There is a major effort in medical imaging to develop algorithms to extract information from DTI and HARDI, which provide detailed information on brain integrity and connectivity. As the images have recently advanced to provide extraordinarily high angular resolution and spatial detail, including an entire manifold of information at each point in the 3D images, there has been no readily availab...
Perhaps more than any other "-omics" endeavor, the accuracy and level of detail obtained from mapping the major connection pathways in the living human brain with diffusion MRI depend on the capabilities of the imaging technology used. The current tools are remarkable; allowing the formation of an "image" of the water diffusion probability distribution in regions of complex crossing fibers at e...
Compressed Sensing (CS) or Compressive Sampling is a recent technique to accurately reconstruct sparse signals from under sampled measurements acquired below the Shannon-Nyquist rate. In this article, we present a CS based method for accelerating the reconstruction of the Ensemble Average Propagator (EAP), also known as the Propagator in Diffusion MRI (dMRI), by significantly reducing the numbe...
