FireVoxel Build 176 is released.

PET4D<->MR4D registration:  implemented "ROI-crosscopy" feature that copies all the ROIs between Source and Target.

"Fill & Morph"   error explained:

Actually it does not seem to be an error.  Result is due to the few "unintended" ROI voxels in the intermediate slices.

Result is due to the few "unintended" ROI voxels in the intermediate slices (blue arrows)

With unintended voxels removed Morphing result appears to be correct.

Implemented the initial version of the synchronized multiprojection 3D cursor

T1-mapping (it-dynamic component):  fixed defect of incorrect scrolling in time.

Fixed processing of complex 4D Cine dataset where TAG_CONTENT_TIME was used to hold timing info.  Additionally  repeating times are now handled properly.

Cine images, timings are recovered - there are some repeats.

Corrected defect with  "Threshold to ROI" user-level function when the negative threshold is used.
Diagnostic message is added .

Implemented logic for loading MR images which after Rescale\Intercept contain negative values.

User is offered an offset so the minimal voxel value would map into 0.

Resulting loaded volume

Added ABT subtest for NIFTI 3D and 4D load.

"Save Active Layer to RAW": disabled the defect of not functioning for 3D volumes.

Dynamic segmentation Verification dialog:  added handling of the arrow keys so they are translated directly into Volume scrolling as usual handling of the volumetric document.

"4D  Segmentation by Patches" - fully parallelized with x5 speed improvement on reference machine.

Fully parallelized the ROI Tac calculation (F4) - great speed-up

Fixed a major "racing condition" during the parallel load of ".FVX" files.

Parametric model calculation for a Single ROI TAC:  expanded the progress message to include the name of currently processed model.

Parametric model calculation:  expanded the progress message to include the name of currently processed model.

Dynamic segmentation verification dialog (Segmentation by 4D-patches):  pre-calculate all the TACs for all ROIs during the dialog initialization so later on User has an instant access to all TACs.

Dynamic (4D) Segmentation  Verification dialog box:  added the Mouse Wheel response so user can scroll through slices without exiting the dialog box.

Renal GFR calculation (CERENE) - changed the default registration method to URAL (signal  gradient based).
