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)

Any software and data on this page is provided for academic research purpose only. Any publication using this
data must cite this webpage (www.vision.ethz.ch/4dmri)
and the respective article.
The following zip files contain:
- the motion fields for different breathing cycles of different subjects. Point trajectories
for isotropic grids of 15mm and 5mm are provided in both plain text and binary
- a reconstructed MRI volume per subject at exhalation in Analyze (*.hdr/img), Dicom (*.dcm) and MATLAB (*.mat) format.
The file datasets.pdf contains details about the provided motionfields such as temporal
and spatial resolution, acquisition time, etc.
Download the MATLAB file
displayMotionField.m to display the motion fields on specified slices
of the respective volumes.
