摘要:
A near-infrared spectrum imaging system for diagnosis of the depth and the area of burn skin necrosis comprises a spectrum imager and a computer controlled system. The spectrum imaging system comprises a light source (101), an optical lens (102), a filter (103), a driving controller (105a, 105b, 104), and a CCD camera (106). The filter (103) uses a wide-spectrum liquid crystal tunable filter (LCTF) or an acousto-optic tunable filter (AOTF) that obtain 1100-2500nm waveband spectral signals of burn skin necrosis tissue of a target region. A computer controlled system is internally provided with a universal module, a data module, a spectrum correction module, a spectrum matching module, and a burn wound three-dimensional synthesizing module. The spectrum imager obtains spectral image data of burn skin necrosis tissue of a target region and inputs the data into the computer controlled system, and the computer controlled system performs image analysis and processing of the data the depth and the area of burn of the target region can be obtained by means of spectral matching and recognition on a spectral reflectance curve corresponding to each image element in an optical image and a standard spectral reflectance curve in a burn skin necrosis spectral database in a data module, and the data is synthesized into a three-dimensional image for display.La présente invention concerne un système dimagerie à spectre proche infrarouge pour le diagnostic de la profondeur et la zone de nécrose cutanée après brûlure qui comprend un imageur spectral et un système commandé par ordinateur. Le système dimagerie spectrale comprend une source de lumière (101), une lentille optique (102), un filtre (103), un organe de commande dentraînement (105a, 105b, 104), et une caméra CCD (106). Le filtre (103) utilise un filtre accordable à cristaux liquides à large spectre (LCTF) ou un filtre acousto-optique accordable (AOTF) qui obtiennent des signaux spectraux dune bande donde de 1100 à 2500 nm dun
