Method for the Characterization and classification of kidney stones

The invention relates to a method for the characterisation and classification of kidney stones, comprising the following steps in which: (a) a plurality of samples of kidney stones are obtained and cut in order to observe the interior thereof, obtaining the flattest surface possible; (b) hyperspectral imaging (HSI) is used to obtain the spectra of the pre-cut kidney stones, with a plurality of regions of interest (ROI) being selected and the image being analysed using principal component analysis (PCA); (c) the main species are identified using factor analysis (FA); (d) atypical values are identified using principal component analysis (PCA); (e) the different types of kidney stones are analysed using principal component analysis (PCA); and (f) the artificial neural network (ANN) technique is applied to the data obtained from the principal component analysis (PCA) for the classification thereof.
