Tapping the Terahertz: Capturing Clues in Tissue Hydration
Terahertz imaging has long been used in manufacturing applications, such as materials and pharmaceutical quality inspection, or in illicit drug and explosives detection. Due to its low photon energy and ability to penetrate certain types of materials, terahertz imaging holds a great deal of promise for the identification of key biological indicators — particularly those inherent in the skin — in life sciences and medicine.

NIR Spectroscopy Provides a Chemical Perspective on the Composition of Teeth
While dentistry has become increasingly sophisticated, uncertainties still exist in the diagnosis and treatment of dental conditions that are left to the discretion of the practitioner. Part of the reason for this uncertainty is that the composition of teeth is not static. Assessing changes can be useful in guiding clinical interventions, and the use of spectroscopic tools, particularly those that operate in the near-infrared range of the spectrum, are showing promise in this pursuit.

Surgical Microscope Uses OCT to Define Precise Tumor Margins
A megahertz-speed optical coherence tomography instrument integrated with a neurosurgical microscope has demonstrated the ability to acquire high-quality, volumetric, cross-sectional brain scans in seconds. The images obtained by the system are immediately available for post-processing.
