New version of the IDIF tracking function

 1. Implemented initial version of the Omni-directional IDIF.  

This is a Bi-directional tracking map. Max length in both directions is 70 mm. Color represents the "generation index".  VROI is macroseed in this picture.  Black color corresponds to Miniseed (generation=1).  

 

 

Corresponding IDIF function

 

 1. Fixed DICOM load problem.  DICOM file had  *.im extensions (identical to MIDAS). So expanded the list of possible DICOM extensions.

2. Disabled access to Test Menu items in Release builds. 

3. Implemented new Gamma-variate fir Dynamic Model and made it possible to be called directly from RoiStats4D dialog box.

4. Radiomics file output : Added Volume name to each line.

5. Radiomics dialog :  checkbox option to output Tab-delimited file.

6. Radiomic dialog: checkbox option to output Tab-delimited text to Clipboard to paste directly to Excel.

8. When parametric map is calculated, the new layer now inherits the orientation of the working volume.

9. Polyline properties dialog box : fixed defect Line width – Option does not work. 

10.  Alt+1  now works with polyline (in addition to spline) to click-insert a new point.

 

Build 338 is released

 1. Code: Replaced FireVoxel custom data types with new VC++ buil-in types {INT8,INT16,INT32,INT64}

2. RoiStats3D dialog - corrected a subtle defect when remembered previous Histogram settings result in "No Valid Voxels" situation with newly loaded image, so it is not possible to open the dialog.  In this situation "Exclude Outside Range" flag is reset to prevent this deadlock.

3. Code :  replaced class function CDrawSet::{CurrentTime,CurrentDynInx} with CDrawView.

4. Fixed defect: unable to construct VROI on some .im and old FVX files.

5. Fixed crash when calling RoiStats3D dialog after "Ambiguous layers present".

6. For RoiStats3D dialog and Radiomics execution: changed how the notepad.exe is called so the FireVoxel does not have to wait till user exits the notepad.

7. ViewTac dialog box: voxel radius is changed now by using standard spin control

to avoid keyboard entering.

8. Fixed crash in Dynamic Experiment : Extrapolate functionality.

9. Added checks for Extrapolated dynamic points to be different from original dynamic points. Exclude repeats from specified extrapolated points.

10. RoiStats4D dialog : fixed defect when it was not possible to change the Curve panel background color.

12. RoiStats4D dialog : removed redundant Info button.

13. Dynamic Framework:  changed output parameter units naming from mm2/s to mm2/sec

14. Removed redundant item MainMenu>4D Processing>Parametric modelling.

15. Output naming consistency in IVIM models #17 and #18.

16. Dialogs RoiStats3D\RoiStats4D, common behavior:  when VROI is present in addition to raster ROI program checks if a single VROI is selected.  If single selected, then a corresponding temporary raster ROI is formed, new ROI layer  is NOT added anymore. If more than one VROI layer is selected, the stop warning is displayed.

17. Fixed naming (ADC->DDC) in Model 21: DWI Stretched exponent.

18. Implemented proposed parameter name changes in models {17,18,19,21,28}

19. Temporarily disabled resizing of the Single Curve dialog box till fully implemented.

20. RoiStats4D dialog: made "Copy (clipboard)" and "Save" function to produce identical format.

Build 337C is released.

  1 Radiomics: implemented GLRLM feature class (16 features).

FireVoxel Build 337B is released.

 

 1. Radiomics : GLCM corrections:

    a) Pxplusy array calculation 

    b) HXY1,HXY2 calculation

2. Radiomics  GLCM: Checkerboard (64x64) AND (65X65) step (1) image:

   a)Verified distance=1, directions (0,2), directions(1,3).

   b) Verified identical features for directions 0-3,  1-3

3. Performed comparison to MAZDA radiomics GLCM on abdominal CT  tumor. Obtained a close match on all features except the 2 entropy features. Seems like Mazda is using log10() function in calculations (appears also in its documentation) instead of log2.  Mazda and FVX entropy measures differ by coefficient log2(10). Testing was performed on all angles separately and distances {1,2}

4. Performed correction in DICOM header cloning with different Source and Target geometry.

5. ABT subtest for registration of 3D volumes with different number of slices.

3. MagTrace is restricted to  the original projection (0,0,0) for now.

4. Moved Progress Message support functionality into FvxMem.DLL.

5. Restricted MagTrace tool to operate on the original projection only. Added a warning message.

6. SAT\VAT segmentation toll: restricted to Integer volume only. Added a warning message.

7.  UI function: Multiframe DICOM splitting into single slice DICOM files into specified folder.

8. UI function:  "folding" of the 4D multi-echo volume into the single echo TE=0 using T2star fitting.

9. When loading DICOM as a Real Volume (with Rescale\Intercept tags present), recover the RescaleType DICOM attribute if present and display voxel units accordingly.

10. After Loading dicom  Intercept\Slope tags are cleared, since the conversion of data is performed already and the original (before rescale) pixel data is discarded.

11. Added extra Fail diagnostics into FVX document save function.

12. SAT\VAT single slice segmentation:  added a check that a single Spline is required on the selected slice. If found only that spline is rasterized (as opposed to ALL in previous veriions).

13. Fixed positioning defect when moving vector entities incl. VROI as a whole (hold RMB).  Optimized the CDrawObj::MoveHandleTo function.

14. Optimization of { Volume,DICOM} deidentification functions.  If PHI tag is present but value is empty - it is considered absent.

15.Fixed defect :1. Start MagTrace and Esc (without drawing a line) – Crash.

16. Fixed defect:  Rasterize All Splines and Rasterize All Polylines – Both commands do the same.

17. DICOM load : made changes to extra Add\Mul logic with Rescale dialog box.   Changed the DICOMAUTOLOAD structure.

18. Implemented the Multi-Slice abdominal fat segmentation workflow from MagTrace contours on every Nth slice.

 

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.
