From: A novel physics-based model for fast computation of blood flow in coronary arteries
A flowchart representing the steps involved in building a FAST framework. First, a luminal surface model and the centerline of the coronary artery are extracted from the CCTA for the 3D CFD simulation and FAST prediction of blood flow, respectively. Then, an ideal model is constructed to model the appropriate boundary condition. After the 3D CFD calculation is finished, a small part of the result is used for the optimization of correction factors. Next, the FAST method is established by applying the physics-based fast model to the centerline of the coronary artery, combining the boundary condition and corrected factors. Finally, the FAST framework (red frame) can be used to predict hemodynamics by inputting CCTA
