Abstract (en)

[origin: WO0006980A1] A multispectral topography system and method is provided whereby mammalian matter (18) is illuminated with a light source (43), and an image of a section (20) of the matter is transmitted to a multispectral imaging prism and mirror spectrograph (30) which substantially simultaneously, spectrally disperses the transmitted light. The spectral image is then acquired and prepared for further processing. The processor (37), typically resident in a computer system, processes the digital spectral data with a neural network to provide a diagnosis of the matter. The light source may be filtered light that is absorbed by specially prepared matter that reemits light (i.e. fluoresces). The matter could be pathological specimens to be magnified and analyzed by a microscope (transmission or fluorescent), or, alternatively, in vivo (live), whereby the image is transmitted by another conventional image transmitter, such as an endoscope. The system is also capable of displaying the transmitted visual image as well as the spectral image in conjunction with the diagnostic output.
