NEAR-INFRARED SPECTRUM IMAGING SYSTEM FOR DIAGNOSIS OF DEPTH AND AREA OF BURN SKIN NECROSIS AND IMAGING METHOD

摘要

A kind of near infrared light spectrum imaging system diagnosed for burned skin necrotic depths and area, including optical spectrum imagers and computer control system. The optical spectrum imagers include light source (101), optical lens (102), filter (103), drive control device (105a, 105b, 104) and CCD cameras (106); The filter (103) uses wide range liquid crystal tunable optical filter (LCTF) or acousto-optic tunable filter (AOTF), they obtain the spectral signal of the 1100-250Onm wave bands of target area burned skin necrotic tissue. The computer control system is built-in with general module, data module, spectrum correction module, Spectral matching module, burn wound three-dimensional synthesis module. The optical spectrum imagers obtain the spectral image data of target area burned skin necrotic tissue, input the computer control system, by computer control system through image analysis processing, by the way that the standard spectrum reflectance curve for dead skin spectra database of burning in the corresponding spectral reflectivity curve of pixel each in spectrum picture and data module is carried out Spectral matching identification, the burn body and burn surface area of target area are obtained, and the 3-D image for synthesizing target area is shown.
