At the time when most of image data in hospitals are stored in digital form using picture archiving and communication systems (PACS), telemedicine goes through its boom, and demand for data storage and bandwidth requirements increases, lossy compression techniques become necessity. This review article summarizes different methods for quality measurement of image compression in radiology. After brief compression techniques description, technical and medical measurements (including Receiver Operating Characteristic Curves) of image compression are described. Employing of these methods in practice and their results are shown on sample studies. The article concludes with basic recommendations for experimental protocols when performing quality measurement of medical images.
当医院中的大多数图像数据使用图像存档与通信系统（PACS）以数字形式存储时，远程医疗迎来了繁荣发展，对数据存储和带宽的需求增加，有损压缩技术成为必然。这篇综述文章总结了放射学中图像压缩质量测量的不同方法。在简要描述压缩技术之后，介绍了图像压缩的技术和医学测量方法（包括接收者操作特征曲线）。这些方法在实际中的应用及其结果在样本研究中展示。文章最后给出了进行医学图像质量测量时实验方案的基本建议。
