The Research And Implementation Of Medical Image Enhancement Preprocessing Method

The living standard of people has been raised continuously. They focus more on their health. Illness is checked out early and cured in time, which is not only saving patients'lives and relieving patients'pain, but also lightening patients'burden. Medical images have the advantage of efficient, economic and noninvasive, so they are used widely in medical treatment activity. The medical image is an indispensable part of modern medicine. The quality of medical images directly related to the accuracy of doctors'diagnosis and treatment. However, sometimes medical images is not ideal,they can not show the information of lesions obviously. So it is very necessary to use appropriate image processing methods to process medical images.First, medical image enhancement methods'theories are studied in detail. In addition, in order to make the treatment effect better, we improve sharpen filter processing method. After that, this thesis emphatically introduces the medical image preprocessing system which is designed by the GUIDE of MATLAB. We not only briefly explain the whole design thought of the system and data management mechanism, but also detailedly introduce the achievement functions, implementation methods and important implement functions of each functions module. Then, we debug and run the medical image preprocessing system. At the last, we summarize and outlook the research, point out shortcoming and insufficient of the subject, and indicates the improvable direction.The quality of medical images after enhancement is improved. Each module of the medical image preprocessing system work fine, come to the anticipant design propose.
