| 摘 要： | 探索基于小波变换对肺部CT图像进行无损雎缩的新方法.采用基于离散小波变换方法的JPEG2000标准对3019张肺部CT图像进行无损压缩,并针对压缩后图像效果进行统计分析.结果表明,该方法不但可以达到12.0的高压缩比,而且具有较高的图像尤损压缩质量,为临床CT医学影像的储存与诊断,提供了有益的技术与方法.

| Abstract: | This paper studies a new method of wavelet transform in the lossless compression of medical image.Based on it,experiment compresses 3019 lung sufferer CT images with JPEG 2000 standard.By statistic analyzing the feature of images,experimental result proves that this kind of compression method achieves the compression ration of 12.0 with high lossless compression quality.It can be used to clinic diagnoses of medical images. |
