Fixed the crash on  ROI image only (without SI volume) when the RoiStats3D dialog (F3) is activated.

Color Dialog defects:  fixed the   "always 0 color" and "crash on the exit" defects by recompiling the FireVoxel.exe module with 8-byte alignment.

Replaced all numerical ("double float") fields handling within all of the 76 Dialog boxes in FireVoxel.

MFC dialog "double float" numerical field failure:  developed a workaround by replacing MFC function:  

           AFXAPI DDX_Text(CDataExchange* pDX, int nIDC, double& value)

with the custom function.  This custom function will be in place till the MFC dialog problem is fixed.

Completely removed the Intel\TBB library from FireVoxel.exe and all DLLs.  This was replaced with the Microsoft's native library <ppl.h>.  Dependency on the VC++ 2013 redistributable was removed from the FireVoxel.

All higher level DICOM processing function (incl.  Constructing DICOM tree, etc) - was moved out of the main FireVoxel.exe to the VolumeAnalyze. dll.  This is to improve the architecture by leaving only the User-Interface functionality in .exe while moving all the math and processing into the dll.
This architecture is also more suitable to working with the command line modules if this would be required.

Diagnosed a major MS VC++ defect regarding the numerical input fields in MFC dialog boxes.
Came up with the workaround for standalone applications - fixing FireVoxel would require linking the FireVoxel project (UI part) with the debug version of the MFC.

Windows native CColorDialog contain a defect in current release of VC++ 2015.
Encapsulated this dialog within a standard call to avoid crash.  Replace all 6 occurrences of this dialog within other dialogs.

Fixed the defect when after running the "Segment Whole Kidney with blanket", the Volume display interpolation would always reset to FALSE.

Implemented new model:  Sokoloff (Short formula) with 2 Input functions and Double Pass (with optional parameter fixing after the first pass).

FireVoxel Build 196 is released.

1. Fully compiled and linked all the FireVoxel libraries in 64-bit mode.
2. Upgraded development environment to VC++ 2015 (v 14)
3. CFileDialog  (Load\Save) started to cause crash under VC++ 2015. This happened when the initial Directory path was specified during initialization.  Fixed the crash by setting the VistaStyle=0. It is purely Microsoft's bug so the flag is just a workaround.
4. DCMTK 64-bit reengineering: supplied an external definition for HostID and removed the DCMTK for obtaining network hostID that was crashing in 64-bit Release mode.
5. FireVoxel-64 bit is completely cleared on all ABT subtests in Debug|Release modes.
6. Fixed the b-value loading problem on the "*.time" 10-timepoint dataset from MSKCC.
7. Multi-projection crosshair cursor - corrected redrawing when the User paints with the paintbrush. Before the crosshair would only partially redraw leaving numerous lines on the screen.

12. Implemented basic variant of Monte-carlo simulation for all Dynamic Models in FireVoxel.
13. Implemented a new menu "Dynamic Processing" in the MainFrame part of the processing (i.e. when no volume is required to be loading).
14. Implemented the functionality for F3\F4    Roi Stats  3D\4D:  when ROI is missing, function calculates stats for the ROI that covers the entire volume.
15. Dynamic Experiment framework: fixed defect in all models involving the Input Function(s).
16. Enabled that Concentration conversion parameters are remembered and then recalled between several calls to the corresponding dialog box.

In Menu items:

Enabled that Concentration conversion parameters are remembered and then recalled between several calls to the corresponding dialog box.

Dynamic Experiment framework: fixed defect in all models involving the Input Function(s).
When Concentration conversion other than "Signal" was specified, the converted signal was posted
over the original signal data.  So on the following runs, the model calculations were entirely wrong.

Implemented the functionality for F3\F4    Roi Stats  3D\4D:  when ROI is missing, function calculates stats for the ROI that covers the entire volume.

Implemented a new menu "Dynamic Processing" in the MainFrame part of the processing (i.e. when no volume is required to be loading).

Implemented basic variant of Monte-carlo simulation for all Dynamic Models in FireVoxel.

User starts with obtaining the required ROI and saving it to the file.

User create a 4D-volume from the specified TAC setting the level of noise (10% in this example). Then runs the chosen model over the 4D volume, where each voxel corresponds to the original TAC+ random Noise.

Resulting is the map(s) of the selected parameters (K1 in this example).

Next user is able to do some basic statistics on the specified parameter, K1 in this case.

Corrected and updated the "Open TAC as 4D volume" function.  This allows user to specify the *.TXT file containing the TAC.  User specifies dimensions of the resulting volume where which voxel is constructed given the specified TAC + random Noise (Noise level is specified by the User).

This functionality allows to perform Monte-Carlo modelling of the Dynamic Models.

