Build 334 is released.

1. MagTrace defect fix:  when changing slice and restarting MagTrace the contour from the previous slice was restarted and invisbly modified.

2. MagTrace defect fix:  crash when the current spline is exited, deleted and the new spline is started.

Also, includes this fix: Open a document, draw a new spline, delete. Start MagTrace, crash.

3.  MagTrace defect fix:  crash when pressing Alt+1(add anchor) outside the existing selected spline.

4. MagTrace fix: Copy selected spline (Alt+5) or Copy from adjacent slice and snap - Crash. 

5. MagTrace Overlay Edges UI function: fixed the crash and moved this important function to under the Test Menu.  It is used to explain the results of Edge snapping during the regular MagTrace processing. The EdgeMap is upgraded to double Real values now.

6. VolSetBox\VolSetSlice functions: added support for 16->64 bit conversion. 

7. Fixed and extended the Rasterization issues:

Toolbar button : Rasterize selected vector entities

But also under MainMenu>Vector> there are

4 commands:

Rasterize selection

Rasterize All Splines

Rasterize All Polylines

Rasterize All VROIs

8. Added duplicate commands {Construct vector ROI,Construct vector Polygon} accessible through the MainMenu>Vector.

9. MagTrace dialog: updated the dialog title and the names of some parameters.

10. Updated the title of Polygon\Spline properties dialog.

11.  Polygon\Spline drawing : enabled alpha filling mode with variable opacity by switching to Gdiplus engine.  Fixed various issues related to "close contour" option and filling.

 

12. Code:  reduced and simplified m_position usage in entities.  

13. Polyline\Spline dialog:  when properties are changed the entity redraws immediately with the new settings without the need to close dialog box.

14. Improved Hermite spline construction when the contour is closed by correcting the Tangent calculation.

 

Build 333 is released.

1. Code simplification in PWR.H: replaced several function with CString& parameter by functions returning a CString.
2. DisplayVoxelInfo intermittent crash on some projections: fixed by ensuring a single voxel condition in VolGetBox.
3. Implemented  ABT subtest for Single Slice {SAT,VAT,IMAT,MUSCLE} segmentation.
4. Profiled the rounding function rint(x) vs.  floor(x+0.5). The latter is about 10 times faster so switched to the floor() implementation.

4. Streamline the MagTrace parameter dialog.

5. MagTrace node positioning is working correctly on all projections now.  On non-original projections it does not perform the image snapping and defaults to Ctrl mode (precise position).

6. Modified UserInterfaceOptions so that  {LeftSideOnRight,PosteriorSideOnTop} applies only to image loading.  Also options are now stored in the Firevoxel Config file.

7. Fixed defect that polylines and splines are only displayed in their respective projection\slices.  Also spline can only be restarted if it is Visible in the current view.

8. {Polylines,Splines} can only be rasterized if they reside in the original projection.

9. {Polylines,Splines} have a new attribute "Close Contour" available through the Polyline dialog box. This attribute works with the MagTrace::AutoClose parameter which is now operational.
Also, the Alpha attribute for {Polylines,Splines} was introduce which controls the transparency of the Fill.

10. FVX file format  v10 was introduced to accommodate new attributes in {Polylines,Splines}. Formats v2-v9 are supported for loading.

11. Optimization of all Affine reslice functions (Reslice.cpp)

12. SetView Projection (-/+) buttons for the angles to change projection in real time.
13. Volume>Smooth Across dynamic dimension:  works now in any image type including real (64-bit). 

14. Fixed defect: saving FVX file with PHI information present the verification dialog was popping up twice.

Build 332A is released.

1.  User Options {LeftOnRight, PosteriorOnTop} are activated upon the load even if the projection is specified in FVX document.
2.  User Options {LeftOnRight, PosteriorOnTop} changed in the UserOptions dialog change the relevant projections of all documents immediately.
3. Defect fixed:  when *.time file for  collection of 3D NIFTI images, the orientation of the 4D volume is corresponding to the orientation of the individual NIFTI files.
4. Initial View Layout now enabled for loading of FVX files.

Build 332 is released.

