The development of structural interventional catheterization for acquired or congenital heart disease was made possible through concomitant advances in catheterization techniques/tools and imaging techniques (fluoroscopy, ultrasound, magnetic resonance imaging and computed tomography). Imaging should provide an accurate view of the lesions and the surrounding cardiac structures, as well as the medical devices and catheters used. Here, we address the subject of image fusion. The principle of image fusion is based on the superposition of several imaging techniques: real-time fluoroscopy and multislice imaging performed offline or ultrasound imaging performed simultaneously. The goals are to improve the overall visualization of the organ and the surrounding structures, and to help the interventional cardiologist to interpret fluoroscopy images.
结构性介入导管术的发展，得益于导管技术/工具和影像学技术（透视、超声、磁共振成像和计算机断层扫描）的同步进步。影像学应能准确显示病变及周围心脏结构，以及所用医疗器械和导管。本文讨论的是影像融合。影像融合的原理是将几种影像学技术叠加：实时透视和离线多层成像，或实时超声成像。其目的是提高器官和周围结构的整体可视性，并帮助介入心脏病学家解读透视图像。
