3D visualization of magnetic resonance spectroscopy (MRS) data. The background anatomical image is a T1 MRI image containing a bright outline that roughly corresponds to the location of a tumor. The colored spheres are a sphere-based representation of concentrations of different metabolites, which are functional markers. How it works:
red spheres = choline
green spheres = creatine
blue spheres = glutamin
yellow spheres = n-acetylaspartate
sphere size corresponds to magnitude of the metabolite.
This image (and linked movie) shows a rotating 3D view of a vesicle that was semi-automatically segmented from a 3D TEM image reconstructed from a tilt series. A handful of seed points were placed in one slice of the image and the 3D vesicle was automatically extracted. The image also shows a very preliminary automatic segmentation of proteins extending through the vesicle wall; the extent of these proteins is currently clipped by an arbitrary global parameter setting.
The nanoManipulator system provides a virtual-reality interface to scanned-probe microscopes, including interactive 3D graphics and force-feedback (haptic) display and control. robinett-nano-movie-small shows a movie of the system in operation.
The UNC nanoManipulator (nM) application provided an intuitive interface to scanning-probe microscopes, enabling scientists from a variety of disciplines to examine and manipulate nanometer-scale structures. (Taylor II, Robinett et al. 1993) The nM displayed a 3D rendering of the data as it arrives in real time. Using haptic feedback controls, a scientist could feel the surface representation to enhance understanding of surface properties and to modify the surface directly. The nM greatly increased productivity by acting as a translator between the scientist and the instrument being controlled. (Finch, Chi et al. 1995)
