Support pre-clinical MR gel dosimetry workflow

[cpinter]

Mattea at UofT works on the pre-clinical MR variant of the gel dosimetry workflow. It seems very similar to the one we support now, except for some input types and nomenclature.

Meeting minutes from 2014.05.22.

• No VFF but DICOM
  ** We could move the VFF loading UI parts to step 1 (rename it to 'Load data'), and add role selectors for the two volumes. Thus the calibration and measured volumes could come from both DICOM and VFF
  ** The alternative is to have different "modes" for the slicelet, but that will get messy really soon (after having to add a third mode)
  *** Probably on the long run if we have more "modes", then we could have configuration files that the user loads up after startup, like a parameter set node that defines the inputs, axes names (see below), etc.
• Need to change the names on axes
  ** Optical density -> R1
• T1 map: signal intensity -> relaxation rate from multiple T2 time points
  ** Find out if t1 map computation is available in the 3rd party sw
• Send workflow chart to Mattea, she will mark the changes (for MR and general)

T1 mapping available in 3rd party software for pre-clinical workflow. T1 mapping algorithm would need to be implemented for clinical workflow (relaxation rate from variable TR imaging).

MRI compatible workflow attached (.png); Details outlined in "Workflow_changedetails.txt".

Set up meeting to discuss specific changes needed.

PLANCT is in .ini file format for pre-clinical workflow. Changes added to workflow .png file.
