Registration by DICOM-tags only.  Corrected the defect so that the Window\Level settings after the operation are exactly those of the source volume.

Breast FGT project:  PRE- and POST- image registration in case of the different dimensions. Registration is done using DICOM tags only.  Processing time <5 sec.  Alignment seems to be good.
Alignment of PRE- and POST- images in FGT project after DICOM-tag registration.
DICOM loading of the files containing Rescale\Inrtercept information:  Improvement to user interface was done.  Even if the Rescale\Intercept are "trivial" (i.e.  1/0) we now ask the user if the volume has to be loaded as INTEGER or REAL.  In case of REAL user needs to specify additional offset\factor.
This fixes the practical problem with some of FGT breast exams.

Pressing SHIFT button is NOT required anymore during the "Select by rectangular Net" function when mouse is dragged and selects all the objects within the rectangular area.
Change of the workflow for using the Window Level\Width tool.  User now has to press the new  Window Level\Width button on the Toolbar.  This puts FireVoxel into the "Window Level\Width" mode with the appropriate Mouse Cursor change.  Then user can change the Window Level\Width several time.  On Pressing ESC  the cursor changes back to "SELECT" mode.

This design is now matching the one in Synedra Viewer.

!Important:  This also fixes error when then  View Filter  Window Level was randomly changed after loading the Vector ROI.  This was happening because the Mouse Move command is sent after the closing the Open VROI file dialog.  This Mouse Move was erroneously interpreted as the request to change the Window Level\Width.



RoiStats 3D could be applied to specified range of values in data.
Specify "Value Interval [Start,End]" parameters.

Implemented fully functional version of Breast FGT measuring workflow.
Updated the Batch parameters dialog to include N3 parameters.


Fixed the defects with the Status bar progress indicator in
VolChangeResolution and VolN3 functions.
Fixed defects with the progress status bar text messages while loading the FVX document.

MainMenu>Volume>Crop with 4D ROI- all layers.  "Enabled" flag is now copying correctly for all the layers in the entity.
Layer Control Dialog> Load DICOM :  now using current UserOptions.LoadDicomFolder settings.
MainMenu>ROI>List All VROIs function now displays the message  "No VROIs are present".
Provided an initial coding of the Breast FGT Batch processing dialog.

FGT Batch dialog, initial layout. It is similar to CT batch processing layout.





1.  Source folder specifies where the folder containing the FVX files is.  It might have  subfolders.
2. Output masks:
    2a) checkbox specifies if they have to be output
    2b) Location specifies where the masks go
3,  Output log specifies output text file.

FireVoxel Build 200

1. Fixed entropy calculation
2. Fixed crash defect: in Dialog Open DICOM:  when Browse functionality is used to change the DICOM folder, pressing the Info button causes the crash.
3. DICOM open dialog:   fixed the loading problem when very long path of the DICOM file is specified.
4. N3-nonuniformity correction tool - enabled to work with Real-valued volumes.
5. Enabled BiCal to work with the Real-value images. Processed sodium image with BiCal.
6. Fixed the "total non-function" defect in VA_VolMul (Volume Multiply) function. This was used in Sulci Depth detection and BiCal.
7.Implemented initial version of perivascular space segmentation under "MainMenu>Segment>Detect Bright Spots" with the Dialog.
