abstract= {7 2D ultrasound sequences of the liver of healthy volunteers were acquired during free breathing over a period of 5-10 min. 

This is a converted version of the usliverseq dataset into mp4 files encoded with H.264 to reduce size and make the files easier to read.

The conversion commands used are:
```
$vlc volunteer06.avi --video-filter=scene --scene-prefix=movie --scene-ratio=1 --scene-path=volunteer06 --no-skip-frames

$ffmpeg -r 17 -i volunteer06/movie%05d.png volunteer06.mp4

$ffmpeg -r 25 -start_number 580 -i volunteer01/Image_120910_102034_%05d.bmp volunteer01.mp4
```

### Data notes:
