In perfusion image analysis, conversion from signal to concentration can be done using a native T1-map. Currently, this is only done in the DCE Perfusion Datafit View using the variable flip angle method, which is just one specific method to obtain T1-Maps. See also related task https://phabricator.mitk.org/T27047.
T1-Maps are generated as well in the CEST context, so this might be combined into one functionality.
In this task, a refactoring strategy is developed, which includes perfusion and CEST applications.
