Had a morning meeting with Yu-Shin. Demoed new functionality for PET load, TAC analysis.  Discussed priorities for the next week and corresponding functionalities to be developed.  Some glitches showed up during the demo and will be fixed in Build 125.

Investigating  T2/T2* mapping defect

K-trans dynamic modelling:  fixing a defect, model calculation is not performing as expected.
Testing on a sample prostate DCE volume.

Defect was due to the change of time convention in FireVoxel. From a certain Build, the Volumetric entity contains the absolute time in seconds, however some models require the starting time be "0".

This seems to resolve the issue.  Also added a new feature for this model - comparing the data curve to modelling curve. 

 We also are able to generate voxel-wise maps properly. See a screenshot below. This is the K-trans map

PET project:   Was able to incorporate timing information for all frames. For this non-gated acquisition the following logic was used:
(Frame Reference Time (0x00541300)+Actual Frame Duration (0x00181242))/2


Now Dynamic PET datasets can be loaded, ROIs can be constructed and corresponding TACs (time activity curves) can be obtained.

3 ROIs and corresponding TACs

For this sample dataset:
