摘　　要：通过对数字图像压缩算法的分析与研究,提出一种有损压缩与无损压缩相结合的方法,对感兴趣区域的医学图像进行无损压缩,其它部分图像进行有损压缩。并通过实验验证得到了较好压缩质量的医学图像,解决了医学图像对存储空间和传输速度的要求问题,节省了大量的医学图像的存储空间,提高了医学影像的传输速度。Base on the analysis and studying to the compressing algorithmic of digital image,a method combines loss Im-age Compression with lossless image compression is proposed.The ROI used lossless compression,while the other part used loss Compression.This method has obtain the medical image of good compression quality which has tested by experi-ment,and solve the problem that the need of memory space and transfer speed.Saving plenty of medical image s memory space,increasing the transfer speed.
