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.

  • added: PixelPaddingValue (0028,0120) is used to identify pixels to be excluded from the normal grayscale rendering. It is now supported when reading images
  • added (texture protocol): Local texture map calculation for GLCM indices
  • added (texture protocol): PARAMS_BinSize in result xls file
  • added (texture protocol): possibility to define bin size value only, without the number of grey level values in the graphical user interface

updated:

  • updated: display order of value voxel on top right of images is now in the same order than list of (layer) series
  • updated: improved circle3D and circle2D drawing performance
  • updated: crosshair coordinates in image space
  • updated: checking and modification of default bound values as a function of the imaging modality for automatic tuning of the display
  • updated: improved loading performance of RTStruct coordinates with multithreading calculation of each z slice
  • updated: loading (and also loading over network) now keeps images in data/temporary and not in /tmp in linux system
  • updated: enabling of ImageOrientationPatient(iop) and ImagePositionPatient(ipp) when loading Dicom(dcm) et Nifti(nii) images
  • updated: enabling of ImageOrientationPatient(iop) and ImagePositionPatient(ipp) when writing Nifti(nii) images
  • updated: memory is better used when launching the application (linux all available memory is used, windows 95% of available memory is used, mac os is set to 3.5Go of RAM for 4Go version, 7Go of RAM for 8Go version and 15Go of RAM for 16Go version)
  • updated: improvement of the selection of dropdown menus
  • updated: MIP nifti file fully saved (before this correction: only every other view was saved)

  • updated: discretization updated to agree with the image biomarker standardisation initiative (IBSI) description
  • updated: speed improvement when drawing circle2D and circle3D tools
  • updated (texture protocol): Z resampling disabled if 2D images are loaded
  • updated (texture protocol): different management of the zero values in NGLDM matrices. Only NGLDM_Contrast and NGLDM_Busyness are affected
  • updated (texture protocol): HISTO_kurtosis is shifted by a Fisher correction factor of -3 to have kurtosis equal to 0 for normal distributions
  • updated (texture protocol): values expressed in scientific format in excel file results
  • updated (texture protocol): discretization in agreement with the image biomarker standardisation initiative (IBSI) description
