{ FVX,MIDAS,DICOM }.  Added a new subtest for Tofts (Model8) from DICOM.

2.  Continue work on the ParSVD (1-sided Jacobi SVD/parallel). Replace the NR-SVD in the VolumeTransform function, fixed uncovered defects in ParSVD.

3.  Added an ABT subtest for the Volume4D->PCA function.

4. Use ParSVD engine inside the Vol4D_PCA function.

5. Replace and Unified all the instances of the SVD usage to a  ParSVD (1SJA) function.
This excludes the underdetermined systems.

6. String consolidation to the module-specific string tables.

11. Corrected defect of CT_BASIC concentration conversion not working in Dynamic Modelling.
12. Introduced an ABT subtest for TOFTS (Model8) on CT.

Build 294B is released.

2. Added a separate attribute "VTF_Folder" to User Options structure.

3.  Raster Paintbrush dialog:  rename "Parametric Maps" field into "Real Volumes"

2. Updated workflow for registering the Primate Atlas to the selected Monkey reference brain. Changes included:
    a) Using 0-component of the PCA (principal component) conversion of 4D volume.
    b) Using T2-layer as Anatomy for the label map.

    d) Label map is clipped by the provided Atlas Brain Mask.

FireVoxel 294A is released.

1. Removed the Temporary Folder cleaning upon the FireVoxel exit.  Now User views the Temporary folder size in the User Options dialog box.  User has an option to clean Temporary folder with dedicated button.

FireVoxel 294 is released.

1.  Implemented loading of the superPK files (*.idwc) into the FireVoxel dynamic component module.
2. Implemented an initial version of the MRTM0 model (with the reference function supplied by the superPK).

Reference function loaded from superPK

MRTM0 model fitting starting from time t* (equilibration time).

3. Implemented the MRTM model (using the loaded superPK reference function)

4. "Extract Atlas ROIs":  corrected so that the original Atlas layer is not removed after the operation.

5. Defect correction: In many operations when the layer configuration is modified, so if the floating Layer Control dialog is opened it was not updated leading to the confusion.

6. Extended "Integer Range Parser" support function used in many UI scenarios (f.e. Extract Atlas Layers).

7. Implemented workflow for Affine registration of Primate Atlas to the selected Squirrel Monkey Reference image.

8. Layer control dialog : added information about the number of marked layers. This is helpful when a very large number of layers is present.

9.  When layers are removed and a single layer is left, we set its Alpha to 100%

10.  Added the "Discard Alignment" item to the Transform menu.

11. Added "Save Alignment" function to the Transform menu.

12. UserOptions dialog:  added a general option for all the operations\transform which so far had only the default Interpolation. Now user specifies such "Default Interpolation".  Works including the Transform>Alignment tools.

13. Implemented a general high performance function for converting 4D Volume into array of Principal Component using PCA (resulting in new 4D Volume of components).

FireVoxel Build 293 is released.

1. NIFTI-4D: Corrected the each frame timing calculation using nim->toffset\nim->dt information.

2. Implemented a custom processing option for DICOM Open Folder dialog box.  Rarely DICOM datasets have SeriesUID unique for each slice, so the option was introduced to parse them correctly.








3.  Defect fixed: In NIFTI file obtained from SPM (type FLOAT64) there were many entries with the value  NotANumber, so this was making Firevoxel crash.  Fixed by changing these values to 0, during the load.

FireVoxel Build 292 is released.

1.  Several correction and improvements in the Dialog "View TAC"
2.  Major (x10+) acceleration of the saving FVX files with many slices, by improving the saving embedded dicom header structure.  This is done by using new DCMTK functions DcmOutputBufferStream::.
3.  Provided more robust  IsMatchingVolume function (used mainly in ABT).  Problem was that for many 4D volumes, there are one or more dimensions (f.e. time and b-values) with repeating values in the dynamic coordinates.  This introduces randomness in the sorting order of different timepoints, so matching function was often failing without reason.  Addressed randomness by checking against all suitable dynamic coordinates.
4. Restored the ABT subtest and full functionality for the ChestWall\FullBreast segmentation. This was disabled during the upgrade of MagTrace contour tool while constructing the ground truth for the lung segmentation (ISMRM).
5. Implemented the "Display unmarked layers" checkbox inside Layer Control dialog, functionality to display the unmarked entries thus expanding possibilities of working with the Layers.
6. Modified Transform>Translate  and Transform>Rotate function to work on several Marked volumes, while unmarked volumes are stationary.
7. Layer Control dialog:  added  "Mark\Unmark All layer" button.

Build 291B is released.

1.  Corrected defects in X-correlation registration dialog
2. Provided individual menu item for the Mouse brain->Atlas registration
3. Provided new functionality to remove a range of dynamic points specified by the User.

1. AutoFocus 3D: implemented a variant with "af Uniform Scale" option.
2. Implemented 1st version of the Mouse brain (automatically extracted from Multiholder) registration to the standard Atlas.
3.  Corrected binning inside the AutoFocus\MutualInformation registration.
4. Corrected run-away defect with MI_NORM\Affine.

FireVoxel Build 290 is released.

1.  Fixed error when rasterizing Vector polylines and splines:  now the NULL pen is used so the rasterized boundary is much closer to the vector one.



2. Provided complete re-work of the MagTrace Toolkit:
Added several new image snapping modes, manual modes Alt1,Alt2,Alt3.  Rasterization tools.

3. Added DCMTK functions for loading DICOM headers directly from memory buffer (avoiding the intermediate file creation).  Resulted in x10 loading speedup.

4. Provided an initial version of VIBE4D + GRASP4D hybrid merge function.

2.  Completely parallelize multi-slice projections such as MIP.  Added a progress bar since
it takes longer time to display.

3.  Extended Kidney FAP segmentation to include the notion of Collecting System.

FireVoxel 288C is released.

1. Kidney segmentation: algorithm modification to remove 99%+ of medulla voxels which accidentally appear on the surface of the kidney.

2.  ROI>Morphology>Inflate\Deflate functionality:  made corrections so the Inflate-Deflate combinations are reversible with the same parameter.  Fixed side-effects in   BrainAtrophy and FLAIR Lesions functions.
