**************** LIFEx public version 6.30 *****************
What has been added, changed or updated in this new release?
Here is a list of the most notable additions, changes or updates in LIFEx v6.30:
-fixed issue: the display bug when translating an ROI
- fixed issue: "image position (patient) (IPP)" on nifti ROI file
- fixed issue: scale of ROI histogram
- fixed issue: time on MR dynamic images with "trigger time" DICOM field
- fixed issue (Labeling protocol): properties frame set to "Always On Top"
- fixed on display: The exposure expressed in mAs (and not in mA as before) in CT images
- fixed on display: The exposure in CT images is slice dependent (and not the same for all slices as before)
- added: byte format in tiff image
- added on display: peak kilo voltage output of the X-Ray generator used for CT images
- improved: quick access to Y units (intensity, ...) and X units (time) settings directly on images
- improved: color change of text overlay on image (green text corresponds to settings that can be changed, while orange text shows settings that cannot be modified)
- improved: series tools are redefined
- improved: title "Edit" and "Tool" of ROI tools are now changed into "Create" and "Edit"

**************** LIFEx public version 6.20 *****************
version 6.20 - Fri Jui 9 19pm CEST 2020
What's been added, changed or updated in this new release?
Here's a list of the most notable additions, changes or updates in LIFEx v6.20
- added: writing of DICOM-RTStruct is available to save ROI
- added: internal frames in application ; by default, all application frames are now gathered in a single frame. The separated frame format can still be set using the parameter settings menu
- added: Sag alone layout template
- added: Cor alone layout template
- added: Laplacian of Gaussian image filter supported
- added (Texture protocol): availability of Laplacian of Gaussian filter before calculation
- added (Texture protocol): availability of Laplacian of Gaussian filter in texture script
- added (MTV protocol): addition of new ZYX spacing of series in xls file result
- fixed issue (Texture protocol): "Sorry, but no ROI is defined. Please define an ROI and start again" in texture scripts
- improved: properties file is now in xml format to support Russian characters
- improved: selected time frame of timing series for MIP display is available (and not fixed only at time 0)
- improved: opening multi-modalities dicom (example:CT + RT-STRUCT + RT-DOSE) in the same directory automatically creates their corresponding DICOMDIR
- deleted: all vertical layout protocols

Introduction

Texture analysis is gaining considerable interest in medical imaging, in particular to identify parameters that might characterize tumor heterogeneity. We developed an easy-to-use freeware enabling calculation of a broad range of conventional, textural and shape indices from PET, MR, US and CT images.

The software is written in Java and does not rely on any commercial libraries. LIFEx is dedicated to researchers, radiologists, nuclear medicine physicians and oncologists that giving access to 42 histogram, textural and shape indices in addition to conventional indices and where users can change calculation options (e.g. resampling method and number of grey levels for textural analysis).
