Here are 14 example volumes of one breathing cycle example4DMRI.zip.
The temporal resolution of the volumes is 362 ms.
Each volume consists of 256 x 256 x 25 voxels of the size 1.37mm x 1.37 mm x 4 mm.

Have a look at these avis, which show the animated volumes at different slices and as a Maximum Intensity Projection. Note, that the motion of the gall bladder and the intestines is arbitrary, because the slice selection (sorting) was based on the state of the liver.

slice A (avi)   slice B (avi)   slice C (avi)   MIP (avi)
