PET-FDG:  enabling the BrainMask\EdgeWave tool for brain extraction.

PET-FDG:   developing automatic function for "Target ROI" detection suitable for the Motion Correction.

Implementing "PET-FDG  motion correction"

Build 142A is released.

Further modified the "Linear Concentration" formula by disallowing the first 2 timepoints being considered a peak.

FireVoxel Build 142 is released.

ViewFilter dialog box is activated on F9.  This allows to easily activate dialog without accessing LayerControl dialog>ViewFilter functionality.

Re-designed ViewFilter dialog box so the color-value scale could be easier incorporated into the screenshot for the publication.

Dialog "Layer Operations": extended to 20 layers. Corresponding crashes are fixed.

FireVoxel Build 141 is released.

Dynamic Averaging function: corrected defect due to the conversion of the Real-volume to 32-bit representation.

Modified the "Linear concentration" formula, to compensate for initial "bright" timepoints.
In patient RE this resulted to Max concentration increasing from 0.005 to 0.03


Modified the RoiStats4D dialog, so that the linear concentration of ROI and fitted model could be displayed overlaid.

MainMenu>ROI>Skeleton:  added UI level function for ROI skeleton detection.  Simplistic algorithm works well in 2D case.  3D case would require new more complex algorithm.

PET brain "Ridge Segmentation" function:   finalized interface and functionality for 2D and 3D cases.  Simplistic skeletonization algorithm that works well in 2D, for some reason is not performing well in 3D and would require more time to integrate more precise 3D skeletonization.
Therefore, due to a limited time available,  "Process slices individually" option is always on in 3D case for the time being.

Initial test of FireVoxel "Detect Ridges" function on brain PET.

Implemented 2D ROI volume skeletonization function.

FireVoxel Build 140D is released.

Detected ridges function: corrected defect by enabling processing of 3D volumes.

Modified DlgRoiStats4D dialog when it is used after Parametric map modeling to display  RoiTAC vs. Fitted TAC.  "Show All" option is disabled in this situation.

FireVoxel Build 140C is released.
