Empirical Analysis of Blood Plasma LIBS Images Using the Nonlinear Diffusion Method

In an attempt to develop a method of early epithelial ovarian cancer detection we apply a laser to blood samples. With laser induced breakdown spectroscopy, (LIBS), plasma state images of blood samples are prepared and analyzed. We apply an improved nonlinear diffusion filter in order to enhance relevant image edges and to remove noise and irrelevant texture. We hope to identify differences in the shapes of these images by which we can detect the earliest stages of ovarian cancer.
