dc.description.abstract Advanced technologies in image processing and analysis are used extensively in x-ray image, working to improve X ray images, image data are used to gather details from location of the diseases or physiological processes. This study aims to enhance chest x-ray images using image processing technique where IDL program were used as platform to enhance the quality of the images, The sampling of this study consists of 50 patients who underwent chest x-ray image, the study was conducted and taking information from Modern Medical Center, data were collected in the period between December 2014 to May 2015. IDL program techniques such as histogram equalization, filtering an image with mean filter, are used on this study to analyzed and enhanced data (chest x-ray images). The study showed a significant difference between the original image and the image that processed using IDL techniques, in term of contrast by histogram equalization. The contrast was significantly increased and it was the mean before enhancement 0.78 and it became after enhancement 0.97, and the mean of the contrast before filter enhancement was 0.70 and it became after filter enhancement 0.90. Also there were significant reduction in noise and it was the mean in high intensity area before enhancement 5.18323 and it was reduced when were used the mean filter to 3.37592, and the mean of the noise was in low intensity area before enhancement 1.70899 and it was reduced to 1.22766.The mean of the signal in high intensity area before enhancement 7367 and it became 7382, and the mean of the signal in low intensity area before enhancement 1685 and it became 1630, and the mean of SNR in high intensity area before enhancement was 1421.31 and it became 2264.65,and the mean of SNR in low intensity area before enhancement was 536.195 and it became 511.648. en_US
