Construction of Integrated Mechanical Simulation Model of Whole Body for Alive Human

We are aiming at the mechanical simulation intended for the human body. The targeted mechanical simulation is structural mechanics (bone and soft tissue), fluid dynamics (blood flow), and kinetic (movement of the body). It constructs the simulation model of the whole body that can unitedly do these analyses. Moreover, it includes shape and the mechanical property in this model for the human body to be alive. We took a picture of X-ray CT and MRI for the volunteer. It created the data of 1mm voxel based on information of which it took a picture by X-ray CT. It can identify the soft tissue from the data of MRI. However, it has the spatial resolution and the problem of the distortion of the space, and it cannot construct the model as it is. We matched information on Xray CT and MRI, and constructed the whole body model. In addition, it can request the Young’s modulus of the bone in the measurement of the mechanical property value according to the X-ray transmission rate. We developed the automated system by which it requested the shape of the whole body and the Young’s modulus of the bone from transmission factor of X-ray CT. We had developed system was able to create VCAD data of the whole body of the human body. VCAD system is an integrated system of CAD,CAM,CAE. In this human body model we can manufacture the structure analysis, the flow analysis, and the implant constructed.
