Build 458 is released.

 1. When parsing the DICOM tree: we determine if the files were deidentified and in that case we add the PatientID to distinguish between different patient's records.

2. Corrected defect:  New layer addition and paintbrush usage now set the DocumentModified flag. So there is a warning when the User tries to close the document.

3. FLEXR3D processing dialog: added an option to save FFF (flow field file).

4. MainMenu>Tranform:  added an option to transform using FFF file.

5.  FLEXR3D\FLEXRMC added warning when SSC measure is selected to ensure the feature keypoints are enabled.

6.  Added UI Function>Test :  Combine Probability Maps to Atlas.

7.   Added UI Function>Test :  Sharpen template using Atlas

8. FLEXR cross-correlation similarity measure:  on large appertures (~16vox) obtained a 20% speed up by re-arranging the memory access during parallel execution.

9.  FLEXR SSC measure calculation : removed a major memory leak.

10. Further optimization of Crosscorrelation measure (FLEXR):  using the x86 superscalar instructions and 32-bit floating precision, achieve 32 threads X 16 superscalar operations = x512  parallelization.

11. Removed NGF (Normalize Gradient Field) similarity measure from FLEXR3D\FLEXRMC dialog options.

12. Enable the SSC similarity measure in FLEXR-MC dialog box.

13. Model 17 (IVIM segmented fit):  substantial update with improved parameter ranges etc.

15. Parametric modelling dialog: when model changes - the Output parameters selection gets all unchecked to avoid confusion.

16. Corrected behavior when the new layer is added and it has diferent spatial attributes.  Now it ensures that everything matches to the base layer (resolution, slice position, orientation, etc).

17. Merged PWR.DLL and VolumeAnalyze.dll (VolumeAnalyze is removed from distribution now). This is done for linkage efficiency and removing redundancies.

Build 457 is released.

 1. Open DICOM folder:  fixed crash when the folder is empty. Provided diagnostic.

2. Fixed crash when multi-frame file is invalid. Provided diagnostic.

3. Corrected defect:  when the ROI or other layer with different resolution from base is added, now ALL spatial information is properly copied to the new layer.

4. Fixed hard to find defect:  when function FindLayerContainingName was called, the whole name of the layer including PATH was checked. Corrected: only the name title is checked, because the path contained the searched name (like Atlas)

5. Fixed defect when loading zip-compressed headers embedded in FVX files.

Build 456 is released.

0. DICOM load, STUDY construction was corrected.

 1. Defect fixed: Parametric map calculation is skipped for a voxel that has a VOIDVOX at some point.
