Developed command line interface and *.exe module to access all the functionality of the Dynamic Modelling module.

Monday, June 15, 2015

Provided additional options for deleting Vector ROIs (landmarks).


Added a small "Landmark\Vroi debugging tool".  Under MainMenu>ROI>List All Vector ROIs command.  Would show the list of all landmarks, with their corresponding time intervals and whether they are visible or invisible.

Restored the Automatic Build Test for the Model (34) "Sokoloff  using long formula"

Friday, June 12, 2015

Update the ABT test for "Sokoloff - short formula model".
For PET processing, added new logic - if user specifies the concentration conversion other than "Signal Values" - information dialog box pops up informing the user.  Then Signal is used for Concentration of Input function
Verified basic operation of the "T1-mapping using inversion recovery" model on the small phantom data.  "Modulus (1)" sub-method was used.
Upgraded the "AATH" to the new optimization approach:  Model calculation are performed by User-specified method.  Residual function estimates in terms of the original signal.


Restored the ABT subtest for this model.


Upgraded the "Modified Tofts model" {Ktrans,Ve,Va} to the new optimization approach:  Model calculation are performed by User-specified method.  Residual function estimates in terms of the original signal.
Restored the ABT subtest for this model.

Upgraded Tofts model {Ktrans,Ve} to the new optimization approach:  Model calculation are performed by User-specified method.  Residual function estimates in terms of the original signal.
Restored the ABT subtest for this model.

Restored the Automatic Build Test for models  {0,1,3}
Dynamic Modelling module "Process ROI as a single TAC" mode:  fixed interesting defect for all the models.  There was some undesirable "double->integer" conversion performed on the averaged ROI TAC.  So there was precision lost 0.5 units of signal on average.  Now fixed and is precise.
IN PROGRESS:   Verifying each individual Dynamic Model to work properly with the new Concentration Conversion mechanism.  Regenerating the ABT dataset
Upgraded APIs (application programming interface) to the Dynamic Experiment library so that  Callback functions for Signal->Concentration and Concentration->Signal are supplied for each model calculation.  This would allow each individual model perform fitting of the data in signal units instead of the concentration units.

Updated the design and layout of Dynamic Modelling dialog box
The Input Function view panel is removed.  Instead user can see the Input functions by
pressing the View button.  Then panel displaying all the concentration curves will appear.

Modified and enabled the ViewTac dialog to use the new mechanism of ConcentrationConversion.
Re-engineered the RoiStats4D dialog box. Ensured correct operation with the new Concentration Conversion design.

Wednesday, June 3, 2015

Finished initial implementation of consistent Concentration Conversion models through the entire FireVoxel.  Concentration conversion is now controlled by 2 dialogs:  "Concentration Method" dialog and the "ROI attributes" dialog.

The following dialogs had their User Interface updated:

1) ViewTac dialog
2) RoiStats4D dialog
3) Dynamic Modelling dialog box
4) Layer Control dialog box
