Recently, the potential applicability of Computational Fluid Dynamics (CFD) methods in image-based 3D blood flow simulations in both diagnosis and prognosis of Coronary Artery Disease (CAD) was verified in a number of clinical studies. Strong correlations were demonstrated between the invasively measured and computed FFR (fractional flow reserve) as well as between variations in the computed wall...
In patient-specific coronary blood flow modelling, the computational domain is defined as a 3D mesh of the major coronary arteries reconstructed from medical images. The blood flow itself is described through the flow equations that are defined over this computational domain and further solved by methods of computation fluid dynamics (CFD) in terms of pressure and velocity fields. One of the major...
Real-time imaging is required to guide minimally invasive catheter-based cardiac interventions. While transesophageal echocardiography allows for high-quality visualization of cardiac anatomy, X-ray fluoroscopy provides excellent visualization of devices. We have developed a novel image fusion system that allows real-time integration of 3-D echocardiography and the X-ray fluoroscopy. The system was...
