Abstract/Summary We have proposed a new sampling scheme for Higher Angular Resolution Diffusion Imaging. The scheme is based on sampling the diffusion gradient directions periodically in a spiral over the unit sphere. Diffusion signal acquired with this scheme inherits the periodicity of the sampling, which brings post-processing opportunities for diffusion MRI data, such as denoising, compressed sensing and tractography. Here we have demonstrated its effect on signal-to-noise improvement.
