PET-FDG motion correction.  Most challenging case (MB-15) of the last batch.  Before and after motion correction, reference BrainMask from the last timepoint (#38) is overlaid on the maximum displacement timepoint (#27)

Before

After

MainMenu>ROI>Clip Volume by ROI:   completely parallelized the implementation with great performance gain (on long 4D sequences).

FireVoxel Build 165 is released.

1. FireVoxel file save - disabled the PHI warning,

2. Fixed crash defect:  4D volume overlaid by 3D-ROI as active layer.  Calling EdgeWave function was producing crash.

3. Defect fix: EdgeWave algorithm on real-valued volumes:  provided correct conversion of units from the dialog box to the actual procedure.

4. Affine transform reslicing: substantially increased the parallelization resulting in about x2 speed improvement on the developmental 6-core platform.

5. SIG_DIFF registration measure:  changed accumulation from L2 to L1 norm.

6. UI - VolumeSmooth function:  Removed erroneous  "ROI required function"

7. VolumeSmooth (Median):  corrected the fixed memory allocation for the sorting, so the smoothing of double-valued volumes does not crash anymore.

8. Fully parallelized the VolumeSmooth procedure so it runs with the 100% load on 12-thread system.

9. Implemented initial variant of the "DICOM File Extractor" dialog box.

Implemented initial variant of the "DICOM File Extractor" dialog box.

Next iteration of CT file extractor dialog:

Initial Prototype of CT DICOM file extractor for VA grant.

Fully parallelized the VolumeSmooth procedure so it runs with the 100% load on 12-thread system.

VolumeSmooth (Median):  corrected the fixed memory allocation for the sorting, so the smoothing of double-valued volumes does not crash anymore.

UI - VolumeSmooth function:  Removed erroneous  "ROI required function"

DICOM Tree functionality:  decoupling the DICOM volume objectification functionality from the DICOM-Folder-Tree dialog box.  This is so that functionality could be used by other DICOM-related dialogs.

Register 4D volume to 3D:  major code re-engineering.

Registration of 3D/4D volume to ROI.  This frequent and useful scenario is greatly sped up by adding the "Target ROI" identical to the binary Target and inflated by 1 voxels. This improvement is only effective for the URAL-measure scenarios.

SIG_DIFF registration measure:  changed accumulation from L2 to L1 norm.

Affine transform reslicing: substantially increased the parallelization resulting in about x2 speed improvement on the developmental 6-core platform.

Defect fix: EdgeWave algorithm on real-valued volumes:  provided correct conversion of units from the dialog box to the actual procedure.

Fixed crash defect:  4D volume overlaid by 3D-ROI as active layer.  Calling EdgeWave function was producing crash.

FireVoxel file save - disabled the PHI warning, so it is the full user responsibility now.

FireVoxel Build 164 is released.

1. SulciPrint2D:   Added basic skeletonize functionality to binary SulciPrint2D.

2. MainMenu>Volume>Pad:  added the function to pad\extend volume with "0" fringes of the specified size (in mm).

3. BiCal post ISMRM follow-up and corrections.  Introduction of the new BiCal version - Multipass. Original BiCal is rebranded "BiCal Basic" on the user interface.  BiCal Multipass becomes "BiCal" on the user interface.

4. Corrected the cleanup of the FireVoxel working directory upon start\close of the Application.

5.Completely new BiCal algorithm is introduced with greatly simplified interface.

5. Included additional heuristics into the loading logic of the MIDAS  *.time files to correct the reported loading defect.

6. FireVoxel ABT: for each of the time-based dynamic model added an option to run the test both for the FVX file format and MIDAS file format.  Three actual models are verified in this dual mode.

7. Corrected: when in a 3 or more layer volumetric entity, the ROI is selected and the other layers are SI-volumes, a crash occurs right after the "Ambiguous layer configuration" message.

8. All Dynamic parametric models:  non-functioning "Process All" option was restored.

9. F9 function key brings up the FVX "Save Document" dialog box.

F9 function key brings up the FVX "Save Document" dialog box.

All Dynamic parametric models:  non-functioning "Process All" option was restored.
