ABSTRACT
Four dimensional (4D) medical data are sequences of
volumetric images captured in time. These data sets are
typically very large in size and demand a great amount of
resources for storage and transmission. In this paper, we
present a lossless compression technique for 4D medical
images which is based on the H.264/AVC video coding
standard. Our lossless compression technique efficiently
exploits spatial and temporal redundancies between 2D
image slices and 3D images in 4D medical images and
eliminates any concerns regarding the effects of compression
on image quality for diagnostic purposes. Performance
evaluations have shown that the proposed compression
technique outperforms current 4D compression methods by
70%.
