Generating contours of brain tumor images by using their optical density information and image correlation techniques

Abstract

In this study, image correlation techniques were applied on opticaldensity information to generate contour lines of a tumor area within abrain slice image. The tumor area was scanned as a digital image and itsintensity amplitudes were converted into optical density amplitudes. Theoriginal image and the reference image which were constructed by theoptical density amplitudes were correlated and the results weregraphically displayed against the spatial coordinate of the brain sliceimage. The peaks of the graphs showed the healthy and tumor tissuetransitions. Contour profiling of the tumor tissue was generated byjoining these peaks.
