ABSTRACT

CT Angiography (CTA)-X-ray image fusion technology has seen significant advancements in recent years, offering a more precise and efficient imaging solution for endovascular interventions in vascular diseases. By integrating preoperative CTA images with intraoperative X-ray fluoroscopy, this technology enables dynamic visualization of vascular structures and interventional devices, allowing clinicians to perform complex procedures with greater accuracy. Compared with conventional imaging techniques, CTA-X-ray image fusion reduces reliance on contrast agents, minimizes radiation exposure, and shortens operative duration. This paper systematically introduces the definition, principles, and procedural workflow of this technology, outlining its key technical developments and clinical applications. The ability to provide real-time guidance for interventional procedures enhances the accuracy of device deployment, particularly in complex vascular anatomies. Furthermore, its application has expanded across various vascular interventions, demonstrating significant potential in improving surgical outcomes. As the technology continues to evolve, its role in endovascular therapy is expected to become increasingly prominent, contributing to more precise and safer interventional strategies.
