目的将符合医学数字成像和传输(DICOM)标准的多帧医学图像转换成常用的流媒体格式文件。方法解析DI-COM多帧医学图像结构,设计相关解析算法,将DICOM多帧图像中的像素数据写入流媒体文件中。结果成功实现将DICOM多帧图像转换为AVI和WMV两种流媒体格式。转换后发现AVI格式影像清晰,体积与DICOM文件几乎等同;WMV格式是有损压缩格式,体积极小,可以节省大量存储空间。结论格式转换后非常适合网上播放和传输,因此对初步的远程医疗与疾病的及时诊断具有非常重要的意义。
Objective To implement converting Multi-frame image conformed to digital imaging and communication in medicine(DICOM) to common streaming media format.Methods By parsing DICOM Multi-frame image structure and designing relevant parsing algorithm,pixel data in DICOM multi-frame image were written into streaming media file.Results It was implemented that converting DICOM multi-frame medical image to two kinds of streaming media format:AVI and WMV.It was found that the image of AVI format was clear,and the volume size was almost equivalent with DICOM files;while WMV format was lossy compression,and its volume size was minimal.Conclusion The result showed that it could save lots of storage space and be fit for broadcasting and transmitting online,so it has important significance for preliminary telemedicine and timely diagnosis.
