FireVoxel Build 301 is released.


1. Fully parallelized the Foerstner Map calculation (for keypoints detection)
2. Corrected Jacobian map calculation for vector fields.
3. Corrected crash when calculating the EDT (Euclidian Distance Transform) in Parallel mode.
4. Corrected the MST optimization so the resulting displacement only resides in the areas
permitted by the Source ROI mask.
5. Processed a problematic case for Monkey->Reference registration.  Use Average (not PCA) to accumulate.  Use 3vox Rad in URAL gradients. Then following:





Pre-1

Post-1
6.  Expanded Tissue attribute structure to accommodate up 16 values.
7. Introduced FVX document v9.  Provided backward compatibility
for FVXv8.
8. Tissue Properties (such as T1 for ROI) are now save as part of the FVX file.
9. Eliminated legacy FDX_Text() dialog support,  Microsoft corrected the DDX_Text bug
for "double" fields.

FireVoxel Build 300 is released.

1. Implemented corrected Optimum Location calculation in the 3-D Euclidian Distance Transform.
2. Implemented capability for each Dynamic Model to restrict allowed Concentration Conversions to the specified subset.
3. Dialog Parametric Maps calculation:  presently selected Tissue and Input Function concentration conversions are displayed.

4. Dialog Layer Control: "Save ALL" functionality is implemented to Save ALL marked layers to the specified folder in specified RAW format.

FireVoxel Build 299 is released.

1.  Corrected FileExists function to work with files >2GB.
2. When loading the *.time file with TE info, the TE info should be in (sec) in *.time file.
At the same time the DICOM header stores that info in (ms), so the proper synchronization
was implemented.
3.  Implemented fully parallel algorithm for "Equlidian Distance Transform over Sampled Function" with the complexity O(n) where  n is the number of voxels. This is an important functional block inside larger Viterbi algorithm inside the Deformable Registration project.
4. Implemented new Model "3. Interleaved 2-state profile".

FireVoxel Build 298 is released.

1.  Fixed defect in MouseHolder segmentation: segmented subvolumes retain the 4D attributes of the original 4D Volume.
2. Fixed general defect:  when 4D volume with dynamic dimension other than time is transformed, the dynamic coordinates of the transformed volume are now correctly preserved.
