Because scattering has weak dependence on wavelength, the NIR window is primarily limited by the light absorption of blood at short wavelengths and water at long wavelengths. The technique using this window is called NIRS. Medical imaging techniques such as fluorescence image-guided surgery often make use of the NIR window to detect deep structures
Near-IR absorption spectrum of dichloromethane showing complicated overlapping overtones of mid IR absorption features.. Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). [1]
Diffuse correlation spectroscopy (DCS) is a type of medical imaging and optical technique that utilizes near-infrared light to directly and non-invasively measure tissue blood flow. [1] The imaging modality was created by David Boas and Arjun Yodh in 1995.
The end of the Dark Ages – first light and re-ionization: [3] Near-infrared spectroscopy (NIRS) at spectral resolutions around 100 and 1000 for studying the first light sources (stars, galaxies and active nuclei) that mark the beginning of the phase of re-ionization of the Universe that is believed to take place between redshifts 15–14 and ...
Diffuse optical imaging (DOI) is a method of imaging using near-infrared spectroscopy (NIRS) [1] or fluorescence-based methods. [2] When used to create 3D volumetric models of the imaged material DOI is referred to as diffuse optical tomography , whereas 2D imaging methods are classified as diffuse optical imaging .
Robert De Niro loves being a dad!. The Oscar winner, 81, opened up about mornings spent with his 20-month-old daughter Gia in an interview with The Sunday Times published on Saturday, Jan. 4. "I ...
Near-infrared spectroscopy, a spectroscopic method that uses the near-infrared region (from 780 nm to 2500 nm).
