DESCRIPTION

Raman spectroscopy is a technique used to determine molecular characteristics of materials through detecting Raman features of scattered light. STFC has invented a non-invasive method of examining bone quality and composition of other biological tissues using Raman spectroscopy. In particular, this invention processes scattering from surface and sub-surface tissue layers through a form of spatial gating. This method is called Spatially Offset Raman Spectroscopy (SORS).

 

KEY FEATURES

  • This is a non-invasive method of biological tissues which can be used for in vivo examinations of patients and living subjects
  • Incident probe beam from a laser is transmitted by optical fibres. A ring of optical fibres surrounding the transmission fibres collect scattered light which can be detected by CCD camera.
  • Uses Spatially Offset Raman Spectroscopy to determine biomedical characteristics of tissues at varying depths from the surface.

 

DOMAIN OF APPLICATIONS

  • Medical diagnosis e.g. degenerative skeletal diseases such as osteoporosis.
  • Longitudinal monitoring of musculoskeletal disease.
  • Non-invasive detection of blood characteristics through skin.
