NIfTI 2 DICOM converter

Converts NIfTI files to either:

  • DICOM
  • DICOM SEG
  • DICOM PM
  • DICOM TR
  • DICOM RT Structure
  • DICOM RT Dose files

Inputs:

  • Images in nifti format (file.gz)
  • Reference DICOM file
  • Output format

Operation Mode:

  1. Download reference DICOM file
  2. For each output format run different configurations of - plastimatch convert - Some require to manually build the struct. - dcmqi
  3. Upload file

Supported conversion formats:

  • DICOM
  • DICOM RT Structure
  • DICOM RT Dose
  • DICOM Segmentation image (SEG) - This conversion performs an initial format identification and only converts to DICOM SEG the available segmentation images.
  • DICOM Parametric Map (PM) - Only converts the detected parametric maps to DICOM PM. Idenfitication is done by filename. The approach is not efficient, but there is no logic on the outputs of the different tools, thus it can not be done in a different way.
  • DICOM Tractography Results (TR) - However, not in conformance with the DICOM TR standard. Only supported for the OLD QFM, given that it needs the input from both: Tracts in NII and in TRK.

Other known conversion formats NOT supported as of May 2023:

  • DICOM RGB
  • DICOM Structured reporting of measurements (SR)

Tool: bts_nifti2dicom

Limitations: 

  • In order to be able to use the dcmqi converter to DICOM SEG and DICOM PM, the reference DICOM files need to be validated by https://www.dclunie.com/dicom3tools/dciodvfy.html 
  • DICOM SEG, DICOM PM, and DICOM TR conversions are only applied to the files identified as such.
