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).