1. Code: Removed unused code from the Nifti Load\Save module.
2. Code optimization: replacing RECT wirh RECT2D, eliminating PR_RectWi etc.
3. VectDotProduct variants : use the fma( x,y,z ) function instead of (x*y)+z for better precision.
4. Replaced pf_sign function implementation with the shorter template  (T(0) < val) - (val < T(0))
5. PWR.H : Complete  efficiency code review.
6. Complete implementation of T1rho Biexponential model. This includes testing for Bi\Mono type and reverting to Mono when required.
7. TSL datasets after cropping preserve the dynamic coordinate properly now.
8. FLEXR registration preserves the TSL (and other possible non-DICOM dynamic) coordinates correctly.
9. Allow User-directed main toolbar alignment through User Options dialog box.
 10.  New Knee-T1rho workflow button with registration items {FLEXR,AutoFocus4D} which work both on the knee and fathom.

11.  AVX2 256-bit instruction using FMA (fused multiply add) to speed up and improve precision of many functions such as {VectDotProduct, SVD, Cross Correlation within FLEXR}



13. Single slice abdominal segmentation: results of the segmentation are automatically measured and displayed (default dialog option = true).

14. Parametric Processsing dialog: a notion of Previously used model (PUM) is introduced, so it comes up as a default for the next loaded volume (unless it has its own model saved). If PUM is not compatible  with the loaded volume, we reset to Model 0 which is compatible with all volumes.

15. When in Dynamic Processing dialog box and no ROI layer is present, the "Process ROI as a single curve" changes to the "Process whole volume as a single curve".

16. Dynamic Modelling dialog box:  Extrapolate button is enabled only when the appropriate models are selected.

17. MainMenu>View : added several functions to close selected Views, Documents, etc.

18. Volume::GetModality function now returns MCLASS_NONE if modality is not present.

19. When any 4D image-file volume (non-DICOM) is loaded and the modality is not present, the dialog box will pop-up prompting user to specify the modality.

20. Fixed the crashing defect and proper operation for Backspace button when operating on the Polylines and MagTrace splines.

21. {MagTrace,Poly} tools:  if the spline or polyline is selected respectively, then starting the tool continues to work with the selected object instead of starting a new one.

22. Moved m_selection construct from individual views to a document (so it is shared by all Views).

23. When non-FVX Image is loading User can customize the initial layout between {FilmView, SingleSlice, Three Projection}.

24. When resolution info in image file (f.e. MIDAS) is invalid  or missing the warning will show up and the file would not be loaded.

25. Replace iround(double v) function with int(rint(v)) construct.

26. If Landmark registration is called and no landmarks are present, display the warning and exit (previously it was crashing).

27. Updated dialog window title. ROI -> Morphology -> Peel / Grow -> (dialog window title) Deflate ROI or Inflate ROI. Update to Peel ROI / Grow ROI.

28. When attempting to save FVX document where the PHI information is present, offer dialog with 3 choices: {Deidentify&Save,Save,Cancel}.

29. FireVoxel can have any of the predefined UI color schemes from under UserOptions dialog box.
30. Document background color can be customized now from the UserOptions dialog.

31. Code: replaced Entity:FindProjection( View) by View::FindProjection()

32. Implemented the RRSE (Root Relatived Squared Error) calculation an enabled it in models {26,50} (T1rho).

33.  Implemented ABT subtests for Models {26,50} (T1rho}.

34. Layer Operations dialog:  fixed crash when attempting to remove ALL unchecked layers. Added a warning too.

35. Saving FVX, if PHI is found the deidentify dialog show the tag names of all PHI.

36. File>Deidentify Document menu : displays the tag names if PHI is present, or informs otherwise

 37.  LayerOperations dialog is now activated through LayerControl dialog and able to reuse its functionality.

5. Fixed the "smudge" defect when moving and/or resizing the views. Now full Client Rectangle is always redrawn.











6. IVIM model outputs the solution interval and error bound information now.



7. Base Entity selection tracker is never drawn now  as it does not relay any useful information.

8. MainMenu>View>DisplayGrid  : setting 0 (mm) now make exactly a 1-voxel-based grid.





9. VROI dialog box : Increased coordinate precision to 1e-4. When defining the VROI its thickness is 1 voxel instead of 0. This fixed another defect when F11 the view change missed the VROI by one slice.
