What does the navigator system add to interventional procedures in the hybrid room?
The usefulness of two-dimensional fixed projection fluoroscopic imaging in the characterization of soft tissues and complex cardiac anatomy is limited. Moreover, it is currently insufficient for cardiac structural interventionism. Including recent three-dimensional cardiac ultrasound imaging techniques is necessary to improve anatomical images and spatial resolution.
Fusion or hybrid imaging using two-dimensional fluoroscopy in combination with static or dynamic imaging obtained from cardiac computed tomography angiography (CCT), cardiac magnetic resonance (CMR), and transesophageal echocardiography (TEE) have been successfully used for structural cardiac interventions. A fusion image is the superimposition of images acquired from different modalities within the same spatial coordinate. This image mapping process is called co-registration or image registration.
