FireVoxel Build 189 is released:

1. AutoFocus4D dialog box:  corrected a crash defect due to unsupported even handler after removing the SliceMode combo box.
2.Breast lesion registration:  updated default registration parameter to accomodate a requirement that a precise (not overinclusive) lesion ROIs would be provided.
3. AutoFocus3D\AutoFocus4D providded separate allowance intervals for each of the axis {x,y,z}.
4. PET-FDG Motion correction:  increase speed by x10+ times.  This is base on the observation that gross motion is usually due to the "Turning of the head" rather than "Tilting" during exam.
5. "Small" vs. "Large" motion correction options were eliminated and folded into one single Motion Correction
6. PET motion correction:  modified default parameters to increase the search range for better registration quality without any speed penalty (compensated by choosing smaller radius in the URAL feature detector).
7. 3D->3D,4D->3D} slice-by-slice registration:  implemented option for the current timepoint of source to be used to calculate a single transformation for all timepoints. Integrated this new functionality into the Breast lesion registration workflow.
8. "Layer Control Dialog> Load DICOM layer" :  fixed the defect  crash defect when "Load DICOM" button is pressed.
9. AutoBuild Test added subtests for:  DialogAutoFocus3D, DialogAutoFocus4D, EPI->T1 registration in Breast lesion workflow, for the automatic segmenation of Blood Vessel map, CERENE3D  kidney perfusion coregistration.
10. Breast lesion workflow:  added functionality and user interface to register PET-3D volumes to T1-3D volumes.
Auto Build Test:   added subtest for CERENE3D  kidney perfusion coregistration.
AutoBuild Test:  restored the subtest for the automatic segmenation of Blood Vessel map.

AutoBuild Test: added subtest for EPI->T1 registration in Breast lesion workflow.
AutoBuild Test:  added subtests for  DialogAutoFocus3D  and DialogAutoFocus4D.
"Layer Control Dialog> Load DICOM layer" :  fixed the defect  crash defect when "Load DICOM" button is pressed.

{3D->3D,4D->3D} slice-by-slice registration:  implemented option for the current timepoint of source to be used to calculate a single transformation for all timepoints.

Integrated this new functionality into the Breast lesion registration workflow.
PET motion correction:  modified default parameters to increase the search range for better registration quality without any speed penalty (compensated by choosing smaller radius in the URAL feature detector).

PET-FDG Motion correction:  increase speed by x10+ times.  This is base on the observation that gross motion is usually due to the "Turning of the head" rather than "Tilting" during exam.  New FireVoxel functionality was used that allowed to set separate Max Rotation angle intervals for each axis.

"Small" vs. "Large" motion correction options were eliminated and folded into one single Motion Correction.

4D Kidney registration, case nucs05.  This is a large rotation (12+ deg) case.  Default registration parameters (max rotation) were increased to capture large rotation.  New feature of separate Max Rotation angles for each axis has allowed not to increase processing time.


Registration on the timepoint of the extreme rotation.

Here is the processing result in (.FVX)

AutoFocus3D\AutoFocus4D providing separate allowance intervals for each of the axis {x,y,z}.  This would potentially allow to achieve  high speed gain in registration by selecting only some axis where the principal rotation occurs.

FireVoxel build 188 is released.

1. Developed command line interface and *.exe module to access all the functionality of the Dynamic Modelling module.
2. DicomOpen dialog box: corrected crash when STUDY item is selected and attempted to load.
3.DICOM Open dialog box:  combined 2 buttons for loading 4D volumes into a single  "Load 4D" button.  This replaces "Load Siblings" and "Load Range 4D" buttons.
4. 3D\4D registration and corresponding dialogs - allow individual axis of Autofocus to have separate MaxScale values.  This would allow to address registratios with the individual axis distortion (f.e. dr. Sigmund`s  PET-MR registration problem)
5. AutoFocus4D registration:  Reduced SliceMode option to  checkbox Mode2D. Moved this option to the MEASURE panel.
6.AutoFocus4D dialog box:  encapsulated the dialog header into the code file and exposed the global function for calling the dialog.
7.Implemented standalone User-level function "Register AutoFocus3D slice-by-slice"
8. Register by DICOM tags only:  implemented an option when user is asked to present result as the new layer or create an entirely new document.
9. Completely removed the 2D mode option from the Register 3D autofocus dialog box, since this function is a standalone at User-level.
10. Register 4D Autofocus,  "2D Mode" option is now an attribute of the VA_AF4D structure.
11. Removed the redundant "Correct orientation" checkbox from the Register Autofocus 3D dialog box.

12. Workflow breast lesion registration:  implemented a 1-click function to register EPI-4D volume to the T1-3D  volume.  Provided both {with ROI clip,no Roi clip} variants.
