Reading JPEG Compressed DICOM Files

[Jim Ziegler]

Hello All:

Does anyone have source code for reading JPEG compressed images that they
would be willing to share. Specifically, I am looking for software that can
read the Lossless Huffman encoding. This is the default standard for DICOM
files. At present, I must go through a rather painful process of loading
the files into Osiris and saving them in an uncompressed DICOM format. This
is fine for the occasional file, but when I must convert 60+ images at a
time, it becomes very frustrating and time consuming. I frequently receive
DICOM files for analysis, and some of them are JPEG compressed. I have a
program that I wrote to convert a series of DICOM files into one AVS field
file. I would like to include source code for reading these compressed
files.

I have tried using "FreeImage" from SourceForge.net. It will read a variety
of compression formats, including numerous JPEG encodings, but the one that
it will not read is the Lossless Huffman. I am aware of a several available
libraries for reading DICOM files, but each one comes at a premium price.

Any help you can give would be appreciated.

Thanks,

Jim
