摘要: We have previously described a new approach to planning treatments for cardiovascular disease, Simulation-Based Medical Planning, whereby physician utilizes computational tools construct and evaluate combined anatomic/physiologic model predict the outcome of alternative treatment plans an individual patient. Current systems Planning utilize finite element methods solve time-dependent, three-dimensional equations governing blood flow provide detailed data on distribution, pressure gradients locations recirculation, low wall shear stress high particle residence. However, these are computationally expensive often require hours time parallel computers. This level computation is necessary obtaining information about flow, but likely unnecessary mean rates losses. describe, herein, space-time method solving one-d...
