基于ITK和VTK的脊髓扩散张量成像实现

扩散张量成像是一种新的磁共振成像技术,比传统的扩散加权成像更能够准确地反映出水分子的扩散情况.在脊髓的扩散张量成像方面的研究成果并不多,且存在很大的发展空间.提出并实现了基于ITK和VTK的脊髓图像扩散张量成像系统,其中使用ITK实现图像三维配准和扩散张量及其旋转不变量的计算等功能,使用VTK辅助完成三维图像显示,为脊...

Implementation of spinal cord diffusion tensor imaging based on ITK and VTK

Diffusion tensor imaging is a new magnetic resonance imaging technique,which can reflect the diffusion of water molecular more accurately than diffusion weighted imaging.Now only a few research results have been published in spinal cord diffusion tensor imaging and there is still a huge development space for it.A diffusion tensor imaging system for spinal cord based on ITK and VTK is proposed,in which 3D image registration,diffusion tensor and its rotation invariant parameters calculation arevimplemented by ITK,and 3D image display is assisted by VTK.The system provides a platform for spinal cord diffusion tensor imaging research.Simulation results show that this platform can effectively realize the function of diffusion tensor imaging and display.
