Relaxo LNI Introduction
The software exports a quantitative table of the segmented area (*.xlsx format), quantified maps, and drawn ROIs.

Relaxo LNI Requirement
-
MS Windows operating system
Relaxo LNI currently has the following functionalities:
-
Open raw DICOM multi-echoes T2 images
-
Whole-brain T2 estimation (exportable image in NIfTI)
-
Manual segmentation using free-hand or circular ROI tools (ROIs exportable in NIfTI)
-
Multiple visualization options: raw T2 (any echo), T2 with inverted contrast (make the T2 similar to a T1WI), quantified T2, and registered T1 (the tool performs the affine registration automatically)
-
You can draw your ROIs in several slices, creating a volume of interest (VOI). After drawing, you decide which ROI (slice) will be "captured" for the report, quantifications, and exportable NIfTI outputs.
-
You will always have the ROI intensities histogram available (considering the background image, whatever you choose). This provides information that enables ROI uniformity during the drawing procedure.
-
During the drawing procedure, the tool provides the T2 value, all ROI echoes values, and the relaxation plot in REAL-TIME!
