Using a data-driven analysis of diffusion MRI called connectivity based cortical parcellation, we were able to segment the human inferior parietal lobule into spatially contiguous regions that closely match the human cytoarchitectonic atlas. This supports the cortical field hypothesis in that connectivity profiles appear to define the same field boundaries as histo-logic features. Here we present...
Low-cost image processing systems which can provide convenient access to image processing and analysis techniques hold great potential as diagnostic and research tools in medical imaging. At the University of Washington, we have developed a PC-based medium performance image processing system for use as an experimental radiological workstation. The workstation uses a standard IBM PC/AT personal computer...
Three-dimensional finite element models can be used in analyzing bioelectric phenomena such as electrophysiology, electrocardiology, and electrical stimulation. Typically, these models are large and complex, making the solution process computationally intensive. We have compared different numerical methods used in solving realistic three-dimensional models. The Gauss-Seidel successive over-relaxation...
