摘要
目的:探讨改进的嵌入式零树小波编码算法压缩医学图像,以便应用于PACS。方法:应用嵌入式零树小波编码算法及本文提出的对其改进算法对CT医学图像压缩,并进行分析和比较。结果:改进的算法压缩医学图像取得了比原有EZW算法更好的压缩效果。结论:实验证明,本文改进的EZW算法优于嵌入式零树小波编码算法。
Objectiw: The method of Compressing the Medical Image Based on Embedded Zerotree Wavelet is presented in order .to apply in PACS. Methods:To apply the Embedded Zerotree Wavelet Encoding and improved EZW in this artical to compress medical image of CT and to provide a comprarative evaluation of the improved EZW with EZW. Results: The advantage in comoression efficiency of improved EZW over EZW was obtained. Conclusion: The algorithm of the improved EZW is ascendent than EZW.
