AIM： With the rapid development of medical imaging and the deeply researches of surgical navigation as well as cerebral function, the image analysis and processing of digital imaging and communications in medicine （DICOM） increasingly becomes the hot point and emphasis of medical image processing. In this paper, an image post-processing system for magnetic resonance image （MRI） local enhancement based on hybrid programming between Visual C＋＋ （VC＋＋） and Matlab is proposed for the convenience of post-processing algorithm and image analysis. METHODS： The DICOM images from the Department of Radiology. Peking Union Medical College Hospital from January to October 2005 were collected to apply on the global enhancement based on expanding gray scale, and local contrast enhancement based on mathematical morphology. The hybrid program employed the method of Matlab engine in VC＋＋. RESULTS： The system provided a research platform for the algorithm of MRI local enhancement, and had the interface function of image format conversion between bitmap and DICOM. CONCLUSION： The processed MRI is of greater application worth in image analysis. The system affords an effective measurement for the research of local image contrast enhancement technology. The hybrid programming of VC and Matlab may be effective for the researches on the development of algorithm.
