For conventional flow simulators, excellent calculation mesh was indispensable. To generate excellent mesh, sufficient knowledge for computational fluid dynamics (CFD) was essential. Furthermore, the result of CFD depends upon mesh. These should be probable reasons why flow simulators were not very widely used in medical field. CFD system, which is compatible with medicine, should be easy to operate and independent from mesh quality. We developed a new CFD system for blood flow. In our system, voxcel data from diagnositic modalities were used as simulation in stead of refined meshes which were generated with CFD knowledge. Voxcel models for simulations were directly build from layers of gray scale images from medical modalities. Our system had already applied for a few clinical cases. Detailed methods and results should be described.
