摘　　要：目的:根据临床调查,DICOM3.0医学图像文件格式的解析及解决其显示问题是医学图像处理的基础,对医学影像技术的研究有重要意义。方法:首先针对DICOM3.0标准,系统分析了DICOM医学图像文件格式,主要阐述了文件信息头和数据元素的格式,提出了在Windows平台下利用线性调窗实现DICOM图像的DIB位图显示。结果:利用线性调窗成功实现了CT、MR图像的显示,同时针对默认状态下显示效果欠佳,采用手动调窗改善显示效果。结论:实验证明,该方法能较好地实现DICOM医学图像的显示,满足一定的临床需求,同时也为后续工作奠定基础。Objective： According to clinical investigation, analysis on the storage format of DICOM3.0 medical images files and displaying them is the basis of medical image processing. It is very important for medical imaging technology. Methods： Firstly, with the DICOM standard, the format of the medical images is studied, mostly the format of the information header and data element.Then the DIB display of the DICOM images in Windows platform is put forward, using linear window-transformation. Results： It is successfully realized the display of CT、MR images. With the manual window-transformation, the displaying would be better. Conclusion： As the results show, the method studied in the paper can preferably realize the display of the DI- COM medical images, meeting certain clinical needs, and laying a foundation for the following study.
