Build 271 is released.

1. Added the "3D Processing" option to the  Segment>Detect Bright ridges  dialog box.

2. Implemented "3D Processing" option in the Volume>Smooth  dialog box.

3. VolumeSmooth in 2D:  implemented a pure, fully parallel 2D function.  It is D-times faster,
where D is the diameter of the apperture than the previous version.  D can be quite large  20-50 in
some segmentation scenarios.

4.  Developed morphological segmentation "Unlump ROI" procedure.
Applied to Lungs ROI.  When lungs are segmented, usually both lungs ROI is lumped together and to other small objects.  Unlump procedure runs and then we take 2 largest connected components.

5. Implemented an initial prototype of fully automatic Lung segmentation from MRI
GRASP-4D exam.

6.  Implemented the Volumetric Time Profile dialog.

7.  Implemented the Lung Static split based on   ROI Union algorithm.  Applied the volumetric time profile dialog to it.

















8.  Optimized the VolumeSmooth function in 2D with  Appeture weights = constant.  Used 256-bit AVX2 instructions for array  Multiply\Add

9.  Introduce the Roi Compression switch ON\OFF which can be called withing heavy computation procedure to substantially speed up calculation, without involving Users input into  User Interface Options.

10.  In multiprojection view with the synchronized cursor:  allow now to scroll through time synchroniously.

11. VolumeSmooth function: added the processor test for AVX2 capabilities.

12.  Change to menu item Volume>Change Volume Type function.  Added ROI->to->Integer conversion UI item.

13.  Implemented first prototype of fully automatic trachea segmentation from 4D MRI GRASP.

14.  Added the spirometry measures {FEV1,FVC} to Volumetric profile curve dialog.

15.  Implemented a new scheme to reduce the DICOM header size stored with each slice.  Space reduction is x2.

16. Implemented a single dialog to specify 3 integer values. This serves as the dialog for Lung splitting at the moment.

Achieved new result in Chest Wall segmentation from GRASP data.

FireVoxel Build 269D is released.

1.  Texture  Analysis Batch:  fixed defect when disabled layers were processed too.
2. Texture  Analysis Batch:  fixed the text format defect in the results (.17g)
3. Texture  Analysis Batch: Implemented Use Full Range checkbox option


4.  Layer Control dialog:  when adding a new Layer with the resolution different from the base,
the resolutions are displayed and option is offered to proceed and change the new layer resolution
to the base.

FireVoxel 269C is released

1.  Fixed defect in RoiStats3D\Blob Statistic when blob can contain some void voxels.

2.  Rolled back to 269A and reimplemented changes of 269B.

1. ROI colume Save to DICOM:  removed the dialog specifying the change of encoded bits.


2. Fixed defect with constructing DICOM  TAG_STUDY_UID when volumes originated from data other than DICOM. This allows outside packages to load volume with all slices.




3. Removed the MainMenu>File>Save DICOM Extended option and merged the functionality with the >Save DICOM function.

4.  Dialog RoiStats3D:  Save Stats - increased the text output precision of real numbers to the full possible precision.

5.   Texture Analysis batch log file: increased the text output precision of real numbers to the full possible precision.

Build 269A

1. Fixed the defect when not able to save a ROI to DICOM

FireVoxel Build 269 is released.


1.  Fixed defect in RoiStats3D dialog: when mouse cursor sliding over bin was displaying the
info for a different adjacent bin.

2.  Layer control dialog defect fix:  When User was unchecking non-Active layer, that layer became Disabled but Active.

3.  Fixed defect when  Volume was not loading with "SVD error" message.

4.  Texture Analysis Batch:  corrected the defect so that only Enabled volumes are analyzed.

5.  Fixed defect in  Volume>Convert Integer to Real.  Incorrect volume type was previously produced.

6.  Fixed normalization of the result when computing  Texture Gradient\Texture Edge maps.

7.  Enabled texture analysis batch for Real type volumes.

8. Added the "EMD\SigDiff" checkbox option for using different metrics for the gradient.

9.  Rename the "Texture Analysis Batch" dialog and menu item into "Region Heterogeneity Analysis Batch".

10.  Changed the Histogram calculation logic, so that the Range specified by the User kept as the Histogram range.  This applies both to RoiStats3D and Batch Dialog.

11. Fixed crash defect with Nbins=0, for {RoiStats3D, Heterogeneity Analysis Batch }

12. RoiStats3D : Made Histogram parameters preserved between the sessions of dialog.
