Three-dimensional electrical impedance tomography
Article Abstract:
A three-dimensional electrical impedance tomography (EIT) system has been developed with improved imaging capabilities for clinical applications, such as lung or brain imaging and diagnostic screening. EIT provides non-invasive imaging of internal conductivity distribution of the human body. The system is superior to the existing medical imaging methods because it is safe, portable and cost effective. However, the spatial resolution of EIT is poor as compared to the magnetic resonance imaging and X-ray computed tomography.

Seismological evidence for three-dimensional melt migration beneath the East Pacific Rise
Article Abstract:
Tomographic images are presented, revealing the seismic structure and anisotropy of the upper mantle of the East Pacific Rise. The seismological evidence shows an anisotropy consistent with two-dimensional mantle flow, although the anomalous isotropic structure requires three dimensional melt distribution. The results show that the intervals at which crustal magma chambers are replenished are closely spaced, and that characteristics of scale from the melt transport process are inherited by the crustal systems.

How Neanderthal molar teeth grew
Article Abstract:
High-resolution microcomputed tomography has shown that the timing of molar crown and root completion in Neanderthals matches with those known for modern humans, but more complex enamel-dentine junction morphology and a late peak in root extension rate has set them apart. These data are the first on internal molar microstructure and they have placed key Neanderthal life history variables within those known for modern humans.
