dcmqi (DICOM (dcm) for Quantitative Imaging (qi)) is a collection of libraries and command line tools with minimum dependencies to support standardized communication of quantitative image analysis research data using DICOM standard.

Specifically, dcmqi can help you with the conversion of the following data types to and from DICOM:

• voxel-based segmentations using DICOM Segmentation IOD
• parametric maps using DICOM Parametric map IOD
• image-based measurements using DICOM Structured Reporting (SR) template TID1500

As an introduction to the motivation, capabilities and advantages of using the DICOM standard, and the objects mentioned above, you might want to read this open access paper:

Fedorov A, Clunie D, Ulrich E, Bauer C, Wahle A, Brown B, Onken M, Riesmeier J, Pieper S, Kikinis R, Buatti J, Beichel RR. (2016) DICOM for quantitative imaging biomarker development: a standards based approach to sharing clinical data and structured PET/CT analysis results in head and neck cancer research. PeerJ 4:e2057 https://doi.org/10.7717/peerj.2057

dcmqi is developed and maintained by the NCI Imaging Data Commons project.

• install as easy as pip install dcmqi
• for alternative installation and usage instructions see dcmqi manual.
• check out our introductory tutorial
