Enhancement of Orthopantomogram Images by Using Image Possessing Technique

Abstract

The dental panoramic radiography is one of dental imaging that used to visualize the entirety of the maxilla and mandible jaws on one image. This study aims to enhance Orthopantogram images using image processing technique where IDL program were used .The sample of this study consisted of 95 images of Orthopantogram selected conveniently, the study was carried out in Elnasery Dental clinic during the period from DEC 2013 to April 2015. IDL program technique such as histogram equalization, filtering an image with mean filter is used on this study to analyzed and enhanced data. The results of this study showed a significant difference between the original image and the enhanced images in term of contrast through histogram equalization .The study showed the noise in low and high intensity before and after enhancement was 97.08 and 100.39 respectively, and in high was 64.31 and 59.09 and after using mean filter the result was 94.94 and 101.1 in low intensity and in high intensity areas was 63.9 and 59.57. The signal in low and high intensity before and after enhancement was 6581.2 and 6950.25 in low and in IX high was 4383.72 and 4383.72.
