研究了针对于静态图像进行压缩编码的国际标准JPEG2000,将其在医学影像图像的压缩中实现,并将压缩结果进行了比较分析。通过研究发现,作为一种基于离散小波变换的静态图像压缩编码算法,JPEG2000具有很好的压缩比和信噪比,适合对医学图像进行无损压缩,为医院开展PACS和远程医疗提供了技术上的支持。

In this paper,directing at the static image compression international standard JPEG2000,its image compression will be achieved in medical imaging and the results of compression will be comparatively analysed.The study found that based on discrete wavelet transform to a static image compression algorithm,JPEG2000 has a good compression ratio and signal noise ratio,very suitable for lossless compression of medical images,PACS provides the technical support for hospitals and remote health care.
