A new method of signal processing and communications in model construction of finite element analysis

The medical modeling based on CT imaging had been widely used in the current finite element analysis (FEA) of biomechanical study. To find out a new rapid and efficient method of model construction became the key point of further study. In this article, we proposed a new modeling method which introduced the innovative employment of the SIEMENS SYNGO 3D software before further processing of MIMICS. With the automatic tissue margin determination and the three-dimensional cutting of SYNGO software, the model construction was much more rapid and accurate than the former manual discrimination and cutting method slice by slice. In this article, we expatiated on the process of associated application of these two kinds of software. Five models of lumbar spine in five different age groups were established by two methods, respectively. The time-consumption and accuracy were compared. The result showed similar model construction morphology, while the new method saved about 10 times as much time as traditional method. The new method was efficient, rapid and accurate. With the widely application of SIEMENS CT machine, the SYNGO 3D software becomes the major medical image processing instrument, which renders the feasibility for wide application for this new method of model construction.
