| umls-concept:C1257736 | skos:definition | MSH: Projection of near-IR light (INFRARED RAYS), in the 700-1000 nm region, across an object in parallel beams to an array of sensitive photodetectors. This is repeated at various angles and a mathematical reconstruction provides three dimensional MEDICAL IMAGING of tissues. Based on the relative transparency of tissues to this spectra, it has been used to monitor local oxygenation, brain and joints.,CSP: imaging for in situ tissue microstructure optical biopsy; projection of near-infrared light across an object in parallel beams to an array of sensitive photodetectors; this is repeated at various angles and a mathematical reconstruction provides three dimensional medical imaging of tissues. | lld:umls |