Single Timepoint of the resulting volume where vox(x,y,z) = TAC[t]+RandomNoise(x,y,z)

Implemented User-level  Active volume "Mirror along axis" function. This is under "MainMenu>3D Projection>Mirror along axis".  Function is now working for all 3 axis {X,Y,Z}.

Implemented new User- Interface-level function that produces all 6 projections of the SulciPrint3D directly from the BrainMask.  There is no need to generate intermediate   SulciPrint3D structure. Function is under the MainMenu>Applications>BrainPrint>Generate SulciPrint2D from BrainMask (6 projections).

Initial tests of the "Snowball" methodology for automatic fluid registrations, segmentations, and organ localization.  In one scenario we would try to locate both kidneys on the volume, fully automatically, using only sparsely defined library of shapes.

Red is a template shape approximating a kidney.  Current positioning describes a step of iterations when template is moving across the volume with some substantial step (but smaller than the Snowball capture radius).

After just few iterations of a fully automatic procedure, we end up with this localization.  It has a certain match score.  Hypothetically, an automatic localization algorithm might work simply traversing all possible positions with step (SX,SY,SZ)<Snowball Capture radius.  Position with the highest score is chosen.

This is just for illustration purposes, how primitive features are constructed at each step of the iteration.

Loading ANALYZE file:  fixed defect of incorrect truncation of signed negative numbers to 0.

Implemented the "Blood Volume" User parameter for Sokoloff  Short\Long models.

Saving Active Dynamic model settings to FVX file:  corrected a design flaw.  Sometimes we change the number of Free and Output parameters in the models.  If this model was save previously to FVX file as an Active model the current version of FireVoxel often would not be able to load such FireVoxel file and it will be lost.  In the corrected version, only the warning that the Model design was changed would show but file would always be loaded.

Enabled loading of the GE-scanner diffusion dataset by providing a specialized procedure to load                 b-values from the private GE tags.

Sokoloff model (Long formula):  added additional user controls so the values of all parameters {K1,k2,k3} could be fixed during the optimization.  User simply set  k2_min = k2_max = Desired Value.

Sokoloff model (Short formula):  added additional user controls so the values of all parameters {K1,k2,k3} could be fixed during the optimization.  User simply set  k2_min = k2_max = Desired Value.

MainMenu>Volume>Smooth (and other smoothing operations):  restored correct operation on the ROI.

Implemented a new variant of smoothing of the Sparse Vector Field obtained as a result of the feature match. Jacobian of the smooth field is within the specified interval at all the voxels of the volume.

Implemented a function to measure a jacobian of the transformation corresponding to the Vector Field.
Implemented an iterative smoothing function of the Vector Field till the jacobian at every voxel falls within the specified interval of values.

Experimenting with the Nearest-neighbor based estimation of the sparse vector Field (this is instead of traditional gaussian smoothing step used in the literature:  Demons,ART, etc)

Deformable registration/segmentation:  implemented and tested local affine transform functions around the "Focus of maximum displacement of the vector field"

Deformable registration:  experimented with using the Polynomial transforms obtained by Amoeba optimization using the Jacobian constraints.

Volume reslicing using polynomial transforms:  corrected imprecision defect due to incorrect rounding.

3. AutoFocus3D\AutoFocus4D providded separate allowance intervals for each of the axis {x,y,z}.
4. PET-FDG Motion correction:  increase speed by x10+ times.  This is base on the observation that gross motion is usually due to the "Turning of the head" rather than "Tilting" during exam.
5. "Small" vs. "Large" motion correction options were eliminated and folded into one single Motion Correction
6. PET motion correction:  modified default parameters to increase the search range for better registration quality without any speed penalty (compensated by choosing smaller radius in the URAL feature detector).

PET motion correction:  modified default parameters to increase the search range for better registration quality without any speed penalty (compensated by choosing smaller radius in the URAL feature detector).

PET-FDG Motion correction:  increase speed by x10+ times.  This is base on the observation that gross motion is usually due to the "Turning of the head" rather than "Tilting" during exam.  New FireVoxel functionality was used that allowed to set separate Max Rotation angle intervals for each axis.

"Small" vs. "Large" motion correction options were eliminated and folded into one single Motion Correction.

4D Kidney registration, case nucs05.  This is a large rotation (12+ deg) case.  Default registration parameters (max rotation) were increased to capture large rotation.  New feature of separate Max Rotation angles for each axis has allowed not to increase processing time.

Registration on the timepoint of the extreme rotation.

Here is the processing result in (.FVX)
https://drive.google.com/file/d/0B2lI9iEKOqv6UVFGclppVUEzWEE/view?usp=sharing
