We have developed the simulation system of hemodynamcs based on voxel model method for modeling and the new developed VOF-VOF corresponding to voxel model for the purpose of advance medical surgery. In image-based simulations, the pre-working such as the modelings of blood vessels and mesh generation require many cost, labour and time. To solve these problems, we adopted voxel mode which is constructed from medical image obtained from MRI, CT. Furthermore, the input system has been developed to efficiently input boundary conditions and calculation conditions. This system makes it possible for users to input boundary conditions and calculation conditions, confirming the location of a boundary to be set through the friendly interface.
We examined the precise of simulation system of hemodynamics in the case of the linear-tube. The numerical results were in agreement with theory solutions. As an example of hemodynamics simulation, we handled the blood flow in a cerebral artery with large scale problem. Our developed system could succeed in performing the simulation of hemodynamics.
Our developed system enables users to reduce the cost and time on total simulation process. Particularly, the cost and time of modeling and mesh generation are drastically decreased by adopting voxel model method and our developed new scheme. Input system of boundary conditions permits user to smoothly define the boundary conditions through the friendly interface, resulting in the reduction of the load of input boundary conditions.
