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).

Dynamic segmentation dialog: modified the dialog layout and added several addition options for the TAC normalization and comparison.

FireVoxel Build 175 is released.

NIFTI-1 support:  enable  FireVoxel load of images from the BPD dataset

Provided initial support for reading Nifti-1 format into FireVoxel.
Preliminary testing was done on sample files from NIFTI website
a)  3D   unsigned 8-bit
b)  4D  signed 16-bit

PET4D-MR4D registration:  added a content time difference check between MR-PET and an option to "not use the DICOM-tags initial alignment".  This is to fixed some studies where PET & MR were acquired not simultaneously.

Now correct result for RS registration:

When PET document is loaded, the times are now correctly recorded in absolute format (i.e. from 01/01/1900)

Case CV:
Quality of PET4D-MR4D registration (Binary mode).  PET and MR should be motion corrected prior to the registration.

Registration by DICOMTAGS: corrected defect when two  4D volumes are registred and placing as an additional layer produces a crash.

Fixed defect:  When multilayer document is cropped using Vector ROI, new document opens and ALL the layers are redrawn correctly now.

FireVoxel Build 174 is released.

FireVoxel 174 and higher was compiled with Visual Studio 2013.  It requires a one time installation of a new Visual Studio 2013 redistributable package.

It is available from Microsoft here:

Press Download button.

Then choose "vcredist_x86.exe"

Created a dedicated workflow submenu:  "MainMenu>Application>Renal workflow without AIF"

Kidney GFR Baumann-Rudin model:  fixed the calculation defect

Implemented Baumann-Rudin model for calculating the GFR

Get ROI Tac (RoiStats4D\F4) procedure: optimized performance so the speed is proportional to the size of the ROI.

Implemented UI-level function "Main Menu>ROI>Crop volume by ROI".  This takes {3D,4D} ROI, find maximum bounding box for all voxels and crops the current document by this box in 4D creating a new document.

Kidney Ctx+Mdl segmentation from GRASP-4D exam.  FVX registration is performed in this example.
