Investigating the reslicing problem after the registration.
Correcting the IDIF function,  for Axial-SingleSlice variant.  It should behave correctly in {NoSeed,SingleSeed,MultiSeed} modes.

FireVoxel 128D is released with the   4DPET-MRI scenario fixes.
4DPET-MRI registration:   Corrected the workflow so user could choose the "Best" or maximum resolution evaluated individually at each axis.  Registration result is good.  Importantly, notice a non-trivial rotation angle between MRI and PET.  On this screenshot they are registered, but observe the MRI slanted margins, indicating ~2 degrees relative rotation as determined by the registration.


Helping to process the MRI+PET case obtained from Dr. Wahle.   MRI is in Axial, which is different  from the documentation.
Updating the IDIF function for a case when no MACRO-seed is present at all and instead user chooses simply the slice on the Axial projection.
Play 4D function:

  • Rewind if we are on the last frame
  • Use the default the interval to the last one used
  • Indicate the use of real intervals

Investigating a substantial memory residual remaining after the PET-to-MRI registration  ABT subtest.
Updating the Automatic Build Test   for 4D-PET and MRI co-registration.
Dialogs   {AutoFocus3D,AutoFocus4D} :  removed "URAL Interpolation" parameter with the purpose of simplifying registration User Interface.   URAL Interpolation = true, in all registrations.
Documenting the changes in the PET workflow after the change to the Axial projection.  Updating the manual.
Found solution for the registration of the Femur\bone ROIs. This is for the same patient, longitudal study.

Updating and restructuring the registration workflow to principal Axial-projection and accommodate new requirement to either reconstruct to Anatomy or PET resolution.

FireVoxel Build 128B is released.
Made Parametric Calculation call smarter - in case there is a single 4D layer is present, it is selected automatically and User does not have to make it Active.
Major code refresh for:
Dynamic Processing dialog box
Dynamic parametric map calculation - UI Application level
All models in Dynamic Processing DLL are revisited for
parameter consistency.

Parametric modelling dialog layout is rearranged to accommodate longer labels automatically generated for Input Functions.


RoiStats4D dialog:  when TAC for the ROI is obtained, its label is automatically formed consisting of the Roi Name + ROI size in mm3.  This allows user to avoid manual typing in when importing the Input Function inside the Parametric Modelling dialog.


Dialog Roi Stats4D:  Added the "Show Median"  checkbox (as apposed to "Show Average") .  Roi TAC is shown either in Median or Average mode. Same choice for Saving and copying it to the Clipboard.
