular optical coherence tomography (OCT) images and digital subtraction (DSA) images. Background technique [0002] Coronary angiography is an effective method for the diagnosis of coronary heart disease. Insert the catheter through the femoral artery, radial artery or other peripheral arteries, send it to the ascending aorta, then explore the left or right coronary artery orifice, inject contrast agent, and visualize the coronary arteries, which can clearly reveal the anatomical abnormalities of the coronary arteries The location, degree and scope of its obstructive lesions. Coronary angiography is currently an effective method for directly observing the shape of coronary arteries, and the medical profession calls it the "gold standard". Interventional treatment is required for areas with severe stenosis on...

Problems solved by technology

However, the vast majority of DSA images and OCT images only give the operator a certain guiding significance during the operation, and after the operation, these data are accumulated in the CD or server hard disk. When these images need to be called again, It is impossible to effectively combine DSA and OCT images, and when studying these cases, each doctor or researcher may obtain different data at the same vascular lesion, creating many obstacles for clinical research and case review
