In this paper, the X-ray radiographs of the maxillary sinus in chronic sinusitis are analyzed and processed.
The Cumulative Distribution Function (CDF), calculated from the density histogram of the image, is introduced to evaluate the tonal content of the X-ray radiographs, because when X-ray radiographs is used in the diagnosis of chronic inflammation of the maxillary sinus, the most important data is provided by the density distributions.
The distance between the CDFs was defined as a criterion for determining the effectiveness of medical treatment. In the experimental results of twenty samples, this distance was successful for diagnosis of the stage of recovery in chronic sinusitis.
