LIFEx reads DICOM images locally or over a network using a DICOM browser, is compatible with Osirix and includes a powerful 3D reconstruction-based slice viewer. Volume of interest (VOI) can be either imported from previously created files or drawn and manipulated using LIFEx. Results are exported in Excel format files. LIFEx runs on Windows, MacOs and Linux. It is distributed with examples and includes a tutorial. User support is offered. Users can optionally contribute to the gathering of index values in different tissue types and different images as a public data bank of reference values is currently being built and integrated to the software for assisting the users with the interpretation of their results.

What's new in (feature release) LIFEx 3.74?


  • renaming TMTV protocol into MTV protocol
  • creation of a DICOMDIR when more than 2 directories are loaded simultaneously, if that file does not exist
  • adding of seriesDescription, studydescription and PatientBirthDate dicom tag of a DICOMDIR file
  • saving dicom (+anonymised) series in local disk
  • nifti ROI loading allows loading multi value ROI in the same ROI file


Major bug fixes:

  • sometimes, z shift of 1 voxel on ROI when loading RTSTRUCT file
  • fixed artifacts when there were more than 1 contour sequence by slice in RTSTRUCT files


Minor bug fixes:

  • now, release annoucement frame is not a modal frame
  • texture: improved management in script execution when binSize=0 and nbGreyLevel=0
  • texture: NGLDM_Busyness formula has now an absolute value at the denominator
  • loading of coronal DIXON MR images with more than one contrast in the same series
  • loading nifti-1 file when imagePositionPatient is not null
  • texture: inversion in output xls file (optional) between rows and columns of the grey-level zone length matrix (GLZLM)
  • improved tuning of the size of the menu windows as a function of the screen resolution and size
