Build 315 is released




1. Implemented the initial variant of the FLEXR - Motion Correction dialog box.






































2. Implemented an initial variant of the FLEXR- Motion Correction wrapper code. Tested in on 10-timepoints Neck DCE-MRI.
3.  Fixed one of the memory leak defect in FLEXR-MC.
4. Parallelized the TPS parameter calculation in FLEXR-SYMM variant
5. Added a "Output : Real Voxels" option in the FLEXR-MC dialog.
6. Fixed the Dynamic Dimension defect when loading DWI images and selecting the "Selected and Checked" DICOM load.
7. Replaced DICOM load choice with "Selected only" and "Checked only".

Build 314 is released.

1. Implemented a module for synthetic testing off some Dynamic Models. Tested the M49 DCE Reference Region model and fixed the calculation defect.  Residual cut by half.

2. Enable the 3D Raster Paintbrush.  Added the correspoding option to Paintbrush Dialog.


3.  When the "Synchronized 3D Cursor" UI option is enabled, it now works when the Paintbrush is applied.








4. Implemented far more precise (when K->0) formula  Func[i] = Integ<G(u)*exp(-K(X[i]-u))du> 
This affects many models using this convolution, resulting in higher precision for cases when K->0

5.  Fixed 32-bit buffer size overflow in VA_VolGetAll() function.
6.  Added Progress bar to  Layer Arithmetic operations.

Build 313A is released.
1. Model 49 (DCE Reference Region): corrected crash in voxel-wise processing.
2. . Model 49 (DCE Reference Region): added ABT subtest

FireVoxel Build 313 is released.

1. Imlemented Model #49: MR 2 compartment Reference Region model (Yankeelov 2005)
2. RoiStats4D dialog: displaying the curve without offset now to avoid visual confusion.
3. UI:  Re-enabled BiCal option to output the Bias field
4.  Verified that Model #49 with the Identity test, i.e. running on Reference Region returns RR {Ktrans,Ve} with high precision.
5. Open DICOM dialog:  corrected the defect when Copy operation and there are several source files
in different source folders but with the same file title resulting in overwritten files.
6. Fixed a typo error in the determining DICOM frame exact acquisition time.
7. Implemented Volume>Voxel Value Conversion> Change Transparent Signal.
8. Model #31 (MRTM2) fixed defect when the output Parametric Map color scheme was not initialized.
9. Fixed defect in 2-Volume Max Difference function
10.  Removed redundant HCT correction from some models

11. Added ability to add\modify the DICOM tags  {TE,TR,FA}


12. Fixed the defect in Dynamic Experiment dialog: when the IF and Tissue Concentration dialogs appear then {TE,TR,FA} fields are filled properly from the Volume DICOM tags

13. Enabled the FWTE calculation of the Concentration->Signal so it can be used in Modelling.

14. Extended the "Edit DiCOM tags" functionality to optionally Edit all the timepoints at once.














15. Volume Value Conversion dialog (after DICOM load): change layout to make functionality more clear so Add\Mul are applied ONLY when loading as INTEGER.











16. Corrected the imperfect shape of the Raster Paintbrush at small radii.
