JPEG Lossless decompression



I'm currently working on my capstone project at school which is a
DICOM Viewer. I have the viewer to the point were I support all common
formats except compressed images, which is my next area of work. I'm
want to support DICOM images with transfer syntax
1.2.840.1008.1.2.4.70, JPEG lossless non-hierarchical first-order
prediction.

However, I have just hit a wall with this. I have not been able to
find very many resources online as to how I need to decompress the
pixel data, whether it be the algorithm or a library of some kind.

I should point out that while my capstone project is for school on
requirement is that an outside source (usually a business) requests
it. As such this viewer is going to be used internally at a local
business, which I'm not sure, but may cause some problems with
licensing on libraries. Any help you can provide me will be greatly
appreciated.

Also, I don't know if it makes a difference or not not but I am
creating this in C#.
