Abstract (en)

[origin: WO9840008A1] The present invention validates, conditions, and analyzes fluorescence spectral data for detecting the rejection of transplanted tissue. A spectral analysis dataset intended to represent the fluorescent response of animale tissue is obtained which indicates the luminous intensity of light collected at each of a range of wavelengths. In one embodiment of the invention, integrated intensities of the dataset are compared to maximum and for minimum intensity thresholds to determine validity. The validated dataset is then conditioned to render it suitable for analysis. The conditioned dataset is then analyzed by comparing extracted features to features of datasets from healthy tissue to detect possible tissue rejection.
