Abstract The role of the medical image processing has gradually expanded as the development of technology and application of computer,and the needs of image processing from medical health has also increased. This research is all about developing a simple medical image processing system which can do more economic and popular support to the backward areas of health care. This system can do Level 1 operation like rotating and cropping on medical picture to achieve the basic purpose of image observation. Also it has Level 2 operation like histogram equalization, Wiener filtering, Gaussian filtering, equalization filtering processing for further de-noising and enhancement processing. At last, it has Level 3 operation like edge detection to make a more intuitive edge observation to facilitate the analysis of the image.This system completely features the basic requirements of medical image processing. This system uses Matlab, completely uses the advantages of Matlab in image processing medical images to complete operations on medical images.
