Abstract: With the development of high tesla MRI scanners，Diffusion Tensor MRI（DTI） has become an important clinic MRI examination modality.It researches on the problems of DTI image processing and visualization，and presents a DTI image computing and visualization system，named GraceDTI，developed in institute.Full pipeline through tensor estimation，DTI parameter image computing，tensor field visualization，fiber tracking and visualization procedures are implemented.This system can be used as an assistant tool for clinic DTI diagnosis and a platform for DTI image processing research.
