Enhancement of nuclear medicine bones images using image processing technique

Abstract

Nuclear medicine imaging is an incontestable vital tool for diagnosis, it provide I o- invasive manner the internal structure of the body to detect eventually diseases or abnormalities. Unfortunately ,the presences of speckle noise in these images effect edges and fine details which limits the contrast resolution and make diagnostic more difficult. This study aims to enhancement of bone scintigraphy image by using image processing technique and have been using IDL program to enhance quality of image in order to evaluate contrast enhancement in different nuclear medicine bone image such as grey color ad to evaluate the usage of new non linear approach for contrast enhancement, the random sample consist of 30 bone image for patients whom underwent bone scintigraphy scan ,the study was conducted and taking information from nuclear medicine department in Fedail hospital in period between to .IDL program techniques such as median filter and histogram equalization ,are used on this study to analyzed and enhanced data (bone scan image) .this study showing significant different between the original image and the image that processed using IDL techniques ,in terms of contrast especially in histogram equalization. the signal, SNR and contrast calculations in both black and weight area using median filter and histogram equalization which having mean of white and black area; 1178, 34.56135, 2639.5, 51.3737, 0.372803, 10511.5, 102.525, 15055.5, 122.7and 0.150303 respectively.
