Title: Ready automated screening, diagnosis and classification technique for alzheimer's disease using magnetic resonance imaging signal from ventricular zone contour of brain

Abstract: The invention relates to a fully automated screening, diagnosis and classification technique for Alzheimer's disease using magnetic resonance imaging signals from the ventricular zone contour of the brain to get a fundamental index of brain deterioration comprising the steps: --obtaining a gray scale MRI image of the brain region; --applying a contour edge-detecting algorithm to the image; --employing a grid covering method for calculating a first order metric index of ventricular zone contour; --superimposing metric square grids of increasing edge length to the binary contour image and counting the metric grid squares; --plotting the logs of metric grid squares against the logs of edge lengths, wherein the gradient of the plot is the linear topological metric index.
