dcmqi: Converters between research formats and DICOM

Converters and library to support the use of DICOM for storing medical imaging analysis results


dcmqi (DICOM for Quantitative Imaging) is a free, open source library that implements conversion between commonly used imaging research formats and the standard DICOM representation. dcmqi can be used to create DICOM objects for storing voxelized image segmentations, parametric maps, and segmentation-based measurements. dcmqi uses DCMTK classess and libraries that support the individual objects, and uses ITK to support research formats.


Installation: We provide binary packages of dcmqi for Windows, macOS and Linux. We also provide a Docker image of the library. dcmqi can also be installed as an extension to 3D Slicer using 3D Slicer Extension manager. See installation instructions in the [user guide]](https://qiicr.gitbooks.io/dcmqi-guide) for details.
