A command-line utility for decompressing DICOM files with compressed pixel data. Optionally, ff photometric interpretation is one of YBR_FULL, YBR_FULL_422, PALETTE COLOR pixel data will be transcoded to RBG.

pip install dicom-decompress

This will install the terminal command dicom-decompress in your environment.

Some transfer syntaxes need the c++ library GDCM installed. Install this by

conda install gdcm -c conda-forge

See here on how to install conda.

To decompress a single file run

dicom-decompress in.dcm out.dcm

where in.dcm is the file to decompress and out.dcm is the decompressed target file. To attempt transcoding for non monochrome or rgb images add the --transcode flag:

dicom-decompress --transcode in.dcm out.dcm

To decompress multiple files in-place run e.g.

find . -name "*.dcm" -exec echo {} \; -exec dicom-decompress --transcode {} {} \;
