Three-dimensional (3D) computer reconstruction is an ideal tool for evaluating the centralized pathology of mammalian spinal cord injury (SCI) where multiple anatomical features are embedded within each other. Here, we evaluate three different reconstruction algorithms to three-dimensionally visualize SCIs. We also show for the first time, that determination of the volume and surface area of pa...

This study investigates the potential of microscopic Magnetic Resonance Imaging to obtain information for 3D digital atlases of mouse development using fixed samples. Fixed samples allow direct comparison with already published atlases and provide a testing ground for future in vivo efforts. 3D MR images of mouse embryos (dpc 6.5-16) illustrate that the necessary contrast and level of detail is...

Iterative reconstruction algorithms produce accurate images without streak artifacts as in ®ltered backprojection. They allow improved incorporation of important corrections for image degrading effects, such as attenuation, scatter and depth-dependent resolution. Only some corrections, which are important for accurate reconstruction in positron emission tomography and single photon emission com...
