MR图像中的附加图信息(overlay)可以为磁共振波谱(MRS)提供指导, 同时能帮助医生定位病灶, 从而准确显示附加图信息, 对辅助医学影像诊断具有非常重要的意义.然而常用的一些DICOM浏览工具在显示DICOM医学图像时往往会丢失对于磁共振波谱研究有重要意义的附加信息.基于此种情况, 本文采用江苏省人民医院提供的磁共振波谱数据, 对像素的提取方法和附加信息进行仔细研究, 同时在DICOM图像上显示实验, 并在Eclipse开发环境中, 利用Java语言和开源包dcm4che-2.0.23进行DICOM显示程序dicomreader的开发.实验结果证明, 本文的Java程序dicomreader软件可以快速将DICOM转换显示为图像并精确显示出附加信息, 并且提取出来的附加信息可以用于研究人员定位脑肿瘤等病变组织、对脑组织进行三维重建、对MRI图像进行分割或是根据波谱信息进行临床诊断等相关研究.

Additional figure information in MR images is able to provide guidance for Magnetic Resonance Spectrum (MRS), helping located lesions, and it has certain clinical application significance. While several free Digital Imaging and Communication in Medicine(DICOM) Viewers are able to display DICOM image files and key information, however it still has some shortages in the applications to the area of scientific research. First at all, their major basic function is just to display images. In some extent, they could only give the assistance to the research of magnetic resonance data. And then they are unable to completely display some special kinds of DICOM images, such as Siemens/GE magnetic resonance imaging. The location information of MRI images would be often lost in it. Above all, a program named dicomreader that displays DICOM image properly is developed by using Java and the open source toolkit of dcm4che. The process for extracting overlay pixels and displaying additional information on the DICOM images is also proposed. Finally, the experimental results show that dicomreader is able to implement the conversion from DICOM to image quickly and display the additional information precisely. Meanwhile, the additional information extracted could be used by research personnel for locating the pathological change of organism, such as brain tumor, three-dimensional reconstruction of brain organism, the partition of MRI images, and clinic diagnosis based on the information of wave spectrum.
