Fully implemented  PET-CT-Atlas\Rodent workflow. Tested on the Rat dataset with 30-region Atlas.

New Layer Control dialog:  implemented
a) Enable All, Disable All buttons
b) ROI operations "Combine" button with a dialog option to remove the Source Operands layers.

Build 219 is released.

New Layer Control dialog:   Enabled "Open DICOM" and "Open RAW" items.

New Layer Control dialog:  enabled the "New ROI 3D" and "New ROI 4D" buttons.

New Layer Control dialog:  Enabled the ViewFilter button and functionality.

New Layer Control dialog:  added Left Doubleclick processing (name change edit\Ctrl ROI midslice jump)

New Layer control dialog: Added the "Info" button handler.

"Hover over ROI atlas" functionality was added. When there is an Atlas-like combination of ROIs is present, mouse cursor position is analyzed and the name of the single ROI layer is displayed that present at the mouse coordinate.

ROI compression\RAM allocation:  fixed major inefficiency defect, so that the RAM requirement for the 174 ROI atlas was reduced from 1GB down to 20 MB.

Old Layer Control dialog:  fixed the crash when  number of layers was exceeding the maximum (21).

Expanded the Atlas->ROI conversion function.  Tested on 174 ROI atlas.
Some performance issues have to be addressed with such high number of ROIs.

New Layer control dialog Added "Up\Down layer"

Enabled the Transparency-Slider functionality inside the new Layer Control Dialog box.

New Layer Control dialog box:

Added the "Active voxel layer" info dialog box and the GoTo (to Advance and Select Active layer) function.

Cursor hovering over the active layer with Real values now displays  "Real= ...value"

Implemented the ABT subtests for the DDC\Alpha model, new IVIM, IVIM-segmented models with the new parameters.

Implemented the ABT subtests for the DDC\Alpha model, new IVIM, IVIM-segmented models with the new parameters.

Added new Dynamic Model:  "DDC Stretched Exponential fit S = S0*(exp(-b*ADC)^alpha)"

Tested on the standard ABT dataset identical to ADC:

DDC fit:  DDC=0.0016, alpha=0.34, Residual=2.03

For comparison, we performed the ADC fit on the same data:

ADC fit:  ADC=0.001152, Residual=12

Corresponding Alpha-map processed over the ROI

IVIM (Basic and Segmented) models:  changed the output parameter  Dt ->  Dt*(1-f)
