医学图像有损压缩技术研究进展

摘要

Medical imaging has been the important basis for the medical diagnosis and treatment. With the resolution of medical imaging devices, the data amount of acquired medical images increases consistently, which creates heavy burden for image storage and transmission and seriously restricts the following application of medical images. The manner of lossy compression can realize the high degree compression for medical images under the constraint of certain image quality, which has been the research focus both at home and abroad. In this paper, the research progress on lossy compression for medical images is summarized, and the basic methods of quality evaluation under the condition of lossy compression are described. Finally, the development trend of lossy compression for medical images is expected.%医学成像已经成为医学诊断与处理的重要依据。随着医学成像设备分辨率的不断提高，所获取的医学图像数据量也在持续增长，这给医学图像的存储与实时传输带来了巨大压力，并严重制约了其后续应用。有损压缩方式能够在满足一定图像质量的条件下，实现医学图像较大程度的压缩，目前已成为国内外研究的热点。本文对医学图像有损压缩技术研究进展进行总结，并介绍有损压缩条件下的质量评价方法，最后对医学图像有损压缩技术的发展趋势进行展望。
