Importing Lossless JPEG files

Some files (most noteable MR files from Embrace study) use Lossless JPEG compresion. The exact transfer syntax is:

JPEG Lossless, Non-hierarchical, 1st Order Prediction

The import of such files on some systems (newer MITK, most UNIX implementations) fails. A stackoverflow discussion member claims that:

Most toolkit on UNIX wont support JPEG Lossless originally because of some patent issue with the arithmetic codec.

Here there is more information on that.

The exact label of the JPEG Lossless standard is:

ITU-T T.81, ISO/IEC IS 10918-1

The standard is published here.
