2CXM model was implemented using the Simplex Optimization with Gridding
Initial setup contains ROI region (orange) and Arterrial Input Function (blue). It is displayed as concentration.
Fitting curves displayed as Concentration
Resulting fitting optimal parameters

BiCal on 4D images: implemented an option and the user interface for "Static\Dynamic" field option when in "Static field" we perform BiCal only once on the starting timepoint and then apply the resulting field to the rest of the timepoints.

Whole Lever ROI was segmented on VIBE and.
Then GRASP was registered to VIBE+ROI.
Note: BiCal non-uniformity correction on GRASP was critical.
GRASP case 01
GRASP case 02
Initial variant of fully automatic liver registration from VIBE abdominal MR.
This uses: BiCal, Edge Constrained Smooth, EdgeWave with Competitive Growth.
VIBE case 01
VIBE case 02

FireVoxel Build 251A is released.
Layer Control Dialog: changed the logic so if no Layers are disabled then the Active layer is deleted with the warning.
Layer Control Dialog - fixed arbitrary Active layer change when switching between 2 documents.

Implemented an initial upgrade to EdgeWave: EdgeWaveCG (with Competitive Growth option)
Below is comparison of current EdgeWave and EdgeWaveGC with identical parameters and seed.
conventional EdgeWave: (0.9/3/5mm/8mm)
EdgeWave CG (0.9,3,5mm,8mm)
