摘要

Biospeckle laser as an identifier of canceru00cdgenos tissues.The present invention relates to a numerical and graphical approach for the analysis of biospeckle laser and application to the identification of cancer tissues; the dynamic laser speckle allows the differentiation between tissues with different levels of activities, that is, when the Interference patterns show changes that may be related to the tissue examined.The cancer tissues have different rnetabolismo than healthy tissue, due to increased cell division or an increased resistance of cells to death. This difference in activity is detectable using the technique presented here.The traditional methods of Fujii and generalized differences associated with the spectral analysis allows the distinction between areas with greater or lesser activity and are interpreted together with the tool of moment of inertia which is applied in homogeneous areas of the image speckle dinu00e2m ICO in the field of frequency.The results are analyzed together to ensure greater accuracy in the interpretation, enabling to perform a marking in frequency for different types of cancer.The technique involves the use of a laser is stable and the lens expansive, so that all the region of interest is illuminated in the sample according to a standard angle and intensity, CCD camera and computer in order to achieve the acquisition and processing of the images.
