LIFEx reads DICOM images locally or over a network using a DICOM browser 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 has been added, changed or updated in this new release? Here is a list of the most significant additions, changes or updates in LIFEx v7.2.0: Main: - added: script DcmToNii named ScriptLoadingSavingOfSeries to convert DICOM files into Nifti files. - added: reading of the RT-Struct with the DICOM browser - added: saving of histogram data in .csv format - improved: DICOM network communication and DICOM browser have been completely rewritten - changed: the Apache Log4j Security Vulnerabilities are fixed (the library does not exist anymore) Main (Series): - changed: SUV is now not required for Nuclear Medicine images (removal of SUV conversion error warning) - added: SUV property form to change SUV calculation values - added: possible loading of more than one series (in nifti format) using a single "drag and drop" - changed: inverse order of eye-buttons of series in MIP frame to have the same order as all other frames - added: de-synchronization of the MIP colour palette versus 2D colour palettes - added: Warm Metal, Red, Green, Blue color map on series - added: decomposition of the RGB channels for the ultrasound modality (automatic loading of the R, G, B series in addition to the main series) - added: display of the colorPalette written in the filename (of nifti files) when loading series - added: tunable W/L on series - added: new setting of image interpolation methods (in common setting): NO_INTERPLATION, BSPLINE2, BSPLINE3, BSPLINE4, BSPLINE5 (only QUINTIC_LAGRANGIAN method before) - changed: adding new series no longer changes the zoom and the current position of the series that is already loaded Main (ROI): fixed issue: affecting subtract ROI - added: uint8 format in nifti ROI saving - changed : naming of SaveAllInAll into Save-S (separate files), and SaveAllInOne into Save-M (merge Roi in one file) - fixed issue: display of sort box at start if sort is already activated (saved in session file) -
