An Analysis of Pre-Processing Steps Involved in Diffusion Tensor Imaging (DTI), Diffusion Kurtosis Imaging(DKI) and High Angular Resolution Diffusion Imaging(HARDI)

This paper presents an analysis of the pre-processing steps involved in Diffusion Tensor Imaging (DTI), Diffusion Kurtosis Imaging (DKI) and High Angular Resolution Diffusion Imaging (HARDI). The pre-processing steps are essential for obtaining reliable and accurate results from these imaging techniques. The paper reviews the pre-processing steps for each imaging technique, including motion correction, eddy current correction, bias field correction, and denoising. The paper also discusses the challenges associated with each pre-processing step and provides an overview of the available methods for each step. Finally, the paper provides a comparison of the pre-processing steps for each imaging technique and suggests potential improvements for future research.
