Build 446 is released.

 1. Minimum Spanning Tree algorithm update with keypoint re-arrangement in the order of the Tree width-first traverse.

2. FLEXR: developed a multipass version of this algorithm running on 1/3 of RAM.  Multipass allows to start minimum spanning tree from several distant positions to compensate for tree approximation.

3. NW flow field generation:  provided an AVX256 implementation for x2 speedup.

4. NW flow Sparse-to-Dense:  implemented algorithm for filtering out remote keypoints for speedup. This was based on evaluating Y-Z exponents and introdducing some minor artefacts.

5. Volume-to-concentration conversion: fixed defect when VOID voxels were treated as regular ones calculating an infinite concentration as a result.

6. Completely re-engineered sparse-to-dense flow field generation for upto x20 speed up (on CT Lung 5 mm grid)

7. Workflow>Breaset MR BPE : implemented Whole Breast Segmentation function

8. File>DICOM>Dicom Tree to Folders   : fixed defect when composite SERIES were not able to convert to folder.

9. VA_VolSegHist:  fixed defect. This function was returning thresholds measured in Histogram bins. Corrected to signal.

10.  Workflow>BPE breast :  added a one-click function for FGT segmentation.

11.  Workflow>BPE breast: added function for 3D motion correction.

12, MainMenu>Dynamic Analysis:   enabled work without supplying the T1-map so only T1W conversion is enabled.

13. Simplified the FLEXR 3D/MC menues.

Build 445 is released.

1. VA_RAW_VolSaveFile function: optimized when CurrTinx!=1 only the required timepoint is decompressed.

2. New GUI function: Convert folder of FVX files into a target folder with separate subfolder for each FVX file. For each FVX subfolder save all layers to NII files.

3. Provided FLEXR RAM estimation function and comparison to the system resources.

4. Updated MR Lung segmentation algorithm

Build 444 is released.

 1. FLEXR fixed defect so the registered volumes have the same Image Position\Orientation as the Target volume.

2. Updated the Machine GUID scrambling algorithm.

3. Neck multimodality workflow:  added the DWI Body Segmentation and DWI->GRASP registration.

4. Improved the FLEXR masking algorithm, both Smask and Tmask.

5. FLEXR perform corrections is Target->Source output option.

6. Fixed defect in bool VA_VolOverRoi_AvgMinMax, that was affecting the Optimal Intensity Window.

7. FLEXR3D works now when the Source volume is 4D, so it would reslice all timepoints and produce a 4D layer.

8. Fixed defect in DisplayVoxelInfo (status line), so the VOID voxel location show the dynamic index too.

9. Provided a first version of Neck Multimodality 15 step workflow combining PET, CT, GRASp,DWI.

10. Compare documents\compare volumes : provided the comparison function which works on compressed image data, so there is no need to decompress for the comparison.

11. Huffman compression of DICOM headers: upgraded to 64-bit and corrected when the longest H-code exceeded 24-bit.

12. Updated the Machine GUID scrambling scheme.
