本文基于高级视频编码方案（H.264/AVC）提供了一种有效的4-D医学图像的无损压缩方法。提出的方法通过递归应用多帧运动补偿来有效地减少所有四个维度的数据冗余。对包括功能磁共振在内的各种方式的真实4-D医学图像进行的性能评估显示，压缩效率的提高高达三倍，例如3D-JPEG2000等其他最先进的压缩方法。
This paper presents an efficient lossless compression method for 4-D medical images based on the advanced video coding scheme (H.264/AVC). The proposed method efficiently reduces data redundancies in all four dimensions by recursively applying multiframe motion compensation. Performance evaluations on real 4-D medical images of varying modalities including functional magnetic resonance show an improvement in compression efficiency of up to three times that of other state-of-the-art compression methods such as 3D-JPEG2000.
