  • Reading JPEG Compressed DICOM Files

    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

    I have tried using "FreeImage" from 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.
