The invention belongs to the field of medical image processing and application, and relates to a medical image follow-up processing analysis technology, in particular to an automatic cerebral aneurysm rupture risk analysis system based on cerebral hemodynamics, in particular to a three-dimensional hemodynamics automatic calculation process. A calculation program of the system comprises a model preprocessing module, a tracer particle module, a track statistics module, a skeleton extraction module, a griding sub-module and a fluid solving module. A main program of the calculation program is based on a python language, and a complex function module is packaged into a dynamic library based on C++ to be called by the main program. According to the process, a user only needs to provide a blood vessel stl model and designate the inlet and outlet surfaces of blood flow in the model and corresponding boundary conditions, and then the blood flow field quantity result can be automatically output. Blood flow simulation calculation can be completed through interaction with clinicians as little as possible, the aneurysm rupture risks are judged to be an extremely high risk group, a high risk group, a medium risk group and a low risk group, a physical simulation technology can be conveniently used for assisting an operation scheme, and clinical application is facilitated.
